A mechanism of this sort, found in visual processes [23] (and also in tactile [24], auditory [25], and olfactory processing [26]) is called lateral inhibition, during which an excited neuron reduces the activity of its neighbors by disabling the spreading of action potentials to neighboring neurons in the lateral direction.
These results support a potential relationship between extensive visual experience with a stimulus domain and alterations in visual processes within the first 200 ms of perceptual identification.
Dysfunction in visual processes such as eye tracking, visual backward masking, motion perception, and contrast detection were observed in patients with schizophrenia and bipolar disorder.
In addition to our built-in visual processes, each of us brings to a work of art our acquired memories: we remember other works of art that we have seen.
However, several reports from other paradigms demonstrate that simple affective modulation, such as classically conditioned aversion, can impact ERP components as early as 120 160 ms [ 34] suggesting the possibility that fast, emotion-sensitive processes may run in parallel to visual processes, and can have an impact on visual ERP responses.
In a review of visual processes following picture presentation, this set of regions is typically identified over and above activations associated with word generation or overt responses (Indefrey and Levelt, 2004).
The current trial compared upregulation of brain areas involved in emotion processing (NFE) with an active control procedure that involved upregulation of brain areas involved in higher visual processes (NFS).
Supporting this conclusion, plasticity in those visual processes responsible for individuating between faces within a race, that is, the perceptual mechanisms underlying the other-race effect, produces concomitant changes in our subjects' measured implicit racial bias.
The data provides evidence for a behaviourally measurable imbalance in inhibitory and excitatory visual processes in migraine and is incompatible with a simple model of reduced cortical inhibitory function within the visual system.
Retinol (vitamin A alcohol) is considered the primary active form of the vitamin, although retinal, or vitamin A aldehyde, is the form involved in the visual process in the retina of the eye.
Again, as in Experiment 1, the visual processes engaged to encode and retain (particularly context) information presented in pictorial form are clearly affected even in subclinical forms of depression.
