Phosphene Perception Relates to Visual Cortex Glutamate Levels and Covaries with Atypical Visuospatial Awareness.
Phosphenes are illusory visual percepts produced by the application of transcranial magnetic stimulation to occipital cortex. Phosphene thresholds, the minimum stimulation intensity required to reliably produce phosphenes, are widely used as an index of cortical excitability. However, the neural basis of phosphene thresholds and their relationship to individual differences in visual cognition a...
متن کاملAn fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli
ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...
متن کاملRetina or Visual Cortex? The Site of Phosphene Induction by Transcranial Alternating Current Stimulation
Since the fi rst descriptions of oscillatory synchrony in the cortex, a plethora of studies have provided empirical evidence for correlations between cortical oscillations and perception, attention, and other cognitive functions (Tallon-Baudry, 2009). However, it has remained diffi cult to obtain causal evidence for a role of oscillatory synchrony in cortical processing. Recent developments in ...

متن کاملPhosphene evaluation in a visual prosthesis with artificial neural networks
The electrical stimulation of the optic nerve is investigated, as an approach to the development of a microsystems-based visual prosthesis. Non-linear prediction models, i.e. artificial neural networks, for phosphene localisation are used and show promising results. The prediction error is reduced up to 20% in comparison with linear statistical models and the error standard deviation is restrai...
