Postsynaptic terminal function
WebAction potentials are the fundamental units of communication between neurons and occur when the sum total of all of the excitatory and inhibitory inputs makes the neuron’s membrane potential reach around -50 mV (see diagram), a value called the action potential threshold. Neuroscientists often refer to action potentials as ‘spikes’, or ... WebThe postsynaptic density ( PSD) is a protein dense specialization attached to the postsynaptic membrane. PSDs were originally identified by electron microscopy as an …

Transport proteins; Trafficking proteins; How The Axon Terminal Works. Once the central nervous system (brain and spinal cord) sends an impulse, it sets in motion a “chain-reaction,” whereby the preceding neuron “tags” the postsynaptic neuron, perpetuating the nerve impulse.. The …
WebThe simultaneous discharge of multiple presynaptic terminals is needed to excite the postsynaptic neuron. It occurs via the process of summation. Inhibitory Postsynaptic Potential. A decrease in the resting membrane potential of the postsynaptic neuron due to synaptic transmission is called inhibitory postsynaptic potential.
