imagery. Instead, researchers
studying waking imagery in blind and sighted individuals have generally concluded that
congenitally blind individuals’ imagery has characteristics that are functionally equivalent in
many ways to the characteristics of visual imagery reported by sighted individuals. The
images of totally congenitally blind individuals, however, lack the uniquely visual character-
istics such as color and brightness and result in slight differences from the performance of
sighted individuals on several imagery tasks. Researchers therefore use the terms visual
image and visual content to mean an image or experience whose properties are similar to
those of an object or scene viewed visually (with one’s eyes). Terms such as spatial image,
analog image, and even visuospatial image have been used to describe imagery that preserves
spatial and metric properties without relying specifically on the visual system. When Be ́rtolo
et al. (2003) used the term visual image, they often blurred the distinction between the two
descriptive categories. They did so for three mistaken reasons.

research showing not only that blind people are capable of drawing two-dimensional figures
but also that their drawings are similar to the drawings of sighted individuals in the depiction
of depth, motion, perspective, vantage point, surfaces, contours, edges, and other character-
istics. Kennedy did not interpret his findings as evidence that blind people experience visual
imagery. Rather, he attributed the accuracy of drawings by blind people to the overlap in
information obtained through visual and tactile perceptual systems.

Blind people talk about “watching TV,” “keeping an
eye on things,” “seeing what you mean,” “taking a look at something,” and “visualizing a
scene,” although these visual terms do not imply a visual component. These colloquial
expressions are simply the most convenient phrases that blind people have for communi-
cating their experiences. It should be noted that blind people also use the term visual to
describe imagery experiences that do not fit neatly into any other category of sensory
experience (Kerr & Johnson, 1991). Blind people who know, for example, that a star appears
as a small spot in the night sky may include stars in an image of a nighttime scene. Although
the blind person’s conception of a star may derive only from descriptions, he or she under-
stands it as a visual phenomenon and labels it accordingly. Likewise, blind people describing
dream imagery favor words such as visualize to explain their awareness of the detail of the
dream environment without having to move around or touch particular aspects of the dream
setting.

According to the synaesthetic model (Brugger, 2000; Irwin,
2000) the visual content of an OBE stems from cross-modal
processing wherein non-visual (e.g., somatic) sensations are
dedifferentiated into visual hallucinations of one’s body
and/or environment. In support of this, Brugger (2000) notes
a case of a patient who had cortical blindness but reported vi-
sual perceptions that were dependent upon the presence of
non-visual cues (Goldenberg et al., 1995). The experience of vi-
sual content during an OBE may occur because of functional
connectivity between cortical structures responsible for inte-
grating multimodal information that is rooted in a pre-exist-
ing tendency for such hyperconnectivity and manifested in
weak synaesthetic experiences. In line with the aforemen-
tioned research linking the TPJ to the occurrence of OBEs, it
is noteworthy that the parietal region is involved in the inte-
gration of multisensory information and has been implicated
in various neuroimaging studies of synaesthesia

Along similar lines, non-visual sensory
stimuli may be associated with particular visual phenomeno-
logical features of an OBE. For instance, whereas somatic, tac-
tile and vestibular information may contribute to the visual
representation of one’s physical body (Blanke et al., 2004; Irwin,
2000), exogenous cues such as auditory stimuli may be utilized
in the representation of environmental objects and other per-
sons

Abstract. Two blind monkeys were studied with an observational profile that was
previously shown to distinguish the effects of hallucinogens from those of other classes of
drugs. Lysergic acid diethylamide and dimethyltryptamine could be distinguished from
saline, chlorpromazine, d-amphctamine sulfate, and bromo-lysergic acid diethylamide by the
increased frequency of spasms, stereotypy, bump, and tracking. The hallucinogens also
produced dramatic increases in exploration and related behaviors normally seen only in
response to real visual or auditory stimuli. These behaviors are discussed in terms of their
similarity to behaviors observed with sighted monkeys in light and dark environments.

Hallucinations induced by psychedelic drugs often cause synesthesia-like experiences (Luke & Terhune, 2013), in which a sen-
sorial stimulus in one modality will consistently and involuntarily produce a second concurrent experience in a different one (Ward,
2013). Acquired synesthesia (Proulx, 2010; Proulx & Stoerig, 2006) or that attributed to drug ingestion, convolve sensory experience
from multiple modalities and elicit phenomenon that are not experienced solely in the ‘mind’s eye’, but instead are projected onto a
person’s reality in real time

sensory substitution devices that could evoke the missing sensory modality (e.g., vision) through stimulation of an intact senses (e.g.,
audition).

After loss of a particular sensory channel, the deprived cortex can
be activated by inputs from other sensory modalities. It is not
known whether activation of the rewired cortex evokes subjective
experiences characteristic of that cortex or consistent with the
rerouted sensory information. In a previous study, blind subjects
were trained to perform visual tasks with a tongue display unit, a
sensory substitution device that translates visual displays into
electrotactile tongue stimulation. This cross-modal sensory stimu-
lation activated their visual cortices. We now extend this finding by
using transcranial magnetic stimulation to examine the perceptual
correlates of training-induced plastic responses. We find that blind
subjects proficient with the use of the tongue display unit report
somatopically organized tactile sensations that are referred to the
tongue when transcranial magnetic stimulation is applied over the
occipital cortex. No such sensations were evoked in trained, blind-
folded, seeing control subjects who performed the sensory sub-
stitution task equally well. These data show that the perceptual
correlate of activity in a given cortical area reflects the character-
istics of its novel sensory input source.

"there is a natural (physical) body and there is a spiritual body" So states St. Paul, in his first "Epistle to the Corinthians." Psychic research, too, has long ago established the belief that within every material being is a non-material "double" a cryptic entity coiniciding, with minute exactitude, with the physical mechanism in every centre and cell."
