THE USE OF PHANTOM CONTOURS TO ISOLATE MAGNOCELLULAR AND PARVOCELLULAR RESPONSES

International Journal of Neuroscience, 2006
In some "flickering" spot stimuli, two kinds of percepts can be seen at different frequencies: phantom contours and "surface characteristics." It has been proposed that their perception may be used to evaluate the magnocellular and parvocellular systems. This, however, is problematic.

Magnocellular and parvocellular contributions to backward masking dysfunction in schizophrenia

Schizophrenia Research, 2003
Patients with schizophrenia have repeatedly shown deficits in visual processing. These deficits have been well documented using visual backward masking (VBM). The VBM deficit in schizophrenia is thought to be due to aberrant interactions between magnocellular (M) and parvocellular (P) visual pathways.

The magnocellular and parvocellular paraventricular nucleus of rat: Intrinsic organization

Journal of Comparative Neurology, 1982
AbstractThe magnocellular and parvocellular regions of the rat hypothalamic paraventricular nucleus (PVN) were examined in several hundred brains. Converging qualitative and quantitative anatomical methods, including Golgi impregnations, Nissl stains, silver stains, and immunocytochemistry were used to study the intrinsic organization of the PVN with ...

Visual Attention to Color: Parvocellular Guidance of Attentional Resources?

Psychological Science, 2002
Although transient changes in luminance have been well documented to automatically attract attention to their location, experiments looking at abrupt changes in color have failed to find similar attentional capture. These results are consistent with current theories of the role of the magnocellular (M) and parvocellular (P) streams that postulate that

Magnocellular and parvocellular influences on reflexive attention

2007
There is currently disagreement in the visual attention literature regarding the stimulus features capable of triggering a reflexive shift of attention. One theory posits that features activating the magnocellular (M) visual stream, such as abruptly appearing objects with luminance contrast and low spatial frequencies, are responsible for activating ...
