WebFigure 12.27 The Synapse The synapse is a connection between a neuron and its target cell (which is not necessarily a neuron). The presynaptic element is the synaptic end bulb of the axon where Ca 2+ enters the bulb to cause vesicle fusion and neurotransmitter release. Web16 mrt. 2012 · Scheme of shared post synaptic signaling pathways leading to LTP and LTD - "Molecular Mechanisms in Synaptic Plasticity" ... The neuronal membrane is equipped with several types of ion channel and ion pump proteins which enable it to conduct nerve impulses in the form of electrochemical signals called action potentials.
