EEG coherence in post-LSD visual hallucinations
Other Times I Can Barely See: The Effects of Hallucinogens on Vision and Attention
TLDR
Two double-blind placebo-controlled experiments on the effects of the serotonergic drugs 3,4-methylenedioxyamphetamine (MDA) and 3, 4- methylenedioxymethamphetamine (MDMA) on attention to emotional stimuli and preliminary evidence that MDA and MDMA may modify processing of threat-related stimuli is found.
A Review of Hallucinogen Persisting Perception Disorder (HPPD) and an Exploratory Study of Subjects Claiming Symptoms of HPPD.
TLDR
Results of the survey suggest that HPPD is in most cases due to a subtle over-activation of predominantly neural visual pathways that worsens anxiety after ingestion of arousal-altering drugs, including non-hallucinogenic substances.
Hallucinogen Persisting Perception Disorder (HPPD) and Flashback-are they Identical?
TLDR
With its potentially neuroprotective and mood-stabilising properties, lamotrigine may offer a promising new therapeutic approach for the treatment of Hallucinogen persisting perception disorder.
On Perception and Consciousness in HPPD: A Systematic Review
TLDR
Unlike the acute stages of psychedelic drug intoxication, which may be accompanied by altered states of consciousness, HPPD is rather characterized by changes in the content of consciousness and an attentional shift from exogenous to endogenous phenomena.
Flashback phenomena after administration of LSD and psilocybin in controlled studies with healthy participants.
TLDR
Reoccurring drug-like experiences after the administration of LSD and psilocybin are a common phenomenon occurring in up to 9.2% of healthy subjects and it is suggested that flashback phenomena are not a clinically relevant problem in controlled studies with healthy participants.
EEG Gamma Coherence and Other Correlates of Subjective Reports During Ayahuasca Experiences
TLDR
Findings include increased modal EEG alpha frequency and global power decreases across the cortex in most frequency bands, which concur with the EEG of psychedelics literature and find increases in global gamma coherence during peak psychedelic experiences.

Brain electrical activity mapping (BEAM) in schizophrenic patients.
TLDR
A new topographic approach, brain electrical activity mapping, summarizes EEG and evoked potential data as color maps, finding that both schizophrenic groups had more slow activity in frontal regions, and more fast activity in postcentral regions.
Effects of a hallucinogenic agent in totally blind subjects.
TLDR
The role of a functioning retina in the induction of LSD-induced visual changes is clarified by studying subjects with total blindness (no light perception) and, insofar as possible, normal central nervous system.
Age‐related differences in brain electrical activity of healthy subjects
A combined neurophysiological (electroencephalographic [EEG] and sensory evoked potential) and neuropsychological investigation was performed on 63 healthy men ranging in age from 30 to 80 years.
Auditory P300 abnormalities and left posterior superior temporal gyrus volume reduction in schizophrenia.
TLDR
Initial data appear most compatible with a model that postulates a major role for bilateral STG sources in P300 generation: the strongly asymmetric STG volume reduction found in many schizophrenic subjects produces asymmetric P300 amplitudes at lateral electrode sites, where the influence of the abnormal region is most easily detected.

TLDR
Sensitivity to LSD as determined by flashbacks appears to divide the study sample into three discrete subgroups, and there may be a genetic basis to LSD sensitivity.
Dyslexia: Regional differences in brain electrical activity by topographic mapping
TLDR
Electroencephalographic and evoked potential data were recorded during behavioral testing from 8 dyslexic and 10 normal boys aged 9 to 11 years, suggesting relative cortical inactivity in that group.
