Task-specific shaping of feature-based attention in area MT
Visual perception depends on the effective prioritization of visual information in order to concur with the current behavioral context. Depending on the context’s requirements, it is important to facilitate the processing of a certain feature (e.g. motion) in some situations, while in others another feature (e.g. color) is more crucial. We here address the question whether and how the specific ...
متن کاملProcessing of kinetically defined boundaries in the cortical motion area MT of the macaque monkey.
1. Electrophysiological recordings of 68 cells in the middle temporal area MT were made in paralyzed and anesthetized macaque monkeys. 2. Testing with our kinetic boundary stimuli always occurred under optimized conditions. To this end, the preferred direction, speed, stimulus position, and stimulus size of each cell were determined by quantitative tests. 3. The orientation selectivity to stati...
متن کاملDirection-specific adaptation in area MT of the owl monkey.
Single neurons were recorded in owl monkey middle temporal visual cortex (MT). Directional neurons showed direction-selective adaptation to pattern motion: responses to motion in the preferred direction were reduced by adaptation to motion in the preferred direction and enhanced by adaptation in the opposite direction. Non-directional neurons did not show significant adaptation.
متن کاملPsychophysical evidence for spatiotopic processing in area MT in a short-term memory for motion task.
The middle temporal (MT) area has long been established as a cortical area involved in the encoding of motion information and has been thought to do so in retinotopic coordinates. It was previously shown that memory for motion has a spatial component by demonstrating that subjects do significantly worse on a match-to-sample task when the stimuli to be compared were spatially separated. The dist...
متن کاملAttention to Surfaces Modulates Motion Processing in Extrastriate Area MT
In the visual system, early atomized representations are grouped into higher-level entities through processes of perceptual organization. Here we present neurophysiological evidence that a representation of a simple object, a surface defined by color and motion, can be the unit of attentional selection at an early stage of visual processing. Monkeys were cued by the color of a fixation spot to ...
