cerebral cortex function

Brain Anatomy: Cerebral Cortex Function

The cerebral cortex is connected to various subcortical structures, such as the thalamus and basal ganglia, by sending information to them via efferent connections and receiving information from them via afferent links. Most sensory information is directed to the cerebral cortex function through the hill.

 

However, information on the sense of smell goes through the olfactory bulb to the olfactory cortex (piriform bark). Most connections come from one area of the cerebral cortex, not from subcortical areas;

 

Areas of the senses| cerebral cortex function

Sensory areas are areas of the cerebral cortex that receive and process information from the senses. Generally, two hemispheres receive information from the opposite (opposite) side of the body. For example, the correct primary somatosensory cortex receives information from the left limb, and the correct visual cerebral cortex function receives information from the left field of view.

 




 

In cerebral cortex function, The organization of sensory maps in the cortex reflects what is with the appropriate sensory organ in the so-called topographic map. Adjacent points in the main visual cortex correspond, for example, to neighboring retinal points.  In the same way, there is a tonotopic map in the primary auditory cortex and a somatotopy map in the primary sensory cortex.

 

 Areas with a lot of sensory innervation, such as the tip of the fingers and lips, require more area of the cerebral cortex function to process a more delicate sensation.

 

 

Motor areas

They are in the shape of a pair of headphones extending from ear to ear. Motor zones are very closely related to the control of voluntary movements, especially minor fragmented movements performed by hand. The right half of the motor area controls the left side of the body and vice versa.

 

 

Two areas of bark are commonly referred to as motor:

Primary motor cortex that performs voluntary movements [source needed]
Additional motor areas and pre-bark, which select voluntary movements. [Needed source]
In addition, the engine functions are described for:

 

 

Parietal cortex, which directs voluntary movements in space
The dorsolateral prefrontal cortex, which decides which voluntary movements to follow according to higher-order instructions, principles, and thoughts generated by itself.
Just below the cortex are connected subcortical masses of gray matter called basal ganglia (or nuclei). The basal ganglia receive data from the substantia nigral region of the midbrain and motor cortex and send signals back to both locations. 


 

The main components of the basal ganglia are the caudate nucleus. The crust, pallidus globus, the substantia nigra, the nucleus accumbens and the hypothalamic nucleus.

 

Association zones

IN the cerebral cortex function, The areas of association are parts of the cerebral cortex that do not belong to the primary regions. They function to create a sensible perceptual experience of the world, enable us to interact effectively and support abstract thinking and language. The parietal, temporal and occipital lobe – all located in the back of the bark – integrate sensory information and information stored in memory. 

 

Each network connects dispersed areas in widely spaced cortical regions. Separate networks are adjacent to each other, creating a complex series of interwoven networks.

Newer research suggests that language expression and reception processes occur in areas other than those around the lateral fissure, including the frontal lobe, basal ganglia, cerebellum, and bridges. 

 

The thin layer of the brain

The cerebral cortex is a thin layer of the brain that covers the outer part (1.5 mm to 5 mm) of the brain. The bark is gray because the nerves in this area do not have isolation that makes most of the other parts of the brain appear white. The bark also includes the cerebellum.

The cerebral cortex function consists of curled ridges called gyri, which form deep sulcus or fissures called sulci.

The brain is the most developed part of the human brain and is responsible for thinking, perceiving, producing and understanding the language. Most information processing occurs in the cortex. These lobes include the frontal lobes, parietal lobes, temporal lobes, and occipital lobes.

 

 The cerebral cortex participates in several functions of the body, including Determining intelligence identifying personalityMotor functionsPlanning and organizationTouch SensationProcessing sensory informationLanguage processing.

 

The cerebral cortex contains sensory areas and motor areas. Sensory areas receive input from the hill and process sensory information. These include the visual cortex of the occipital lobe. The auditory cortex of the temporal lobe, taste bark and somatosensory bark of the parietal lobe. Within sensory areas, there are areas of association that give sense to sensations and associate sensations with specific stimuli. Motor areas, including the main motor cortex and pre-motor cortex, regulate voluntary movements.

 

 

Location of the cerebral cortex

Directionally, the brain and the bark that covers it are the highest part of the brain. It is better than other structures such as bridges, cerebellum, and prolonged core.

 

Disorders of the cerebral cortex
Many disorders result from damage or death of cerebral cortex brain cells. The symptoms appear to depend on the damaged area of the bark.  People may have difficulty walking, can not dress or cannot use common items properly.

 

Damage to the parietal lobe of the cerebral cortex can cause a condition called agraphia. These people have difficulty writing or are unable to write. Damage to the cerebral cortex may also result in ataxia.
