What made me most excited was to be able to help my family, being able to pull the burden out of them that theyve been struggling with. Thats what made me feel the best. Everything else to come, is to come. And were going to live life how we have been, just not going to have to worry about buying the supplies that I need.

  • Brain Lobes Overview

Our brains may be what make us who we are. As the seat of consciousness, the home to our memories, and the processing center for all of our experiences, the brain affects every second of our lives. Over time, experiences shape the structure and function of the brain, but one thing remains constant: all vertebrates have a cerebrum. This new part of the brain is a recent evolutionary development, with older structures such as the cerebellum and brain stem predating this complex organ.

Most scientists believe that conscious experience, including a sense of self, occurs in the cerebrum, which means that all animals with a cerebrum have the capacity for consciousness. The size of the brains lobes, the extent of their development, and numerous other factors–including social relationships–all affect the extent to which an animal is consciously aware.

Characterizing The Reasoning Process

Robust characterizations of reasoning should incorporate properties consistently appearing across different subjects and in different periods of time, and select analytical tools accordingly. For instance, perceptual response sensitivity to incoming signals, stability against noise, and minimal dependence on initial conditions favor tools capturing transient dynamics, which naturally reproduce these properties under appropriate conditions, over tools handling asymptotic activity, which fail to do so .

Reasoning’s relative instability and inefficiency suggest that optimal circuitry may need constant reconstruction and protection from interference, summoning protracted support of energetically costly long-range communications. Reasoning may be a sort of resonant regime, where functional efficiency would be achieved with specific, though unstable, spatio-temporal patterns. This suggests that reasoning should be studied with tools which can describe spatially-extended dynamic transients and can quantify information transfer and the corresponding energetic cost.

What Other Factors Does The Brain Take To Make A Decision

With each decision we create our life, since we are the sum of what we have decided. Developing the ability to make resolutions is crucial to shape the life we want since decisions are the engine that move our actions and influence the present and help create the future.

However, it is not always easy to decide. Sometimes we do it automatically and almost without realizing it, but there are other situations that paralyze us and we get stuck without knowing what to do. And it is precisely this disability that conditions conflicts in social, personal and work life.

Making a decision is taking a loss and nobody likes to lose. Deciding is ruling out, and in choosing one way to proceed we are omitting all the others. For this reason, action is often postponed.

Lobes Of The Brain And What They Control

The

Each brain hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions.

  • Frontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of smell usually involves parts of the frontal lobe. The frontal lobe contains Brocas area, which is associated with speech ability.
  • Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships . The parietal lobe is also involved in interpreting pain and touch in the body. The parietal lobe houses Wernickes area, which helps the brain understand spoken language.
  • Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision.
  • Temporal lobe. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.

Some Key Neurotransmitters At Work

Neurotransmitters are chemicals that brain cells use to talk to each other. Some neurotransmitters make cells more active while others block or dampen a cell’s activity .

Acetylcholine is an excitatory neurotransmitter because it generally makes cells more excitable. It governs muscle contractions and causes glands to secrete hormones. Alzheimers disease, which initially affects memory formation, is associated with a shortage of acetylcholine.

Glutamate is a major excitatory neurotransmitter. Too much glutamate can kill or damage neurons and has been linked to disorders including Parkinson’s disease, stroke, seizures, and increased sensitivity to pain.

GABA is an inhibitory neurotransmitter that helps control muscle activity and is an important part of the visual system. Drugs that increase GABA levels in the brain are used to treat epileptic seizures and tremors in patients with Huntingtons disease.

Serotonin is a neurotransmitter that constricts blood vessels and brings on sleep. It is also involved in temperature regulation. Low levels of serotonin may cause sleep problems and depression, while too much serotonin can lead to seizures.

Dopamine is an inhibitory neurotransmitter involved in mood and the control of complex movements. The loss of dopamine activity in some portions of the brain leads to the muscular rigidity of Parkinsons disease. Many medications used to treat behavioral disorders work by modifying the action of dopamine in the brain.

Brain Anatomy And Functions

In this area, we will look closer at the brain’s anatomy and the functions of each structure

THE BASAL GANGLIA: A group of subcortical neuronal structures that work to start and integrate movement. They receive information from the cerebral cortex and the base of the encephalon, process it, and project it to the cortex, the medulla, and the base to allow for a coordinated movement. This group of neuronal structures works with the cerebellum to coordinate fine motor skills. It is made up of a few structures:

  • Caudate nucleus, which is a “C” shaped nucleus that is implied in voluntary movement control, although it is also implied in learning and memory processes.
  • Putamen
  • Globus pallidus
  • Amygdala, which plays an important key role in emotions, especially in fear. The amygdala helps to store and classify memories and emotions.

THE HIPPOCAMPUS: A small subcortical seahorse shaped structure that plays a very important role in the formation of memory, both in classification and long-term memory.

The Brain Is Flexible: Neuroplasticity

The control of some specific bodily functions, such as movement, vision, and hearing, is performed in specified areas of the cortex, and if these areas are damaged, the individual will likely lose the ability to perform the corresponding function. For instance, if an infant suffers damage to facial recognition areas in the temporal lobe, it is likely that he or she will never be able to recognize faces . On the other hand, the brain is not divided up in an entirely rigid way. The brains neurons have a remarkable capacity to reorganize and extend themselves to carry out particular functions in response to the needs of the organism and to repair damage. As a result, the brain constantly creates new neural communication routes and rewires existing ones. Neuroplasticity refers to the brains ability to change its structure and function in response to experience or damage. Neuroplasticity enables us to learn and remember new things and adjust to new experiences.

Although neurons cannot repair or regenerate themselves as skin or blood vessels can, new evidence suggests that the brain can engage in neurogenesis, the forming of new neurons . These new neurons originate deep in the brain and may then migrate to other brain areas, where they form new connections with other neurons . This leaves open the possibility that someday scientists might be able to rebuild damaged brains by creating drugs that help grow neurons.

General Inability To Speak And Understand Language

How to ACCESS ALL PARTS OF THE BRAIN, for real creative thinking

Widespread damage to the brains language centers can result in global aphasia. People with global aphasia will have an extremely hard time expressing and understanding language.

People with neurodegenerative diseases, such as Alzheimers disease, often experience loss of speech slowly over time. This is called primary progressive aphasia .

PPA is not Alzheimers disease but can be a symptom of Alzheimers disease. PPA can also be an isolated disorder without the other symptoms of Alzheimers disease. Some people with PPA have normal memories and can continue leisure activities and sometimes even work.

Unlike aphasia that results from stroke or brain trauma, PPA results from slow deterioration of one or more areas of the brain used in speech and language.

The Cerebellum’s Balancing Act

Next up is the cerebellum. The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination .

Because of your cerebellum, you can stand upright, keep your balance, and move around. Think about a surfer riding the waves on his board. What does he need most to stay balanced? The best surfboard? The coolest wetsuit? Nope he needs his cerebellum!

Be Good To Your Brain

So what can you do for your brain? Plenty.

  • Eat healthy foods. They contain vitamins and minerals that are important for the nervous system.
  • Get a lot of playtime .
  • Wear a helmet when you ride your bike or play other sports that require head protection.
  • Don’t drink alcohol, take drugs, or use tobacco.
  • Use your brain by doing challenging activities, such as puzzles, reading, playing music, making art, or anything else that gives your brain a workout!

What Part Of The Brain Controls Anger

Much like fear, anger is a response to threats or stressors in your environment. When youre in a situation that seems dangerous and you cant escape, youll likely respond with anger or aggression. You can think of the anger response and the fight as part of the fight-or-flight response.

Frustration, such as facing roadblocks while trying to achieve a goal, can also trigger the anger response.

Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression.

Parts of the prefrontal cortex of the brain may also contribute to the regulation of an anger response. People with damage to this area of the brain sometimes

Where Do Emotions Come From

Sides of the Brain

The limbic system is a group of interconnected structures located deep within the brain. Its the part of the brain thats responsible for behavioral and emotional responses.

Scientists havent reached an agreement about the full list of structures that make up the limbic system, but the following structures are generally accepted as part of the group:

  • Hypothalamus. In addition to controlling emotional responses, the hypothalamus is also involved in sexual responses, hormone release, and regulating body temperature.
  • Hippocampus. The hippocampus helps preserve and retrieve memories. It also plays a role in how you understand the spatial dimensions of your environment.
  • Amygdala. The amygdala helps coordinate responses to things in your environment, especially those that trigger an emotional response. This structure plays an important role in fear and anger.
  • Limbic cortex. This part contains two structures, the cingulate gyrus and the parahippocampal gyrus. Together, they impact mood, motivation, and judgement.

Do Different Brain Regions Control Different Functions

Doctors originally divided the brain into four separate regions for the sake of conveniently labeling anatomical functions. We now know that the lobes of the brain roughly correlate with a variety of functions. The temporal lobe, for instance, plays a key role in auditory processing, while the frontal lobe helps regulate attention and memory.

This doesn’t mean that brain regions control these functions. Many functions overlap across brain regions, and the functioning of one region often depends on another. Moreover, some research suggests that when there is damage to one region of the brain, other regions may compensate, suggesting that the brain is highly malleable.

This all means that the brain is an unpredictable organ. Much remains to be understood, and our understanding of which brain regions do what changes with each new brain study.

What Part Of The Brain Controls Analytical Thinking

The left hemisphere controls analytical thinking, in addition, it works together with other regions of the brain such as the cerebellum for this process.

It is well known that the brain consists of two halves or hemispheres connected to each other by an extensive bundle of nerve fibers called the corpus callosum. The left hemisphere manages analytical thinking while the right side is more inclined to intuition. The predominance of one over the other influences our personality and our way of acting.

Cerebral laterality refers to the different functioning of each of the hemispheres of the human brain. But this laterality is not total and both parties share many functions and collaborate and communicate with each other to perform each specific task well.

Analytical thinking is a type of thinking that involves reasoning and reflection on a certain situation or problem. We use it to decide what to do with a specific task or simply to reflect on something general.

It operates through the division of the object of study or problem into smaller parts that can be identified, categorized and analyzed, in order to obtain an answer or an adequate solution to what we want to solve.

When can we use analytical thinking? Practically always not only when it comes to solving mathematical or scientific problems, but also in everyday life or even in other areas of knowledge. We can use it to make decisions, resolve conflicts, reflect on an issue, understand the nature of a problem, etc.

What Do The Parts Of The Brain Control

The brain is the most complex part of the body. It controls our movements, communication, decisions and emotions, as well as our organs. Neuroscientists from Duke University write that the human brain is composed of six basic parts: the medulla oblongata, the pons, the midbrain, the cerebellum, the diencephalon and the cerebrum.

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Different brain parts often work together to control the body’s actions. Large areas are devoted to complex functions, such as the ability to have thoughts and feelings, to express them using language and to store them in memory. Neuroscientists are still working on deciphering which parts of the brain work together to accomplish such functions.

Does The Cerebellum Control Emotions

Brain

The cerebellum is particularly well-suited to regulate emotion, as connections with limbic regions, including the amygdala, the hippocampus, and the septal nuclei have been posited (Anand, Malhotra, Singh, & Dua, 1959 Annoni, Ptak, Caldara-Schnetzer, Khateb, & Pollermann, 2003 Harper & Heath, 1973 Schmahmann, 2004

Which Part Of The Brain Deals With Emotions

Now, you know what parts of the brain deal with thinking and memory. Lets have a quick look at the part that is responsible for emotions.

All positive and negative emotions, and spontaneous feelings think excitement and sadness, are being processed in the limbic system.

The limbic system control your emotions and interacts with other parts of the brain.

In the same time, another part of the brain called amygdala handles emotional reactions such as love, hate, and sexual desire.

With centuries of research, the human brain remains the biggest mystery in the world. It is the most complex part of the body that controls movement, sight, and thinking.

What Part Of Your Brain Controls Movement

Also, how does the brain control movement?

The primary motor cortex, or M1, is one of the principal brain areas involved in motor function. M1 is located in the frontal lobe of the brain, along a bump called the precentral gyrus . The role of the primary motor cortex is to generate neural impulses that control the execution of movement.

Beside above, which functions in the control of movement? The cerebellum is located in the back of the brain, just above the brainstem. Its important function is to regulate neural signals in other parts of the brain. Most is known about its regulatory actions on neurons that control movement and posture.

Hereof, how the brain tells the body to move?

Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When the impulse travels down the axon to the muscle, a chemical is released at its ending.

What part of the brain is responsible for thinking reasoning and memory?

The frontal lobe is primarily responsible for thinking, planning, memory, and judgment. The parietal lobe is primarily responsible for bodily sensations and touch. The temporal lobe is primarily responsible for hearing and language. The occipital lobe is primarily responsible for vision.

The Geography Of Thought

Each cerebral hemisphere can be divided into sections, or lobes, each of which specializes in different functions. To understand each lobe and its specialty we will take a tour of the cerebral hemispheres, starting with the two frontal lobes , which lie directly behind the forehead. When you plan a schedule, imagine the future, or use reasoned arguments, these two lobes do much of the work. One of the ways the frontal lobes seem to do these things is by acting as short-term storage sites, allowing one idea to be kept in mind while other ideas are considered. In the rearmost portion of each frontal lobe is a motor area , which helps control voluntary movement. A nearby place on the left frontal lobe called Brocas area allows thoughts to be transformed into words.

When you enjoy a good mealthe taste, aroma, and texture of the foodtwo sections behind the frontal lobes called the parietal lobes are at work. The forward parts of these lobes, just behind the motor areas, are the primary sensory areas . These areas receive information about temperature, taste, touch, and movement from the rest of the body. Reading and arithmetic are also functions in the repertoire of each parietal lobe.

As you look at the words and pictures on this page, two areas at the back of the brain are at work. These lobes, called the occipital lobes , process images from the eyes and link that information with images stored in memory. Damage to the occipital lobes can cause blindness.
