Neural activity throughout the cortex is correlated with perceptual decisions

A new study from the Tank and Brody Labs published in Neuron finds that more complex tasks engage more widespread computations across the cortex. 
 
Neural activity throughout the cortex is correlated with perceptual decisions, but inactivation studies suggest that only a small number of areas are necessary for these behaviors. Virtual reality combined with optical recording and perturbation methods are used to show that the number of required cortical areas and their dynamics vary across related tasks with different cognitive computations.
