Introduction: The concept of telepathy and extrasensory perception (ESP) has intrigued humanity for centuries, with scientific interest dating back to the late 19th century. In the latter half of the 20th century, advancements in technology transformed the study of these phenomena from anecdotal cases to controlled research. Charles Tart’s early 1960s electroencephalography (EEG) study marked a pivotal shift, revealing significant activity in the receiver coinciding with remote stimuli. Similarly, Duane and Behrendt observed EEG correlations in identical twins, suggesting a connection beyond the conventional sensory pathways. Grinberg-Zylberbaum’s experiments in Mexico during the late 80s and early 90s documented evidence of a connection between the brain of a person (the sender) who was shown light stimuli and the emergence of similar brain’s evoked potentials in the occipital lobe in another person (the receiver) who had not been exposed to any stimuli. Remarkably, both individuals were placed in separate Faraday cages during the experiments, suggesting a profound, unexplained form of communication between their brains. Despite controversy and criticism, subsequent studies sought to replicate these findings, exploring the nuances of EEG similarities between stimulated and non-stimulated subjects across various setups. More recent efforts by Patrizio Tressoldi and colleagues at Evanlab, employing auditory and visual stimuli, have underscored the potential role of the occipital and frontal brain regions in such interactions. These studies collectively suggest that the correlations observed between EEGs might be linked to intuition, potentially bridging conscious and unconscious processes. Research at the Institute of Noetic Sciences, for instance, has indicated statistically significant correlations between the electrogastrograms (EGGs) of closely related subjects in response to emotionally charged stimuli. This body of research points towards a complex interplay between emotional connection, sensory perception, and non-local communication, challenging traditional understandings of human connectivity and consciousness.

Ramsés D’León is Chief Researcher at “Unidad Parapsicológica de Investigación, Difusión y Enseñanza (UPIDE)”, Founding Member of the “Centro de Investigación de la Sintergia y la Consciencia (CISC)”, and Office Manager of the Parapsychological Association. My principal interests in the field are psychokinesis, physiological anticipation, and AI interactions, though I’m also engaged in reaching the field to students and researchers in other disciplines.

The Parapsychological Association is an international professional organization of scientists and scholars engaged in the study of psi (or ‘psychic’) experiences, such as telepathy, clairvoyance, psychokinesis, psychic healing, and precognition. The primary objective of the PA is to achieve a scientific understanding of these experiences.
