Brain Hardware consist of anatomy and physiology of the brain; where is subjected to the physical and chemical (Pour Science) role and regulation. Obviously, we are not going to present huge body of these two main disciplines here; and are necessary neither.
To show the importance of brain health as well as becoming aware of the brain, main functional structures listed here. Detail will come elsewhere; and last copy of Gray’s Anatomy, Guyton Textbook of Physiology, and/or Principles of Neual Science (Eric R. Kandel, J. H. Schwartz, and T. M. Jessell) recommended for young scientists who interested to gain further knowledge.
Hardware of brain consists of millions of tiny cells so called neuron. This gelatinous organ weight about one kg; and located in the skull. Neurons as an excitable cell appear in different shapes and kind (sensory, motor, and interneuron); and consist of cell body and processes so called Dendrites and Axons.
Neuron has ability to be stimulated; and transmits nerve impulse (action potential) from dendrites and cell body to the axon. Impulse then pass through the synaptic cleft via neurotransmitters such as acetylcholine, serotonin, noradrenalin, dopamine, GABA, endorphin, etc.; and either stimulate or inhibit the next neuron.
Synapses located in the gray matter; and form the processing centers. White matter considered as pathway; and consists of nerve process. Brain hardware receives information from the surrounding environment all over the life spine; synapses have an important role in the processing of these information.
Brain consists of cerebellum and cerebrum; and cerebrum itself forms brainstem, limbic system, and thalamocortical structure. Cerebellum is dealing with equilibrium, and skill of the movements. Vegetative functions of the body such as digestion, respiration, and circulation are managed by brain stem.
Limbic system is dealing with emotion, and motivation; whereas thalamocortical system with sensation, perception, cognition, as well as motor functions of the body including language. Limbic system has an important role in learning via hippocampus; and memory storage located in the Thalamocortical system.
