Basic Neuroanatomy and Normal Adult EEG

Merely weighing three pounds, the human brain executes complex functions from controlling the movements and sensation to language, emotions, and thoughts.

It is protected by skull, three meninges and cerebrospinal fluid. It is made up of two anterior-superior larger cerebral hemispheres and two posterior-inferior smaller cerebellar hemispheres (cerebrum). The deeper areas of the brain consist of thalamus, hypothalamus, basal ganglia, hippocampus, amygdala, and cingulate gyrus.

All these parts are not just interconnected but do communicate with each other via an extensive network of tracts. The brain is highly vascular and is supplied by an extensive network of arteries and veins. There are billions of cells in the brain; neurons-the electrically active cells and neuroglia-the supporting cells.

 EEG is generated by electrically active neurons, which have variable morphology (patterns) based on patients' clinical state and health. The brain activity during awake, alert, focused, and asleep states varies significantly.
