Are Brain–Computer Interfaces Feasible With Integrated Photonic Chips?

Abstract: The present paper examines the viability of a radically novel idea for brain–computer interface (BCI), which could lead to novel technological, experimental, and clinical applications. BCIs are computer-based systems that enable either one-way or two-way communication between a living brain and an external machine. BCIs read-out brain signals and transduce them into task commands, which are performed by a machine. In closed loop, the machine can stimulate the brain with appropriate signals. In recent years, it… Show more

“…The anesthetic-induced collapse of the attractor certainly fits with an anesthetic-induced collapse of information integration that occurs at loss of consciousness ( Oizumi et al, 2014 ; Sarasso et al, 2015 ; Tononi et al, 2016 ; Eagleman and MacIver, 2018 , 2021 ; Eagleman et al, 2018a , b , 2019 ; Ward and Guevara, 2022 ). A more sophisticated approach would measure both electric and magnetic fields, together with photonic energies ( Salari et al, 2021 ), and combine these into multi-dimensional attractors. Even better would be approaches which allow us to record EMFs from deeper regions of the brain, like the thalamus, midbrain and brainstem, together with cortical level signals.…”

“…Neural implants have multiple applications in medicine, especially related to neurostimulation in motor and sensory disorders, but also epilepsy, and they are in early experimentation stage in depressive and obsessive-compulsive disorders (Costa e Silva & Steffen, 2017). This is a rapidly progressing research area in which biochips and implants are built in new and better materials that produce no tissue rejection, incorporating nanotechnologies to diminish the size and with more powerful software to control and interact with the neural system (Dabbour et al, 2021;Salari et al, 2022;Wan et al, 2021) while, again, there is no international regulation of its use (McGee & Maguire, 2007). The most important concern regarding the use of neuroimplants -not in the near future, for now -is represented by the possibility of controlling an individual's mental functions via wireless waves interacting with the electric activity of the brain.…”

“…Such correlations suggest that we may use UPEs as a correlative signal to monitor different internal states across the stages of ADRD pathology and to expand the clinical criteria, particularly in the preclinical and mild cognitive impairment (MCI) stages where memory loss and other problems are not always evident. Discrimination between the interferometric patterns of normal, and preclinical stages will be non-trivial but tractable via machine learning, based on observation of highly synchronized brain activities with strong UPE correlations for specific cognitive tasks (3). With an analysis of signals over thousands of training trials, it will be possible to obtain an average pattern for feature extraction, enabling pattern recognition directly during preclinical and premarket approval testing.…”

“…Diagnosing AD typically involves a combination of cognitive and memory tests, brain imaging studies, and other assessments performed by a clinician. Based on the observation that the brain spontaneously emits photons, so called ultraweak photon emissions (UPE) (1; 2), we suggest that a brain-computer interface with an integrated photonic chip (BCIPC)(3) may be an efficient real-time method for monitoring early symptoms of AD and related dementias (ADRD). The envisaged technology would support clinicians by providing complementary data to efficiently screen and diagnose AD.…”
