Complex, or "higher," mental activity, such as thought, reason, and abstraction,[2] is consciously controlled.
The human brain is immense and complex. It contains some one hundred billion neurons,[1][2] which are capable of electrical and chemical communication with tens of thousands of other nerve cells.[1][2] Nerve cells in turn rely on some quadrillion (1015) synaptic connections for their communications.
