The page can be renamed to [[Closed-eye hallucination]] to avoid misinterpretation with ''internal auditory hallucination'' (another type of internal hallucination - http://hallucinations.enacademic.com/996 ). Closed-eye hallucination is a well known term (see https://en.wikipedia.org/wiki/Closed-eye_hallucination) while the term closed-eye visualization (CEV) is used by erowid.org (both by the staff and in trip reports), and in forums. What do you think {{ping|Josikins}}? --[[User:David Hedlund|David Hedlund]] ([[User talk:David Hedlund|talk]]) 21:43, 11 December 2017 (CET)

From personal experience, I've never encountered somebody who uses the term CEV to refer to anything but how their geometry is vastly more intense and detailed with eyes closed. That wikipedia article also primarily talks about geometry and not hallucinations. It's also possible and very common to have these with open eyes, particularly in dark rooms which is an extremely common setting for psychedelic experiences. I would prefer not to rename it because I think internal hallucinations is more specific and less ambiguous in terms of what it refers to.

Thank you for the suggestion though, I fully support adding it as alternative terminology within the article as you have already done.

: Ok. But what about ''internal auditory hallucination'' that I pointed out.? --[[User:David Hedlund|David Hedlund]] ([[User talk:David Hedlund|talk]]) 00:18, 13 December 2017 (CET)

sorry, what about it? I think the terminology should be kept consistent between different sensory categories of effects. So external vs internal auditory hallucinations should remain the same. I don't think people are going to misinterpret the two, especially when its listed in a visual subcategory.

Just double checked the auditory hallucinations, i suspect it should also be split into two components, internal vs external auditory hallucinations.

==Neurological Analysis==

===Internal hallucinations are induced by a lack of external stimuli due to hallucinogens impairing your ability to discriminate external stimuli===

“The dysbalance may reflect a shift away from external stimulus-driven toward internal-driven information processing and therefore may be a determining factor for the formation of visual hallucinations. In line with this view, several computational models postulate that an increase in the excitability of the visual network in the absence of visual input destabilizes spontaneous neuronal activity, which results in the formation of elementary visual hallucinations”<ref>Kometer, M., Schmidt, A., Jäncke, L., & Vollenweider, F. X. (2013). Activation of serotonin 2A receptors underlies the psilocybin-induced effects on α oscillations, N170 visual-evoked potentials, and visual hallucinations. Journal of Neuroscience, 33(25), 10544-10551. https://doi.org/10.1523/JNEUROSCI.3007-12.2013</ref>

p. 255 “Consequently, augmentation of sensory information occurs and there are multisensory aberrations marked by fluctuations in evoked potentials, resulting in events characterized as increased distractibility. Behaviorally, this translates into an impairment in discrimination based on external stimuli and a preoccupation with internal imagery and hallucinations.“<ref>Siegel, R. K. (1985). LSD hallucinations: from ergot to electric kool-aid. Journal of Psychoactive Drugs, 17(4), 247-256. https://doi.org/10.1080/02791072.1985.10524329</ref>

p. 2558 “The nonprimary visual areas strongly modulated by Ayahuasca (BA7, BA18, and BA19) are known to be activated during psychopathological hallucinations [Allen et al., 2008] as well as during normal dreaming, within rapid-eye-movement (REM) sleep [Braun et al., 1998; Wehrle et al., 2007].“<ref>de Araujo, D. B., Ribeiro, S., Cecchi, G. A., Carvalho, F. M., Sanchez, T. A., Pinto, J. P., ... & Santos, A. C. (2012). Seeing with the eyes shut: neural basis of enhanced imagery following ayahuasca ingestion. Human brain mapping, 33(11), 2550-2560. https://doi.org/10.1002/hbm.21381</ref>
