Neural circuit mechanisms for multi-tasking

Neural activity during performance of a cognitive or motor task is often described as lying on a low-dimensional manifold in the space of all possible activity patterns. When multiple tasks are performed, an individual brain region’s activity may generate multiple such manifolds. Several models have been introduced to...

Shaping Slow Manifolds in Equivariant Recurrent Neural Networks.

Recordings of increasingly large neural populations have revealed that the firing of individual neurons is highly coordinated. When viewed in the space of all possible patterns, the collective activity forms nonlinear structures called neural manifolds. Because such structures are observed even at rest or during sleep,...

Irregular and bursty neuronal firing extend spike-timing dependent plasticity window to behavioral timescales

It is found that irregular spike-pair stimulation diminished LTD occurrence and widened the LTP temporal window compared to regular patterns at low firing rate, and increasing the firing rate abolished LTD to the profit of LTP.
