WebIn lithic reduction, termination type is a characteristic indicating the manner in which the distal end of a lithic flake detaches from a core (Andrefsky 1998:18). Common types … WebThat action must be terminated in order for proper neuronal communication to continue. This is accomplished mainly through two processes: neurotransmitter transport and/or degradation. Transport physically removes the neurotransmitter molecule from the synaptic cleft. Degradation breaks down the neurotransmitter molecule by enzyme activity.
