The human cerebral cortex is the outermost layer of the brain.It is the most important area of the human brain.Even though the current technology knows very little about the human cerebral cortex.However, it is found that several cortical regions are functionally unique.These clearly identified areas will be discussed in the center.Most other areas may have a variety of complex features that are not unique or specific.
Main motor area-
It is located in the central front of the brain.It is located in front of the big central ditch known as the central ditch.The anterior central area of the brain can be divided into the back or front.The primary sports area is located in the back potion of the central front.In addition, it extends to the upper boundary and enters the secondary center leaflet.

Perform separate movements in different parts of the body.To this end, it receives a large amount of incoming fibers from the pre-motor area, sensory cortex and mound, basal and cerebral nuclei.It is the last station to convert the motor design to action (perform action.

The pre-motion area is wider than below and narrowed down to the front of the central front.It is located at the front of the body cortex.
This region accepts a variety of inputs from the sensory cortex, mound, and basal cortex.
The function is a stored program for motion activities.In addition, it is also related to the basal section to control rough posture movements.

Extend from the facial area of the central front back to the area of the middle back.It connects to extra eye muscles through the superior Hill.
The frontal eye field is considered to be a voluntary scan movement that controls the eye independently of visual stimuli.

Words are formed by connection with adjacent primary motion areas.Ensure proper stimulation of the muscles of the throat, mouth, tongue, soft jaw and respiratory muscles.
It is located in the lower forehead.

The prefrontal cortex is a wide area located at the very front (forehead) of the brain.It has a great connection with other cortical areas, including Qiu, Qiu Xiqiu and Parkinson's disease.In addition, the anterior brain fiber connects the small brain Bridge through the nucleus of the brain Bridge.The Lianhe fibers of Callosum connect the two anterior cortex together.

In fact, the prefrontal cortex seems to make us human.

Primary sensory area
This occupies the center of the outer hemisphere of the brain and the back of the medial central side leaflet.It receives sensory projection fibers from the VPL and VPM cores of the mound nucleus.The feeling of the throat, throat and perineum enters both sides of the cortex.The other side represents the other area.
Sensory Association area
Occupy the upper Parietal leaves extending to the inner surface of the hemisphere.It has many connections to other sensory areas of the brain.
It receives and integrates various sensory patterns.It helps to identify objects placed on hand without visual stimulation.

The primary View area is located at the back of the calcarine ditch.It is usually thinner than the rest of the cortex.
The visual cortex receives incoming fibers from the lateral knee-like body.The visual cortex also receives fibers from the temporal half part of the suffering side retina and the nasal half of the opposite side retina.In addition, the upper quadrant (lower field of view) on the retina passes through the upper wall of the calcarine ditch.

) Is passed to the lower wall of the calcarine ditch.
Rash is the central part of the visual cortex, accounting for 1 out of 3 of the visual cortex.A visual pulse from the peripheral part of the retina terminates in a concentric circle in front of the pillow.The visual cortex is receiving raw visual stimuli from the retina.

This area revolves around the main visual areas of the inner and outer surfaces of the hemisphere.Receive pulses from area 17 (visual cortex) and other cortical regions as well as the mound.The function is to link past experiences with impulses received from major visual areas.

It is considered to exist in the second visual area.The function is to move the reflex to move the eyes.In contrast, the eye area is responsible for voluntary eye movements.
Auditory area


The primary auditory region is located on the lower wall of the lateral groove.The projection fibers to the auditory cortex appear mainly in the medial knee-like body and form the auditory radiation of the inner sac.The front is responsible for receiving low frequency sound.High-frequency sound is the responsibility of the rear.Unilateral damage to the primary auditory cortex leads to partial hearing loss in the ears.However, there are signs of deafness in the opposite ear.This is because the medial knee-like body receives fibers mainly from the opposite organs of the corti.

It is located at the rear of the lateral groove and the primary auditory area of the upper back.Secondary auditory regions receive supply from primary auditory regions and hills.Its function is to explain the original sound received from the ear.In addition, the Association of auditory information with other sensory information is also important.

It is located in the dominant left hemisphere.It is mainly located on the forehead.It extends to the top leaf area around the back end of the side ditch.This area of the cortex is connected to the broca CUCs area and has nerve fibers called bow bundles.In addition, it also receives fibers from the visual cortex, auditory cortex.The Wernickes area allows for the understanding of written and oral language and allows one to read sentences, understand sentences and speak sentences out loud.This is a very important area of the cortex, where the body, vision, and hearing are combined.
