How we perceive our own retina

چکیده

Ever since the days of René Descartes, in the seventeenth century, the search for the relationship between subjective perception and neural activity has been an ongoing challenge. In neuroscience, an approach to the problem via the visual system has produced a paradigm using perceptual suppression, changing with time. Cortical areas in which the neural activity was modulated in temporal correlation with this percept could be traced. Although these areas may lead directly to perception, such temporal correlation of neural activity does not suffice as ultimate proof that they actually do so. In this article, I will use a different method to show that, for the perception of our own retina, any brain area leading directly to this perception also needs to represent the retina without distortion. Furthermore, I will demonstrate that the phenomenon of size constancy must be realized in this area.

Filling in the Details: Perceiving from Low Fidelity Visual Input

Humans perceive their surroundings in great detail even though most of our visual field is reduced to low-fidelity color-deprived (e.g., dichromatic) input by the retina. In contrast, most deep learning architectures deploy computational resources homogeneously to every part of the visual input. Is such a prodigal deployment of resources necessary? In this paper, we present a framework for inve...

Comparison of effects of eye movements and stimulus movements on striate cortex neurons of the monkey.

AN IMAGE MOVES with respect to the retina both when our eves move a nd when the object moves, but in one case we perceive a stationary object, in the other case a moving object. How can we tell the difference? One approach to this question was proposed by Helmholtz (10) over a century ago. He suggested that when efferent impulses go to the eye muscles, other impulses go simultaneously to areas ...

Seeing what you want to see: priors for one's own actions represent exaggerated expectations of success

People perceive the consequences of their own actions differently to how they perceive other sensory events. A large body of psychology research has shown that people also consistently overrate their own performance relative to others, yet little is known about how these "illusions of superiority" are normally maintained. Here we examined the visual perception of the sensory consequences of sel...

Active vision in parietal and extrastriate cortex.

Vision is an active process. We do not see the world directly; rather, we construct a representation of it from sensory inputs in combination with internal, nonvisual signals. In the case of spatial perception, our representation of the visual scene must take into account our own movements. This allows us to perceive the world as stationary despite the constant eye movements that produce new im...

Being Barbie: The Size of One’s Own Body Determines the Perceived Size of the World

A classical question in philosophy and psychology is if the sense of one's body influences how one visually perceives the world. Several theoreticians have suggested that our own body serves as a fundamental reference in visual perception of sizes and distances, although compelling experimental evidence for this hypothesis is lacking. In contrast, modern textbooks typically explain the percepti...
