Complements to subcortical discrimination, binocular rivalry, magnetic resonance

Life itself is a beautiful interaction between art and science. You cannot escape this reality no matter what you say or do!

It is appropriate to repeat this participation request, in the circumstances in which the findings of recent research of amplification in art and science.

I'm writing in:

 Subcortical discrimination; binocular rivalry; magnetic resonance

 It is necessary that the institute that develops such themes to hire some artists

of fine art to creating many variations of binocular rivalry images, similar to those proposed by me.

This invitation, for paricipation, I repeated it in an article on ResearrchGate.

Amygdala Responses to Fearful and Happy Facial Expressions under ...

I repeat from the article:

Abstract

The human amygdala plays a crucial role in processing affective information conveyed by sensory stimuli. Facial expressions of fear and anger, which both signal potential threat to an observer, result in significant increases in amygdala activity, even when the faces are unattended or presented briefly and masked. It has been suggested that afferent signals from the retina travel to the amygdala via separate cortical and subcortical pathways, with the subcortical pathway underlying unconscious processing. Here we exploited the phenomenon of binocular rivalry to induce complete suppression of affective face stimuli presented to one eye. Twelve participants viewed brief, rivalrous visual displays in which a fearful, happy, or neutral face was presented to one eye while a house was presented simultaneously to the other. We used functional magnetic resonance imaging to study activation in the amygdala and extrastriate visual areas for consciously perceived versus suppressed face and house stimuli. Activation within the fusiform and parahippocampal gyri increased significantly for perceived versus suppressed faces and houses, respectively. Amygdala activation increased bilaterally in response to fearful versus neutral faces, regardless of whether the face was perceived consciously or suppressed because of binocular rivalry. Amygdala activity also increased significantly for happy versus neutral faces, but only when the face was suppressed. This activation pattern suggests that the amygdala has a limited capacity to differentiate between specific facial expressions when it must rely on information received via a subcortical route. We suggest that this limited capacity reflects a tradeoff between specificity and speed of processing.

I have published Binocular Rivalry techniques but for reasons of reservation for artistic purity have been rejected.
