What is the brain hemisphere?
The brain can be divided into two areas. The brainst is part of the brain extending down towards Misha. Cerebral hemispheres contain a wrinkled outer layer of brain, called the cortex and several deeper structures, including basal ganglia, hippocamp and amygdaloid core.
The cerebral hemisphere consists mainly of a perverted gray mass with an inner layer of white matter. The gray mass of the brain contains neural cell bodies. On the other hand, white matter is white because it contains myelinated axons that range from the body of neural cells. Gray mass stinks are called gyri and grooves are called sulci or cracks. The central sulcus is one of the most important sulci that separates the precentral and postcentral gyri. Precentral gyrus is connected to motor functions, while postcentral gyrus controls the sensory input.
Each brain hemisphere can be divided by four lobes, each with different functions. The frontal lobe that covers the area behind the forehead and the upper part of the head is involved in the PLarranging and movement. The parietal lobe, located just behind the frontal lobe, manages sensory information. The occipital lobe at the skull base is involved in the vision and temporary lobe, which lies on the side of the brain behind the ears, controls hearing.
Cerebral hemispheres are controlled by the contrastral sides of the body, which means that the right brain hemisphere controls the left side of the body and vice versa. For example, sensory information from the right hand goes to the left brain hemisphere where it is processed. To move with the right hand, the signal must come from the left side of the brain and cross again.
A large bundle of nerves called corpus callosum connects the left and right brain of the hemisphere. Both hemispheres are not always completely symmetrical and can be somewhat specialized. For example, the Wernicke region and the Broca region, the two parts of the brain involved in speech, are located on the left brain hemisphere.
deeper parts of the brain hemisphere JSou also decisive for the functioning of the brain. Basal ganglia, a collection of cores closely associated with bark, regulate the movement of the engine. Hippocampus is connected to storage and search for memory. Amygdaloid cores control emotional reactions, especially emotions such as anger and fear.
