The Dynamical Regime of Sensory Cortex: Stable Dynamics around a Single Stimulus-Tuned Attractor Account for Patterns of Noise Variability
2018
Neuron
Highlights d A simple network model explains stimulus-tuning of cortical variability suppression d Inhibition stabilizes recurrently interacting neurons with supralinear I/O functions d Stimuli strengthen inhibitory stabilization around a stable state, quenching variability d Single-trial V1 data are compatible with this model and rules out competing proposals SUMMARY Correlated variability in cortical activity is ubiquitously quenched following stimulus onset, in a stimulus-dependent manner.
