What Are the Parts of the Brain?

The human brain is the most complex part of all organs, and the center of all nervous systems; although it looks like a whole piece, through the nervous system experts, you can understand its various functions. The human brain can be divided into three parts: the Central Core, the Limbic System, and the Cerebral Cortex. The brain nucleus is the process that governs human basic daily life, including breathing, heartbeat, awakening, exercise, sleep, balance, early sensory system, and so on. The brain system is responsible for functions such as actions, emotions, and memory processing. In addition, it is also responsible for body temperature, blood pressure, blood sugar, and other home activities. The cerebral cortex is responsible for the higher cognitive and emotional functions of the human brain. It is divided into two main blocks-the left brain and the right brain, each of which contains four parts-the frontal brain (Frontal Lobe), Parietal Lobe, Occipital Lobe, Temporal Lobe.

The main functions of the four brain lobes that make up the cerebral cortex are shown on the previous page. As for its main constituent cells, they are brain neurons. During the baby's growth in the mother's body, brain neurons will continue to increase, with an average increase of 250,000 brain neurons per minute. By birth, it can reach nearly 10 billion brain neurons; the weight has also grown from 100 grams to 1,100 grams. The speed is quite amazing. During this growth process, proper hearing, somatosensory, and visual stimulation will help the development of brain collagen nerve cells (Glial Cells). This is also the so-called preschool education for 0 to 3 years old, because it is human The most important stage of brain development. At this stage, the brain is doing the construction project (basic engineering) of the entire neural network of the brain.

The brain is located in front of the brainstem, and the left side is divided into left and right cerebral hemispheres by a longitudinal split of the brain. The surface of the cerebral hemisphere is covered with a layer of gray matter, called the cerebral cortex, whose surface is uneven to form the sulci (depression) and brain gyrus (bulge). The deep cortex is white matter, composed of various nerve fibers, and one lumen in each hemisphere, that is, the lateral ventricle and the cerebral cortex are the highest centers for the nervous system to regulate body movements. At the same time, it can also regulate visceral activity.
