Alpha phase-amplitude tradeoffs predict visual perception
WebThey can be a form of phosphene. Some people report CEV under the influence of psychedelics; these are reportedly of a different nature than the "open-eye" hallucinations of the same compounds. Similar hallucinations that occur due to loss of vision are called visual release hallucinations . Levels of CEV perception [ edit] WebMain results - Conscious phosphene perception activated frequency-specific networks, each associated with a specific spatial scale of information processing. Integration increased within an alpha-band functional network, while changes in segregation occurred in the beta band. Significance - These results bring novel evidence for the functional ...
