Mindsight Glossary

Mindsight

Also: intuitive vision, eyeless sight, non-visual perception, extraretinal vision

The demonstrated human capacity to perceive colors, shapes, text, and images without using the physical eyes. Operates through alternative perceptual channels involving the pineal gland, cardiac coherence, brainwave entrainment (alpha/theta states), and dermo-optical skin sensitivity. Documented systematically since the 1920s by Jules Romains and studied in Soviet laboratories, US government programs, and independent neuroscience research.

Distinct from Dr. Daniel Siegel's use of the same term for interpersonal neurobiology.

Dermo-Optical Perception

Also: skin vision, tactile vision, paroptic sense

The ability to detect light wavelengths and colors through the skin. Documented by Jules Romains in the 1920s, who coined the term "extraretinal vision" after experimenting with hundreds of subjects. Rosa Kuleshova demonstrated the ability to read text through glass using only her fingertips in 1960s Soviet laboratory conditions. Yvette Duplessis found approximately one in six people exhibit this capacity under controlled conditions.

Cardiac Coherence

Also: heart coherence, heart rate variability coherence

A measurable physiological state where heartbeat rhythm becomes regular and harmonious at approximately 0.1 Hz (6 breaths per minute: 5 seconds inhale, 5 seconds exhale). In this state the parasympathetic nervous system is dominant, cortisol decreases, and DHEA increases. Researched extensively by the HeartMath Institute (Childre, Martin, Beech). Measurable with the EmWave device. Practitioners report direct correlation between cardiac coherence and mindsight performance.

Hemi-Sync

Also: hemispheric synchronization, binaural beats entrainment

A binaural audio technology developed by Robert Monroe and the Monroe Institute that synchronizes the two brain hemispheres through frequency-following response. Achieved by delivering slightly different audio frequencies to each ear; the brain generates a third "beat" frequency equal to the difference. This produces specific consciousness states , alpha (relaxed awareness), theta (deep meditation), delta (dreamless sleep) , without requiring years of meditation practice. Used in Mindsight Journey's guided meditation modules.

Biophoton

Also: ultra-weak photon emission, bioluminescence

Ultra-weak photon emissions produced by living cells. First observed by Alexander Gurwitsch in the 1920s; extensively researched by Fritz-Albert Popp (Nobel Prize nominee). DNA continuously emits and absorbs biophotons. Brain biophoton emissions increase in regions active during visual imagery even with eyes closed, suggesting the brain generates internal light during visualization. Popp's research indicates cells use biophoton signaling for intercellular communication.

Alpha Brainwave State

Also: alpha waves, alpha rhythm, alpha frequency band

Brain frequency range of 7.5–14 Hz, associated with relaxed awareness and the optimal neurological condition for intuitive perception. Children ages 3–6 naturally operate in this range (9–10 Hz). Adults typically transition into beta (14–21 Hz) as the dominant state after age eight. Adults can re-enter alpha through meditation, cardiac coherence breathing, or binaural audio. The adjacent theta state (3–7.5 Hz) corresponds to deep meditation and hypnagogic imagery. Researched by Jose Silva (Silva Method) in relation to extrasensory perception.

Piezoelectric Crystal

Also: calcite microcrystal

A crystal that converts mechanical vibration into electrical signal (and vice versa). The pineal gland contains calcite microcrystals with piezoelectric properties, discovered by Professor Sergio Felipe de Oliveira at the University of São Paulo in 1998. These crystals respond to light and electromagnetic vibration and may convert environmental electromagnetic signals into nerve impulses the brain can process, suggesting the pineal gland may function as an internal antenna for non-visual perception.

Theta Brainwave State

Also: theta waves, theta rhythm, theta frequency band

Brain frequency range of 3–7.5 Hz, associated with deep meditation, hypnagogic imagery, subconscious access, and vivid inner vision. The state naturally entered between waking and sleep. Many researchers , including Jose Silva and Makoto Shichida , consider the theta state the primary neurological window for advanced intuitive perception and remote viewing. Accessed through deep meditation, Hemi-Sync audio entrainment, or prolonged cardiac coherence breathing sessions.

Brainwave Entrainment

Also: neural entrainment, frequency-following response, photic driving

The process by which the brain synchronizes its electrical activity to an external rhythmic stimulus. When exposed to repeated auditory (binaural beats), visual (flickering light), or electromagnetic pulses at a specific frequency, the dominant brainwave pattern shifts toward that frequency. Used in mindsight training to guide practitioners from beta (analytical) into alpha (relaxed) and theta (deep intuitive) states without requiring years of meditation practice.

Binaural Beat

Also: binaural audio, binaural tones

An auditory processing artifact created when two slightly different frequencies are delivered simultaneously , one to each ear. The brain generates a third "beat" frequency equal to the difference (e.g., 200 Hz in the left ear and 210 Hz in the right ear produces a 10 Hz beat, which is alpha frequency). Discovered by Heinrich Wilhelm Dove in 1839. The Monroe Institute's Hemi-Sync technology uses binaural beats to induce specific consciousness states without requiring headphone isolation for phase separation.

Paroptic Sense

Also: extraretinal vision, eyeless sight, skin sight

Term coined by French author Jules Romains in his 1920 work "Eyeless Sight" to describe the ability to perceive visual information through channels other than the retina. Romains conducted controlled experiments with hundreds of subjects, demonstrating that some individuals could identify colors, shapes, and printed text using their fingertips, forehead, and other skin surfaces. The paroptic sense is considered the foundational mechanism underlying both dermo-optical perception and the broader mindsight phenomenon.

Extraretinal Vision

Also: non-retinal vision, vision without eyes, alternative vision

Any form of visual perception that does not rely on the eyes' retinal photoreceptors. Encompasses dermo-optical perception (skin-based light detection), pineal-gland-mediated perception, and other documented mechanisms. Soviet neuroscientist Natalia Bekhtereva used EEG and brain imaging to confirm that individuals with extraretinal vision activate the occipital visual cortex , the same region used in ordinary sight , through an alternative pathway. Distinct from blindsight, which involves residual retinal function.

Blindsight

Also: residual vision, unconscious vision

A neurological phenomenon where individuals with damage to the primary visual cortex (V1) retain the ability to respond to visual stimuli without conscious visual experience , they can reach for objects or detect motion while sincerely reporting that they cannot see. First systematically documented by Lawrence Weiskrantz in the 1970s. Demonstrates that visual information is processed through multiple parallel pathways beyond the primary visual cortex, providing neurological context for alternative perceptual channels explored in mindsight research.

Blindsight is a clinically documented neurological phenomenon distinct from trained mindsight, but it offers scientific evidence that visual processing does not require conscious retinal-cortical pathways.

Cardiac Field

Also: heart's electromagnetic field, heart field, cardiac electromagnetic field

The electromagnetic field generated by the heart, which is measurable up to several feet from the body. The heart generates the strongest bioelectromagnetic field in the human body , approximately 100 times stronger electrically and 60 times stronger magnetically than the brain's field, measured by the HeartMath Institute. This field encodes information about the body's emotional state and may function as a broadcast and reception antenna for intuitive information. Changes in cardiac field coherence correlate with measurable changes in intuitive performance.

Shichida Method

Also: right-brain education, Shichida child education

An educational methodology developed by Japanese educator Makoto Shichida based on the principle that the right brain hemisphere , responsible for intuitive, holistic, and visual processing , is highly active in young children but becomes suppressed as left-brain analytical training dominates conventional education. The method uses rapid image presentation, visualization exercises, and intuitive training to preserve and develop right-brain capacities. Shichida's afterimage training is a key step in developing the inner visualization screen used in mindsight.

Silva Method

Also: Silva Mind Control Method, Silva UltraMind

A self-improvement program developed by Jose Silva in the 1960s that trains practitioners to function in the alpha and theta brainwave frequencies during waking consciousness. Silva spent decades investigating the relationship between alpha brainwave states and extrasensory perception, concluding that the alpha state provides optimal neurological conditions for intuitive functioning. His research demonstrated that individuals trained to sustain alpha-state awareness showed marked improvements in non-ordinary perception. The Silva Method is one of the most widely studied methodologies for developing mindsight-adjacent abilities.

Remote Viewing

Also: RV, telesthesia, anomalous cognition

The documented ability to perceive information about distant or shielded locations, objects, or events through non-physical means. Studied by the US government's Stargate program at Stanford Research Institute for over 20 years. The American Institutes for Research concluded in 1995 that "by the standards applied to any other area of science, psychic functioning has been well established." Ingo Swann's 1973 remote viewing description of Jupiter's rings was confirmed by Voyager I six years later. Remote viewing is considered an advanced expression of the same perceptual channels developed through mindsight training.

Infovision

Also: Komissarov method, patented vision training

A patented methodology for developing non-visual perception developed by Russian chemical engineer Mark Komissarov, who collaborated with institutions for blind children to teach alternative vision. The Infovision program reports success with both sighted and blind students, with participants developing tactile color discrimination and intuitive shape recognition. Komissarov actively collaborated with blind schools in Russia and reported that students who developed Infovision also gained increased independence, confidence, and self-esteem beyond the perceptual skill itself.
