Instant performance recovery is possible following general anesthesia-induced unconsciousness using antagonist, and the brain dynamics return abruptly to the awake state without intermediate recovery states.
Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.
Changes to sensory predictions are encoded by beta oscillations, surprise due to prediction violations by gamma oscillations, and alpha oscillations may have a role in controlling the precision of predictions.
Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.
The secondary motor cortex causally contributes to flexible action selection during stimulus categorization with the representations of upcoming choice and sensory history regulated by the demand to remap stimulus–action association.
