What Part Of The Brain Controls Fear

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

From a biological standpoint, fear is a very important emotion. It helps you respond appropriately to threatening situations that could harm you.

This response is generated by stimulation of the amygdala, followed by the hypothalamus. This is why some people with brain damage affecting their amygdala dont always respond appropriately to dangerous scenarios.

When the amygdala stimulates the hypothalamus, it initiates the fight-or-flight response. The hypothalamus sends signals to the adrenal glands to produce hormones, such as adrenaline and cortisol.

As these hormones enter the bloodstream, you might notice some physical changes, such as an increase in:

  • heart rate
  • blood sugar
  • perspiration

In addition to initiating the fight-or-flight response, the amygdala also plays a role in fear learning. This refers to the process by which you develop an association between certain situations and feelings of fear.

Which Part Of The Brain Is Responsible For Thinking And Memory

The majority of thinking-related processes happen in the frontal lobe. These include decision-making, problem-solving, and planning.

The frontal lobe also helps the development of cognition, language processing, and intelligence.

The temporal lobe controls other processes related to language understanding, perception, and recognition. It is also in charge of learning and memory.

Each Part Of The Brain Controls What

The brain is a remarkable organ and incredibly complex. The three main regions of the brain are the midbrain, hindbrain and forebrain, which is broken up into additional sections including the frontal lobe, occipital lobe and temporal lobe that control different parts of the body. All of these work together like a well-oiled machine to allow humans to function properly.

The cerebellum is located at the lower back part of the brain. This part of the brain controls equilibrium and balance and allows humans to move correctly. It coordinates the muscles and joins so they can work together.

The occipital lobe controls vision. It is located at the very back part of the brain and affects how humans judge everything visual, from how something moves to how colors register. Two signs that something is wrong in this area of the brain are if the person experiences hallucinations or perceives colors differently.

A part of the brain called the temporal lobe controls a very important part of a person: memories. In addition, this specific part of the brain controls language functions, sexual functions and personality. It also has an effect on how the person perceives verbal and non-verbal input.

What Is The Motor Cortex

The motor cortex of the is a region in the posterior part of the frontal lobe that controls voluntary movement. Neurons in this region of the brain send signals down the to the muscles to coordinate movements. The motor cortex is divided into regions that represent the regions of the body, and neurons in each region correspond with the movements in the related part of the body. This area is also involved with learning movements and coordination.

The motor cortex works in harmony with the premotor areas in the frontal cortex to plan out and execute voluntary movement. It is made up of Betz cells, special neurons that send axons down into the spinal cord. These axons communicate with spinal neurons by synaptic transmission. Betz cells are the largest neurons in the central nervous system and project into all the layers of the cortex.

Damage or to the motor cortex can lead to paralysis or difficulty with voluntary motor control. The paralysis will be on the contralateral part of the body, so if the right side of the cortex is damaged, the left side of the body will be affected. Damage to this area can also interfere with the learning of motor skills.

Which Part Of The Brian Is Affected During Memory Loss

Parts of the Brain and What They Do

We already mentioned that there is not one single part of the brain that is responsible for learning or memory, so there is not a single region responsible for memory loss either.

The frontal and temporal lobes, the limbic system, and parts of the brain stem that control alertness are all involved in memory and learning. So, if any of these parts get damaged, a person can suffer memory loss or amnesia.

The Parts Of The Brain That Effect Our Psychology Emotions And Behaviors

The brain is the most important and complex organ in our bodies. You dont have to be a brain specialist though to appreciate some of the basics about the brains role in emotions and behaviors in both ourselves and our children.

The brain is compartmentalised for our understanding but in reality all the parts work in complex, intertwined ways. The largest section of the brain and closest to the surface is the Cerebrum or Cortex. This is often broken down into lobes or sections of the brain: the frontal lobe, parietal lobe, temporal lobes, and occipital lobe. The frontal lobe is at the front of the head and is responsible for planning, organisation, logical thinking, reasoning, and managing emotions. This is the part you will hear about most regarding the expression and regulation of emotions and behaviors. It is also known as the higher brain, rational brain, or the upstairs brain.

Ok, now we are familiar with some of the major parts of the brain involved in behaviours and emotions we can look at how they interact with each other and influence behaviors through development, how we can help our kids understand what is happening, and what we can do to help our kids to better manage behaviors and emotions.

Tips For Boosting Creativity

If youre trying to nourish your creative side, here are a few ways to get started:

Read about and listen to the creative ideas of others. You might discover the seed of an idea you can grow, or set your own imagination free.

Try something new. Take up a creative hobby, such as playing an instrument, drawing, or storytelling. A relaxing hobby can help your mind wander to new places.

Look within. This can help you gain a deeper understanding of yourself and what makes you tick. Why do you gravitate toward certain activities and not others?

Keep it fresh. Break your set patterns and go outside your comfort zone. Take a trip to a place youve never been. Immerse yourself in another culture. Take a course in a subject you havent studied before.

Even something as creative as music takes time, patience, and practice. The more you practice any new activity, the more your brain adapts to the new information.

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.

The Role Of The Neomammalian Brain

Brain

The neomammalian brain is thought to be the last major development in the evolution of the human brain, due to its being the outermost structure and imaging studies which have shown this region is implicated in higher-order thinking. Functions of the neomammalian brain include analysis, sensory processing, learning, and memory, motor control, decision-making, reasoning, and problem-solving. The primary and overarching responsibility of the neocortex is to determine what is going on in the outside world. This function has a number of components, such as moving our sensory organs so they are in the best possible position for the receipt of perceptual information, processing the stimulus, storing an accurate representation, and mentally manipulating this representation so as to determine the best possible response.

The Cerebral Cortex Creates Consciousness And Thinking

All animals have adapted to their environments by developing abilities that help them survive. Some animals have hard shells, others run extremely fast, and some have acute hearing. Human beings do not have any of these particular characteristics, but we do have one big advantage over other animals we are very, very smart.

You might think that we should be able to determine the intelligence of an animal by looking at the ratio of the animals brain weight to the weight of its entire body. But this does not really work. The elephants brain is one-thousandth of its weight, but the whales brain is only one ten-thousandth of its body weight. On the other hand, although the human brain is one-sixtieth of its body weight, the mouses brain represents one-fortieth of its body weight. Despite these comparisons, elephants do not seem 10 times smarter than whales, and humans definitely seem smarter than mice.

What Are The Different Parts Of The Brain

The brain can be divided into the cerebrum, brainstem, and cerebellum:

  • Cerebrum. The cerebrum is composed of the right and left hemispheres. Functions of the cerebrum include: initiation of movement, coordination of movement, temperature, touch, vision, hearing, speech and language, judgment, reasoning, problem solving, emotions, and learning.

  • Brainstem. The brainstem includes the midbrain, the pons, and the medulla. Functions of this area include: movement of the eyes and mouth, relaying sensory messages , hunger, respirations, consciousness, cardiac function, body temperature, involuntary muscle movements, sneezing, coughing, vomiting, and swallowing.

  • Cerebellum. The cerebellum is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.

More specifically, other parts of the brain include the following:

Assembling A Brain In The Laboratory

The

Hebbian synapses have also been demonstrated in another kind of laboratory, where computer scientists and engineers have built them into a computer chip. The device is a simple one, with only 16 synapses, but it performs Hebbian learning quite efficiently, at the rate of a million times per second. Newer chips have already been developed to represent more realistic neurons, with many thousands of synapses and technology to represent the connections between such neurons will make the assembly of something more nearly resembling a working brain a little easier to envision. Such a device will have to combine analog signals, like those propagated within neurons, and digital signals, the off or on impulses transmitted from one neuron to another. It will not be simply a larger, or even an unbelievably faster, version of today’s familiar computer.

The field of artificial perception already boasts chips developed at the California Institute of Technology that are capable of much of the sensory processing performed just outside the brain by the retina, for example, and by the cochlea, the spiral passage of the inner ear whose hair cells respond to vibrations by sending impulses to the auditory nerve. Now in development as well are chips to simulate some of the functions of the visual cortex others, with some of the memory-storing capacity of the hippocampus, are being scaled up, closer to the dimensions of a living system.

What Are The Parts Of The Brain

Every second of every day the brain is collecting and sending out signals from and to the parts of your body. It keeps everything working even when we are sleeping at night. Here you can take a quick tour of this amazing control center. You can see each part and later learn what are involved with different tasks.

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.

How Do Conditions Of The Brain Affect Us Emotionally

Feelings of sadness, frustration and loss are common after brain injury. These feelings often appear during the later stages of recovery, after the individual has become more aware of the long-term situation. If these feelings become overwhelming or interfere with recovery, the person may be suffering from depression.

What Part Of The Brain Decides In A Quick Response

How to learn major parts of the brain quickly

The brain amygdala is responsible for recognition and rapid response to threatening or dangerous stimuli. In parallel, the nucleus accumbens, which is the brains reward system, is stimulated and leads to seeking pleasant activities, such as immediate responses.

Finally, the prefrontal cortex allows you to evaluate and control instinctual desires based on experience and specific context. In this way it can manage the activation of the amygdala, modulate the emotional response and, furthermore, evaluate the activation of the nucleus accumbens by weighting the weight of the gain.

Concomitantly, it inhibits impulsive behavior because it is in charge of reasoning, that is, of weighing the real danger of the situation, the short and long-term consequences, the potential benefits, etc.

Functions Of The Cortex

When the German physicists Gustav Fritsch and Eduard Hitzig applied mild electric stimulation to different parts of a dogs cortex, they discovered that they could make different parts of the dogs body move. Furthermore, they discovered an important and unexpected principle of brain activity. They found that stimulating the right side of the brain produced movement in the left side of the dogs body, and vice versa. This finding follows from a general principle about how the brain is structured, called contralateral control, meaning the brain is wired such that in most cases the left hemisphere receives sensations from and controls the right side of the body, and vice versa.

Just as the motor cortex sends out messages to the specific parts of the body, the somatosensory cortex, an area just behind and parallel to the motor cortex at the back of the frontal lobe, receives information from the skins sensory receptors and the movements of different body parts. Again, the more sensitive the body region, the more area is dedicated to it in the sensory cortex. Our sensitive lips, for example, occupy a large area in the sensory cortex, as do our fingers and genitals.

Ventricles And Cerebrospinal Fluid

Deep in the brain are four open areas with passageways between them. They also open into the central spinal canal and the area beneath arachnoid layer of the meninges.

The ventricles manufacture cerebrospinal fluid, or CSF, a watery fluid that circulates in and around the ventricles and the spinal cord, and between the meninges. CSF surrounds and cushions the spinal cord and brain, washes out waste and impurities, and delivers nutrients.

Gene And Protein Expression

Bioinformatics is a field of study that includes the creation and advancement of databases, and computational and statistical techniques, that can be used in studies of the human brain, particularly in the areas of gene and protein expression. Bioinformatics and studies in genomics, and functional genomics, generated the need for DNA annotation, a transcriptome technology, identifying genes, their locations and functions.GeneCards is a major database.

As of 2017, just under 20,000 protein-coding genes are seen to be expressed in the human, and some 400 of these genes are brain-specific. The data that has been provided on gene expression in the brain has fuelled further research into a number of disorders. The long term use of alcohol for example, has shown altered gene expression in the brain, and cell-type specific changes that may relate to alcohol use disorder. These changes have been noted in the synaptictranscriptome in the prefrontal cortex, and are seen as a factor causing the drive to alcohol dependence, and also to other substance abuses.
