Brain with all its neurons, and neural functions transcribe to thinking and vocal formation. A small region of brain contains millions of neurons and their communication coordinate the overall activity of brain, our thinking, our memory, our speech and so on. Each neuron is a single cell with a central body from which numerous fibers protrude, dendrites, axons. These fibers make transmission lines. The neural network has 3 basic building blocks. a) information transfer, b) the assimilation and translating these information into action like memory, descision making and other activities., c) the synapses (junctions where inter connections meet) aid the sensory tasks such as processing visual stimuli,while the motor tasks control the movement and the decision making by which the sensory nerves derive the motor tasks.

The fundamental components of the brain are 1) Telencephalon, 2) Diencephalon, 3) Mesencaphalon, 4) Mycelencaphalon, and 5) Metencaphalon. Epigenetic regulation of neural gene expression and their on the neural functions are essential for the development of functions of the CNS. This mechanism and include the DNA methylation, histone modification and the chromatin remodeling events that mediate the preplanned gene regulation. The study is quite complex and the research in on for the behavior and other motor functions as to how the brain derive them and control those actions.
