Cerebral cortex: what it is, function and location (2023)

Cerebral cortex: what it is, function and location (1)

What is the brain cortex?

Your cerebral cortex is the utmost layer of yoursBrainThis surface has many wrinkles that give it a wrinkled look.The wrinkles consist of many deep grooves, which are referred to as grooves and high areas.These wrinkles increase the surface of your brain and enable large amounts of information to be processed.More nerve cells.The cerebral cortex is about half of the total mass of your brain.

Its cerebral cortex consists of six layers of nerve cells that contain between 14 and 16 billion nerve cells.There are two millimeters (mm) up to four mm (0.08 inches at 0.16 inches).

His cortex is divided into four wolves: frontal, parietal, temporal and occipital.Each of these wolves is responsible for the processing of different types of information., Argumentation, thinking, learning, decision -making, emotion, intelligence and personality.

Why is the brain bark called Gray Matter?

The gray substance found in the outer layer of your brain is found cover material called Myelin.

The white substance in its brain consists of axon packages, the long central section of a nerve cell that is involved in Myelin.The myelin gives the fabric its whitish color.

What is the difference between the brain cortex and the brain?

Your brain bark is the outer layer on the top of your brain.Your brain is the largest area of your brain.Your brain shares your brain in two hemispheres, which are referred to as hemispheres.The hemispheres are referred to by a package of nerve fibers, the Corpus Corpus Calosum names.Caloso Corpus enables her two hemispheres to communicate.

What is the Neocortex?

Most of its brainrinal is viewed as a neocortex.

What are the functions of the brain cortex?

Your brain bark is involved in many functions with a high level, such as reasoning, emotions, thinking, memory, language and consciousness.

Frontal lobes functions

YourFrontallappenIt is in front of her brain behind her forehead.The functions of your frontal appeal include:

  • Decision -making, problem solving.
  • Conscious thoughts.
  • Attention.
  • Emotional and behavioral control.
  • Language production.
  • Personality.
  • Intelligence.
  • Body movement.

The special class areas in this wolf are the motorcortex, the prefrontal cortex and the drill area.Motorcortex is responsible for the body movement.SEU prefrontal cortex is responsible for "executive functions" and leads other areas of your brain.The drilling area is part of your frontal apparatus, which is involved in language production.

Occipital wolf functions

YourLobo -OccipitalIt is on the back of your brain.The functions of your occipital wolf include:

  • Visual processing and interpretation.
  • Collection of visual data on color, movement and instructions.
  • Object and face recognition.
  • Perception of depth and distance.
  • Mapping of the visual world.

Parietal wolf functions

YourLobo parietalIt is located between the front and the occipital rag and over the temporal lobe.The functions of your Parietal wolf include:

  • Sensory information (touch, pressure, pain, position, vibration, temperature) processing.
  • Spatial processing and spatial manipulation.This is the ability to understand where they are in the three -dimensional space, e.g.B. in your home or your city.

Special class areas in this wolf are the somatosensory cortex.Get sensory information ("feeling" information) of your entire body.Here is an example of how brain wolves work together:

The motorcortex on the front lobe of your brain sends the message that directs the muscles on the arm and hand to reach a cup of the kitchen table.Including the assessment of your temperature.Space processing on your Parietal Wolf enables you to buy the glass, to buy the glass to search, to search the glass removal from hand to cup from the table and other surrounding objects.

Temporal lobes functions

YourLobo temporalIt is located between the front and occipitall raps and under their parietal lob.The functions of your temporal lobe include:

  • Understanding of language, language education, learning.
  • Storage.
  • Hear.
  • Nonverbale Interpretation.
  • Sound image conversion in visual.

A special note area in this wolf is the Wernicke area.It has recently been found that this area is involved in languages and sounds based on language and connects it with the previously learned sounds.

What are the areas of the brainrinal?

Some researchers otherwise look at the brain and classify the areas of the brain bark according to the three main types of functions: sensory, motor and associated areas.

Sensory areas:These areas of your brain cortex get sensory information from your senses and your surroundings.The functions include:

  • Existing visual information and object recognition.These functions are referred to by an area of your occipitall loaf, which is called Cortex Visual.
  • Evaluation of touch information, temperature, position, vibration, pressure and pain of your body.These functions are processed by an area of their parietal wolf, which is referred to as somatossensoric cortex.
  • Processing of listening information.This function is referred to by an area of its time lobe, which is referred to as the auditorial cortex.
  • Processing of taste and taste.These functions are referred to by an area of their frontal apparent.

Motor areas:These areas of your brain cortex are involved in the voluntary muscle movement.These functions are mainly processed by their frontal lobes.The functions include:

  • Coordination of the muscle movement.
  • Planning of complex movements.
  • Learning through imitation and empathy.

Association areas:These areas are distributed in all four rags and connect and give the functions complexity.The functions include:

  • Organize and provide information from sensory and motor areas.
  • Personality and control of emotional behaviors.
  • Spatial awareness and argument.
  • Storage processing.
  • Think visually and keep the visual memories.
  • Create visual information with memories, sound and language.

How can the crew of the brain be damaged?

The damage to any area of your brain rest usually results from tumors, trauma, autoimmune diseases or a cerebrovascular accident (brain bleeding or stroke).

What are the symptoms of a damaged brain cortex?

The symptoms depend on the damaged area of cerebral cortex.

Front lobe

The symptoms of damage or injuries to your frontal appeal include:

  • Storage problems.
  • Changes in personality.
  • Troubleshooting problems and decision problems.
  • Attention problems.
  • Emotional deficit, socially inappropriate behavior, behavior changes.
  • Lack of ability to understand or express language (Aphasia).
  • Talking difficulties (apraxia).
  • Weakness, paralysis, muscle loss of control on one side of the body (flabby hemiplegia).

An additional cause of damage to the frontal lobes is dementia.

Violation of the Parietal Wolf

The symptoms of damage to your parietal wolf include:

  • Storage generation.
  • Problems to write or not write (agraphia).
  • Difficulties with mathematics.
  • Deafness.
  • Disorientation.
  • Bad eye -ye coordination.
  • Inability to only identify objects of contact (astereognose).
  • Loss of sensation.
  • Aphasia.
  • Inaction.

Lesion in the temporal rap

The symptoms of damage to your temporal lobe are:

  • Hearing difficulties.
  • Storage problems.
  • Difficulty to recognize faces and objects.
  • Language defects (like Wernicke aphasia), difficulties in understanding language.

The additional causes of damage to temporal lobes include epileptic seizures, development dyslexia and Alzheimer's disease.

Occipitall hurt injury

The symptoms of damage to your occipital wolf include:

  • Difficulties to realize more than one object at the same time.
  • Problems, objects to see.
  • Color blindness.
  • Hallucinations with vision.
  • Total blindness.

A note from the Cleveland Clinic

Your crew is the external cover of the surface of your brain.There is between 14 and 16 billion nerve cells, consciousness and functions in connection with their senses.
