Protocol for testing global neuronal workspace and integrated ... journals.plos.org 3 facts
procedureIn the mouse behavioral task, researchers train one group of mice to identify visual stimuli as targets and a balanced group to identify auditory stimuli as targets, with irrelevant stimuli presented alongside targets. Stimuli are presented for 0.5 or 1.5 seconds, preceded by a random pre-stimulus period of 1.5 to 4 seconds (mean 2 seconds) during which the mouse must withhold licking to prevent trial restart.
procedureIn the mouse task, targets are either a vertically-oriented grating or a 6 kHz pure tone, while non-targets are a horizontal grating or an 11 kHz pure tone. Visual stimuli are presented in grayscale at 100% luminance contrast with a spatial frequency of 0.04 cycles/degree and a size of 50 degrees.
procedureTo enable cross-species comparisons, the study protocol involves non-human primates (NHPs) and mice viewing or listening to supra-threshold visual or auditory stimuli for variable durations in a go-nogo task that controls for report confounds, while recording neuronal responses from visual, auditory, posterior parietal, and/or prefrontal cortical areas using Neuropixels electrodes.

procedureTo test theories of consciousness, the researchers manipulated attributes of conscious content by presenting suprathreshold visual stimuli across four categories (faces, objects, letters, and false fonts), with each category containing 20 unique identities shown in three orientations (front, left, and right) and for three durations (0.5, 1.0, and 1.5 seconds).

claimBlindsight is a neurological condition where individuals retain the ability to analyze and respond to visual stimuli without having conscious experiences of those stimuli. This was discussed by Lamme (2001).

accountIn a case series study, researchers examined four individuals who reported lucid sleep episodes in a controlled laboratory setting using a novel induction method that combines pre-sleep meditation and visual stimulation.

procedureThe experimental design for macaques involves three conditions: a target visual stimulus requiring a response, a non-target face not requiring a response, and an irrelevant visual stimulus, which allows researchers to distinguish between neural activity related to perception versus action.

referenceDocumented examples of unconscious processing include visual stimuli (Milner and Goodale, 2006), pain (Melzack and Wall, 1982), threatening events (LeDoux, 1996), blindsight (Weiskrantz, 1990), covert facial recognition (Young and Burton, 1999), and implicit memory (Schacter, 1987).
