The Mind and Brain Functions and Physiology
The most important fact is that the brain is the organ of the mind and the mind is like the software of a computer. The mental functions are related to the cerebral cortex of the brain. In humans the cerebral cortex is better developed than the inferior animals. Our sense organs are like input devices of a computer. Our brain processes and stores the data in encapsulated form with respect to attributes. Our ears transmit sound signals to our brain, which are analyzed by our mind and classified as noise, vocal audio and music. Music files are further categorized as per specific attributes and stored in our brain. Whenever we listen to the same sound again we could easily name a person as per tonal quality of voice, instrument as per the pitch and rhythm of the music and the birds and animals as per their specific vocal attributes. Human mind is capable of distinguishing a variety of fragrances and odors, human faces and pictures, fonts and shapes, smooth and rough surfaces, bitter, sweet or sour tastes etc. Expressions of thoughts and emotions are special functions of our mind.
The brain, like other organs is powered by chemicals. Whenever the chemistry of brain is disturbed, mental symptoms are an early result. The glucose and oxygen have a vital role in the physiology and bio-energy generation of our body. The anoxia (low oxygen supply) of airmen and in the early stages of anesthesia may lead to chock. The hypoglycemia in diabetics on insulin therapy has been known to cause insulin shock or hypoglycemic shock. Certain groups of chemicals or drugs can cause mental disturbance and there are other chemicals or drugs which are capable of improving the mental function. For example hallucinogens like LSD disturb the mental functioning of normal people whereas tranquilizers and psychic energizers are known to improve the mental functioning of abnormal people. Except the numerical ability, the human mind and brain are faster than any computer in answering a variety of questions related to memory and experiences. Till date no computer could store the attributes of taste, smell, feelings and emotions. The super programming and coding of our mind is updated every moment through our observation and experience.
