Figure 1. Diversity in the temporal synaptic properties of GABAergic interneurons.

Figure 1.

Inhibitory interneurons exhibit distinct temporal dynamics of both their synaptic inputs and outputs. A. Excitatory synaptic inputs to PV interneurons recruit these cells quickly but rapidly show synaptic depression. In turn, the inhibitory synapses from PV interneurons to excitatory pyramidal neurons (PN) likewise show synaptic depression. B. In contrast, excitatory inputs to SST interneurons require repeated activation and exhibit synaptic facilitation, resulting in delayed recruitment of spiking activity. However, SST synapses onto PNs show little synaptic depression. C. The short-term plasticity of excitatory synapses onto VIP interneurons and from VIP interneurons to PNs remain largely unexplored.
