Signaling in the basal ganglia: postsynaptic and presynaptic

Web14 Apr 2024 · The intensity of voltage spikes generated in the presynaptic neuron is modulated by the synapses and then summed up in the membrane capacitor of the postsynaptic neuron. Each postsynaptic neuron has synapse units consisting of excitatory and inhibitory parts to implement positive and negative weights, respectively (Figure 7b ). [ … WebSTDP is highly sensitive to the interval between the pre- and postsynaptic spikes; however, the role of STDP in generating timed responses remains unclear. If a presynaptic spike consistently occurs 25 ms before the postsynaptic spike, the synaptic strength between the two neurons will increase. mercy johnson fashion style
