What Are The Three Lobes Of The Cerebellum

What are the different parts of the brain and what do they do? | Cancer Research UK

The cerebellum’s hemispheres are each divided into three lobes: the anterior lobe, posterior lobe, and the flocculonodular lobe. These lobes are split up by two fissures , called the primary fissure and the posterolateral fissure.

The anterior lobe and the vermis together are known as the spinocerebellum. The spinocerebellum helps regulate muscle tone and body movement. It’s also responsible for our sense of our body’s position in relation to our surroundings, and in relation to other parts of our body . This area receives input from our spinal cord, auditory and visual systems.

Information Transport And Boundary Assistants

The gyrus and sulcus are what give the brain its wrinkly appearance. The grooves of the brain are known as the sulci, while the bumps are called the gyri. These folds and ridges help increase how much of the cerebral cortex can fit into the skull. They also create boundaries between the different sections of the brain, such as the two hemispheres and four lobes of the cerebrum.

The Architecture Of The Brain

The brain is like a committee of experts. All the parts of the brain work together, but each part has its own special properties. The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain.

The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum . The hindbrain controls the bodys vital functions such as respiration and heart rate. The cerebellum coordinates movement and is involved in learned rote movements. When you play the piano or hit a tennis ball you are activating the cerebellum. The uppermost part of the brainstem is the midbrain, which controls some reflex actions and is part of the circuit involved in the control of eye movements and other voluntary movements. The forebrain is the largest and most highly developed part of the human brain: it consists primarily of the cerebrum and the structures hidden beneath it .

When people see pictures of the brain it is usually the cerebrum that they notice. The cerebrum sits at the topmost part of the brain and is the source of intellectual activities. It holds your memories, allows you to plan, enables you to imagine and think. It allows you to recognize friends, read books, and play games.

What Are The Main Parts Of The Brain Stem

Alzheimer

The brain stem is made up of three parts: the midbrain, the pons and the medulla.

The midbrain is located underneath the cerebral cortex, near the top of the brain stem. It connects the cerebrum to the brain stem. The midbrain helps process visual and auditory information, such as controlling the eyes and eyelids. It also plays a role in regulating our body temperature and motor movements.

Pons is the Latin word for “bridge.” The pons is responsible for connecting the brain stem to the cerebral cortex and the cerebrum to the cerebellum. It can be found right underneath the midbrain and above the medulla oblongata. Although it is the largest section of the brain stem, the pons is only about 2.5 centimeters long. The pons is responsible for assisting in motor functions, particularly for nerves in the face, ears, and eyes. It also plays a role in regulating the intensity and frequency of breathing. It has both gray and white matter, but it does share gray matter with the midbrain. The reticular formation of the pons’ gray matter plays a vital role in dreaming and REM sleep.

How Does The Human Brain Work

If we want to know the brain and its functions, it is important to remember that this is an organ of the nervous system. This system is responsible for receiving and processing the information that comes from the outside environment. In addition, thanks to brain processing we can generate responses to information and external stimuli. If you want to know more, we recommend you read the following article on how it works in the nervous system.

Daniel Goleman in his book Emotional Intelligence has valued this expression of emotions and feelings of the human being. Well, the part of the brain that manages this emotional information is the amygdala located in the limbic system . Human beings can not only experience emotions from an external fact that acts as a stimulus to which we give an answer. An internal fact can also generate an emotional movement, for example, a thought. Well, the amygdala is an essential core of these processes.

Brain Myths Of Creativity #: Left Brain And Right Brain

Have you ever been asked if you are left brained or right brained ? This question refers to the idea that each hemisphere of the brain is specialized for different abilities. In general, the left hemisphere has been thought to specialize in understanding words, processing mathematical information, and thinking analytically . The right hemisphere, on the other hand, was thought to specialize in processing non-verbal information, spatial information, music, emotions, and creativity. As we see in creativity and other complex functions, a number of specialized structures in the brain work together to accomplish something. Localization of certain abilities to one side of the brain or the other was first found in certain individuals who had the main communication between their hemispheres, the corpus callosum, cut so that each hemisphere was essentially working independently. In most people, however, the two sides of the brain are able to communicate, so while brain structures may have some specialization, most complex brain functions require many parts of the brain working together.

  • People used to believe that the two sides of the brain were specialized for different activities: the logical left and creative right hemispheres. Retrieved from: .

The Science Of Hearing

The science of hearing – Douglas L. Oliver

The ability to recognize sounds and identify their location is possible thanks to the auditory system. Thats comprised of two main parts: the ear, and the brain. The ears task is to convert sound energy into neural signals the brains is to receive and process the information those signals contain. To understand how that works, Douglas L. Oliver follows a sound on its journey into the ear.

What Is A Stroke

What are the different parts of the brain and what functions do they control?

A stroke occurs when the supply of blood in the brain becomes compromised. This can happen by either a blood clot obstructing an artery and stopping blood flow to an area of the brain or an artery in the brain bursting and leading to bleeding inside the brain .

During a stroke, the affected areas of the brain do not receive enough oxygen-rich blood. As a result, brain tissue begins to die. Depending on the area of the brain affected by stroke, this damage will cause changes in certain sensory, motor, or cognitive functions.

Although its impossible to revive dead brain cells, recoveryis possible through neuroplasticity.This process allows healthy parts of the brain to take over the functionsdamaged by stroke.

The goal of stroke rehabilitation is to restore or compensate for the secondary effects sustained to your highest potential. These effects vary from person to person based on the size and location of the stroke.

Next, we will discuss the different areas of the brainaffected by stroke so that you can better understand what to expect.

What Happens In The Brain During Creative Thinking

So now that you know about three different types of creativity, insight, convergent thinking, and divergent thinking, you might think that the brain processes must be complicated. Previous research has demonstrated that several different thought processes in the brain, including processes called working memory, abstraction, planning, and cognitive flexibility, are all critical to creative thinking. This research has also shown that the ability to develop strategies is a key part of creativity . Neuroscientists , in their attempt to make a connection between creative thought processes and the parts of the brain that may process them, have defined creativity as requiring the mixing and remixing of mental representations to create novel ideas and ways of thinking If you look back to Steve Jobs quote, you will see that he describes creativity in a similar way. Combining and recombining mental representations is simply connecting things in the brain in the way that the brain stores information.

Where Is The Brain Located

The brain is enclosed within the skull, which provides frontal, lateral and dorsal protection. The skull consists of 22 bones, 14 of which form the facial bones and the remaining 8 form the cranial bones. Anatomically, the brain is contained within the cranium and is surrounded by the cerebrospinal fluid.

The Cerebrospinal Fluid is a fluid that circulates within the skull and spinal cord, filling up hollow spaces on the surface of the brain. Every day, the specialised ependymal cells produce around 500mL of cerebrospinal fluid.

The primary function of the CSF is to act as a buffer for the brain, cushioning mechanical shocks and dampening minor jolts. It also provides basic immunological protection to the brain.

Furthermore, CSF provides buoyancy for the brain. i.e., the brain is suspended in a layer of CSF, wherein, the weight of the brain is nearly negated. If the brain is not suspended in CSF, it would be impeded by its weight, consequently cutting off the blood supply in the lower half of the brain. It would lead to the death of neurons in the affected area.

What Are The Four Nuclei Of The Cerebellum

As the three lobes take in information from the cerebrum, spinal cord and body, the cerebellum also has a way of sending out information. This is done through what are called nucleia bundle or neurons embedded deep in the cerebellum’s white matter.

Rounding out cerebellum’s composition are the four nuclei that pass information between the cerebrum and the body. These nuclei are: dentate, emboliform, globose, and fastcgi. They receive on the body and give information from the cerebellum through Purkinje cells and mossy fibers.

The final section of the brain is a mass of tissue and nerves called the brain stem. Located underneath the cerebrum and cerebellum, the brain stem connects the brain to the spinal cord. All information that goes from the brain to the body , must pass through the brain stem to reach its destination. The brain stem accounts for the remaining 5% of the brain’s mass, and is , the oldest part of the brain. The brain stem is responsible for regulating the heart and lungs, communications between the brain and the peripheral nervous system , our sleep cycle, and coordinating reflexes.

The brain stem plugs the brain into the rest of the body through the spinal cord .

The Brain And Its Parts

What do the different parts of your brain control... well ...

Often, we use the term brain to refer to the enfecalo, the main organ of the central nervous system, the brain contains other parts such as the medulla and the cerebellum. Next, we are going to mention the most important parts of the brain:

  • One of the most important parts of the brain is the cerebellum, located in the brain, and its function is to regulate such important aspects of the organism as posture, balance, and coordination.
  • The hypothalamus regulates the functions of the organism, for example, sleep cycles, body temperature, hunger, and mood.
  • Language is one of the most characteristic expressions of the humanity of the person. Well, the parts of the brain that regulate speech are Brocas area and Wernickes area . In this other article, you can find more information about the area of Broca and Wernicke.
  • The hippocampus is a brain area that promotes the storage of memories and learning.

Next, we show you an image to give you an idea of how a real human brain works and what its parts are.

The National Institute Of Neurological Disorders And Stroke

Since its creation by Congress in 1950, the NINDS has grown to become the leading supporter of neurological research in the United States. Most research funded by the NINDS is conducted by scientists in public and private institutions such as universities, medical schools, and hospitals. Government scientists also conduct a wide array of neurological research in the more than 20 laboratories and branches of the NINDS itself. This research ranges from studies on the structure and function of single brain cells to tests of new diagnostic tools and treatments for those with neurological disorders.

Creativity In The Brain

Recently, the ways we think and the parts of the brain that contribute to creativity have become of interest to cognitive neuroscientists. Since creativity is among one of the most complex of human behaviors, it likely requires the coordination of multiple brain regions and types of thinking. Because creativity is so complex, it seems naive to think that creativity can be localized to a single region in the brain. In fact, only a few neuroscience studies have tried to investigate the regions of the brain responsible for creativity. For a long time, scientists thought that creativity was processed only in the right hemisphere of the brain. However, studies that looked at the activity in the brain while people were doing creative tasks, or in patients who had brain damage that resulted in difficulty with creativity showed that an area of the brain called the frontal cortex was associated with creativity. This seemed to make sense because the frontal cortex processes the previously mentioned cognitive processes .

What Is The Brain And Why Does It Matter

What Do the Different Parts of the Brain Control?

The brain is a three-pound organ that serves as headquarters for our bodies. Without it, we wouldn’t be able to process information, move our limbs, or even breathe. Together with the spinal cord, brain structure and function helps control the central nervous systemthe main part of two that make up the human nervous system. The human nervous system is responsible for helping us think, breathe, move, react and feel.

Like any good command center, there is a structure to the brain and its operations that help it carry out its basic functions.

Of all the human body systems, the nervous system is the most complicated system in the body. The brain is the central part of the nervous system. It is an intriguing organ, that has been studied right from the time it develops in the fetus. The human brain weighs about 1.5 kg in adults. The cerebrum, which forms the bulk of this organ, is divided into two hemispheres, the right hemisphere and the left hemisphere.

There are many ways of dividing the brain for studying its various aspects. However, it is conventionally divided into three parts: the forebrain, the midbrain and the hindbrain. The brain also contains four interconnected cavities called ventricles, which contain cerebrospinal fluid. We will study the diagram of the brain and its functions in this article, along with a detailed study of the brain anatomy.
