Cocaine is a central nervous system stimulant drug extracted from coca plant that causes a rush of positive feelings initially but that can lead to impulsiveness, agitation, and anxiety and can cause withdrawal symptoms of exhaustion and depression. It is a stimulant drug that increases the stimulation of dopamine synapses by blocking the re-uptake of dopamine by the presynaptic neuron
Cochlea is the structure in the inner ear containing auditory receptors. It is the snail-shaped, liquid-filled structure that contains the structures of the inner ear, the most important of which are the basilar membrane, the tectorial membrane, and the hair cells.
Cochlear amplifier is how movement of the outer hair cells in response to sound increases basilar membrane vibration and therefore amplifies the response of the inner hair cells.
