Electrical synapses are modified by various forms of activity, including paired activity in coupled neurons and tetanization of the input to coupled neurons.
We show that plasticity of electrical synapses that results from paired spiking activity in coupled neurons depends on calcium influx and calcium‐initiated signalling pathways.
Plasticity that results from tetanization of input fibres...
Changes in synaptic strength resulting from neuronal activity have been described in great detail for chemical synapses, but the relationship between natural forms of activity and the strength of electrical synapses had previously not been investigated. The thalamic reticular nucleus (TRN), a brain area rich in gap junctional (electrical) synapses, regulates cortical attention, initiates sleep spindles,...
