The geometry of perisaccadic visual perception.
Our ability to explore our surroundings requires a combination of high-resolution vision and frequent rotations of the visual axis toward objects of interest. Such gaze shifts are themselves a source of powerful retinal stimulation, and so the visual system appears to have evolved mechanisms to maintain perceptual stability during movements of the eyes in space. The mechanisms underlying this p...
متن کاملPerisaccadic visual perception.
Primates use frequent, rapid eye movements to sample their visual environment. This is a fruitful strategy to make the best use of the highly sensitive foveal part of the retina, but it requires neural mechanisms to bind the rapidly changing visual input into a single, stable percept. Studies investigating these neural mechanisms have typically assumed that perisaccadic perception in nonhuman p...
متن کاملPerisaccadic perception of visual space in people with schizophrenia.
Corollary discharge signals are found in the nervous systems of many animals, where they serve a large variety of functions related to the integration of sensory and motor signals. In humans, an important corollary discharge signal is generated by oculomotor structures and communicated to sensory systems in concert with the execution of each saccade. This signal is thought to serve a number of ...
متن کاملAssessing users' visual perception based on the regular and irregular geometry of space organizer
Perception is a cognitive process depends on various factors of the environment. The user's mentality can affect his perception, understanding, and behavior in the environment. Organizing the environment is one of the important factors in the formation of spatial communication of elements that can be an important factor in understanding the person from his or her surroundings. In this research,...
متن کاملModeling perisaccadic time perception
There is an impressive scarcity of quantitative models of the clock patterns in the brain. We propose a mesoscopic approach, i.e. neither a description at single neuron level, nor at systemic level/too coarse granularity, of the time perception at the time of the saccade. This model uses functional pathway knowledge and is inspired by, and integrates, recent findings in both psychophysics and n...
