Induction or modulation of synaesthesia through drug use.
Artificial synaesthesia or artificial paradises?
LSD reduces connectivity within brain networks, or the extent to which nerve cells or neurons within a network fire in synchrony.
LSD led to a more chaotic brain state not entirely dissimilar to what is seen in the prodromal phase of psychosis.
Increases in blood flow in the visual cortex at the back of the brain, which might explain the visual hallucinations and distortions so common in LSD intoxication. Decrease in alpha waves across the brain...the visual system is tethered more to the internal than to the external world.
LSD breaks the boundaries between well-established brain networks....networks start to blend with each other. The brain becomes more globally connected, operating in a more flexible way
Consistent with the extant literature,
LSD produced only weak spontaneous synaesthesia-like experiences relative to placebo.
LSD-induced synaesthesia-like experiences do not meet two established criteria for synaesthesia: inducer-specificity and stimulus-colour consistency. .
LSD did not substantially alter the tendency to experience colour concurrents in response to sounds and graphemes and that stimulus-colour experiences under the influence of LSD did not meet accepted criteria for synaesthesia.
Insight into why LSD is linked to a transformed sense of consciousness and an intense feeling of “oneness” with other human beings and the universe, but also why people on acid can experience a loss of personal identity or confusion.
