What are the centers of the brain and what kind of centers are the brains?

Central nervous. Including the brain and spinal cord. The cerebrum consists mainly of the cerebrum.

Diencephalic, brainstem, cerebellum.

The spinal cord is composed of gray matter, which contains nerve cells, and white matter, which contains upper and lower conduction tracts. The cerebral hemispheres are covered by the cerebral cortex, forming sulci and gyrus on the surface of the brain, and the white matter, basal nucleus, and lateral ventricles inside.

The two cerebral hemispheres are connected by the corpus callosum. The diencephalon is located between the two cerebral hemispheres and is the relay station where the brainstem connects with the cerebral hemispheres. The upper brainstem is connected to the diencephalon and the lower part of the spinal cord, and is divided into three parts: the midbrain, the pons, and the medulla.

The cerebellum is located in the posterior cranial fossa, on the dorsal aspect of the brainstem. The spinal cord is located in the spinal canal and is the part of the brainstem that extends downward.

The spinal cord gives rise to 31 pairs of spinal nerves, which are distributed to the limbs and trunk, and innervate the motor, sensory, and autonomic functions of the limbs and trunk under the command of the brain.

The brain is the main part of the central nervous system and is located in the cranial cavity. The human and mammalian brains are particularly well developed and can be divided into three parts: the brain, the cerebellum, and the brainstem. The brain includes teleencephalitis, diencephalon, midbrain, pons and medulla, and there are many nuclei and nerve centers concentrated by nerve cells, and a large number of ascending and descending nerve fiber bundles pass through to connect the brain, cerebellum and spinal cord, and connect all parts of the central nervous system as a whole in morphology and function.

The left brain controls the right side of the body, the right brain controls the left side of the body, the cerebellum controls the endocrine and nervous systems, the brain processes information, and the cerebral cortex is responsible for memory functions.

The brain is the higher nerve center of the human body.

Important cerebral cortical centers are:

Somatic motor center: the main nucleus is vertically located in the anterior part of the anterior gyrus and paralobules. The somatic motor center on one side manages the movement of the skeletal muscles in the opposite half of the body.

Somatic sensory center: mainly located in the posterior gyrus and posterior paralobules. The somatosensory center on one side receives the impulse of superficial and deep sensation in the opposite half of the body.

Visual center: cortex located on both sides of the lateral talar sulcus on the medial surface of the occipital lobe. The visual mid-range nerve center on one side receives visual impulses from the temporal half of the ipsilateral retina and the nasal half of the contralateral retina.

Auditory center: located in the transverse temporal gyrus. Each auditory center receives auditory impulses from both ears.

Language center: There are four main ones: the motor language center (speech center), located posterior to the inferior frontal gyrus; Writing center, posterior to the middle frontal gyrus; the visual language center (reading center), located in the angular gyrus; The auditory language center (observance center) is located in the superior marginal gyrus.

Olfactory Center: Modified stupid is located near the hook next to the hippocampus.

Visceral activity center: generally considered in the limbic lobes.

The brain is the highest part of the nervous system, consisting of two cerebral hemispheres, the left and the right, and there are horizontal nerve fibers connected between the two hemispheres. Each hemisphere includes: The cerebral cortex (cerebral cortex): is a layer of gray matter (the concentrated part of the cell body of nerve cells) on the surface.

The surface of the human brain has many concave sulcus (fissures) with a raised gyrus between the sulcus (fissures), thus greatly increasing the area of the cerebral cortex.

The human cerebral cortex is the most developed, it is the organ of thinking, which dominates all the activities in the body and regulates the balance between the body and the surrounding environment, so the cerebral cortex is the material basis for high-level neural activities.

The importance of the brain

The key to the fact that human beings are able to understand the world, transform the world and become the "spirit of all things" is that human beings have excellent thinking ability and memory ability. Memory is an essential characteristic of human physiological and mental activities. Life is full of vitality and creativity, and all vitality and creativity are inseparable from the source of memory.

If you lose your memory, your behavior will inevitably lose your vitality and creativity, and you will even lose many of your "instinctive" skills, and it will be difficult for you to live. It is this ability to memorize that makes people full of spirituality and vitality.

The brain is divided into four main functional areas, with the left hemisphere innervating movement on the right side of the body.

2.The right brain controls the left side of the body.

3.In the human brain, the left hemisphere is more focused on managing speech function,4The right hemisphere brain focuses on functions such as managing spatial concepts.

Sensory center, auditory center, motor center, visual center.

Sensory area, motor area, speech area, joint area.

The brain is mainly composed of nerve cells in the human body, and the edges of each nerve cell have several outward protruding parts, called dendrites and axons.

The human brain is the main component of the human body, and it helps people remember everything. At the end of the axon there is a bulging protrusion called a synaptosome. The synaptosomes of each neuron are in contact with the dendrites or axons of another neuron. This structure is called a synapse.

Neurons communicate with other neurons through "synapses" and receive information from many other neurons. How many synapses are there on each neuron? Some estimates suggest that there are an average of 30,000 synapses per neuron in the human cerebral cortex.

So, how many neurons does the human brain have? There are about 14 billion of them. The connection between the synapses of these 14 billion nerve cells is difficult to express in astronomical numbers.

The function of neurons to transmit and receive information is the physiological basis of the brain for memory. It is this structure that allows the brain to form a huge reservoir of information, and scientists believe that the human brain stores information equivalent to the content of a billion books. It can be seen that our brains have an infinite memory capacity. Cerebrum.
