Spike-Based Bayesian-Hebbian Learning of Temporal Sequences
Fig 6
Upkeep of stable sequential state switching during recall is permitted by the interplay of excitation and inhibition in a single neuron.
(A) Recorded Vm of a randomly chosen single cell whose period of increased tendency for being suprathreshold coincided with its brief engagement within an attractor. The red dotted line represents the membrane voltage threshold Vt for reference, and the shaded area represents a detected attractor state that is reproduced in B-D. (B) The same cell’s net NMDA current, which combined positive and negative afferent BCPNN weights. (C) The same cell’s net AMPA current, which combined positive and negative afferent BCPNN weights. (D) The same cell’s GABA current originating from local basket cell inhibition.
