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.
Behavioral, pharmacological, optogenetic, electrophysiological and computational analyses suggest that the anterior dorsal striatum is a causal node in the network responsible for evidence accumulation.
The strength of frequency-tagged neural activity during perceptual filling anti-correlates with the contents of consciousness, yet positively correlates with a neural measure of attention, dissociating these often confounded brain processes.
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.
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.
