A mammal’s BRAIN in comparison to a bird of same body mass / size is twice & ten times to a reptile.. Not only in size but the Cerebral Cortex is very different in shape in comparison to birds or reptiles or other than mammals.. There is a major difference in PRE-FRONTAL or SUPERIOR FRONTAL which plays a major role in behavioural issues..

Our BRAIN functions almost totally depend on transmission & responding of electromagnetic / chemical signals transmit by the neurons to other cells through Synapses..

Our BRAIN generates a electromagnetic field which can be detect outside BRAIN through modern technology.. This electromagnetic field create by tissues / fibres through electro chemical process done by neurons for working / signalling..

A major role also played by Glial Cells to control the chemical characteristics of fluid that surrounds the neurons in our BRAIN..

Our BRAIN consumes a lot more energy of our body in proportion of its size.. The brain typically gets most of its energy from oxygen-dependent metabolism of glucose..
