I'm wondering if anyone has explored parallels between the concept of gain fields in the brain and coupled oscillators. I am totally blind with severely impaired spatial attention, and I hypothesize that galvanic vestibular stimulation, paired with eye tracking, could improve the resolution of spatial attention and increase sensory integration, including being able to use affordances (simulated reaching and walking) to utilize very degraded light perception. Coupling between receptive fields of eye, hand, and limb neurons in the parietal cortex create a phenomenal experience of using imaginal rotation, alterations in muscle tension and stretch to simulate circles and horizontal and vertical lines, at any angle relative to the body. . This in turn allows for the infrastructure to use postural and proprioceptive cues to develop a three-dimensional model of space, which can then be used to organize incoming sensory data into planes, with a clear distinction between "in front of" and "behind," leading to increasingly accurate top-down predictions about the meaning of this data. This sort of organization is necessary if auditory processing is otherwise impaired. By using GVs and eye tracking to increase the salience of the vestibular-oculo reflex and other primative reflexes that involve connection between the eyes and body, this three dimensional modeling of space can enter conscious awareness and therefore become useful to a blind person or a person struggling with sensory integration.

I've had this theory for years, and have not been able to do anything with it because I'm not a researcher, and cannot myself be a traditional research subject because of the vulnerability inherent in doing so. But I can be a thought partner for someone who would like to co-author a theoretical paper on this topic, which would lay the foundation for future research. To my knowledge these are completely novel ideas in that no one has yet applied GVS to sensory integration in the blind population.
