Science of Sleep: How is Sleep Regulated? sleep.hms.harvard.edu 3 facts
claimWhen neurons in the arousal areas of the brain are active, the cerebral cortex remains activated, which keeps humans awake.
claimSeveral areas in the brainstem and hypothalamus promote wakefulness by sending arousal signals, in the form of neurotransmitters, to the cerebral cortex.
claimOrexin (also known as hypocretin) is a neurotransmitter that directly stimulates arousal centers and the cerebral cortex.

claimLarge waves of gamma activity in the cerebral cortex are hypothesized to be an indication of coordinated local-global activity during conscious perception.
referenceThe paper 'A Switch and Wave of Neuronal Activity in the Cerebral Cortex During the First Second of Conscious Perception' (2019) by Herman et al. reports that consciously perceived stimuli elicit large-scale network switching followed by waves of gamma activity.

Effects of psychedelics on neurogenesis and broader neuroplasticity link.springer.com Dec 19, 2024 2 facts
claimPsychedelics are believed to primarily activate 5-HT2A serotonin receptors, which are G protein-coupled receptors abundant in the cerebral cortex responsible for characteristic hallucinogenic effects.
claimDelta-9-tetrahydrocannabinol (THC) has different apoptotic effects on the cerebral cortex of neonatal rats compared to adult rats.
4.5 Consciousness – Cognitive Psychology nmoer.pressbooks.pub 2 facts
claimVisual awareness depends on a reciprocal exchange of information across multiple brain areas, particularly within the cerebral cortex.
referenceThe Global Neuronal Workspace Theory of Consciousness, proposed by Dehaene and Changeux in 2011, postulates that the sharing of information among the prefrontal, inferior parietal, and occipital regions of the cerebral cortex is essential for generating awareness.
