Experimental technique for recording neuronal activity based on the principle that intracellular calcium levels rise when neurons fire action potentials, which can be detected using fluorescent molecules that bind calcium.
Synchronous activity mediated by chemical synapses involving most neurons within a local network, manifesting either as brief (< 3 s) bursts involving small clusters of neighboring cells or as waves that propagate across a larger cortical region.
First described in vitro using calcium imaging, ENOs are synchronous network events occurring in the hippocampus and neocortex during the first postnatal week and driven by glutamatergic neurotransmission.
Essentially the same as ENOs but specifically involving GABAergic interneurons.

Large channels that connect the cytoplasm of two adjacent cells via heterameric connexin channels in the plasma membrane, which allows the rapid exchange of small molecules or ions, such as calcium. They make up electrical synapses.
Spontaneous network-mediated synaptic events driven by GABAergic neurotransmission observed in the developing brain of various species; first described in hippocampus.
Predominant pattern of CNA at P0-P6 in mouse neocortex in which largely non-overlapping clusters or patches of neurons fire synchronously, with the size of each patch corresponding to individual cortical columns (or barrels in vibrissal S1).
