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.
LSD induces a pattern of changed global brain connectivity characterized by hypo-connectivity in associative areas and hyper-connectivity across sensory and somatomotor areas that is dependent on the serotonin 2A receptor.
Behavioral, pharmacological, optogenetic, electrophysiological and computational analyses suggest that the anterior dorsal striatum is a causal node in the network responsible for evidence accumulation.
Despite the widely held belief among researchers in consciousness that healthy observers can show unconscious perception, a study using a novel method to control for response biases finds no evidence for this phenomenon.
Intracranial recordings of human brain activity during awakening from general anesthesia exhibit a brief brain state not seen during loss of consciousness, in which stimuli elicit large electrophysiological responses that resemble those seen in sleep.
