Typicality sharpens category representations in object-selective cortex
The purpose of categorization is to identify generalizable classes of objects whose members can be treated equivalently. Within a category, however, some exemplars are more representative of that concept than others. Despite long-standing behavioral effects, little is known about how typicality influences the neural representation of real-world objects from the same category. Using fMRI, we sho...
متن کاملThe distribution of category and location information across object-selective regions in human visual cortex.
Since Ungerleider and Mishkin [Underleider LG, Mishkin M (1982) Two cortical visual systems. Analysis of Visual Behavior, eds Ingle MA, Goodale MI, Masfield RJW (MIT Press, Cambridge, MA), pp 549-586] proposed separate visual pathways for processing object shape and location, steady progress has been made in characterizing the organization of the two kinds of information in extrastriate visual ...
متن کاملOrthogonal coding of object location.
It has been argued whether internal representations are encoded using a universal ('the neural code') or multiple codes. Here, we review a series of experiments that demonstrate that tactile encoding of object location via whisking employs an orthogonal, triple-code scheme. Rats, and other rodents, actively move the whiskers back and forth to localize and identify objects. Neural recordings fro...
متن کاملAltering object representations through category learning.
Previous research has shown that objects that are grouped together in the same category become more similar to each other and that objects that are grouped in different categories become increasingly dissimilar, as measured by similarity ratings and psychophysical discriminations. These findings are consistent with two theories of the influence of concept learning on similarity. By a Strategic ...
متن کاملEffects of forced exercise on object location memory and anxiety behaviour in morphine dependent ovariectomized rats
Introduction: Previous findings from our laboratory indicated that exercise alleviates the deficits in cognitive and anxiety disorders in healthy female rats. But the effect of exercise on cognitive and anxiety disorders induced by chronic morphine in experimental monopose of rats (ovariectomized) not known. Aim of this study was to investigate the effects of mild and modorate forced exercise o...
