Visual recalibration of auditory spatial perception: two separate neural circuits for perceptual learning.

2 Sep 2009 A remarkable example of rapid perceptual learning is the visual recalibration of auditory spatial perception, which can result in either a bias (ventriloquism after-effect) or an improvement (multisensory enhancement) in auditory localization. Here, ...

Analogous intermediate shape coding in vision and touch.

2 Sep 2009 We recognize, understand, and interact with objects through both vision and touch. Conceivably, these two sensory systems encode object shape in similar ways, which could facilitate cross-modal communication. To test this idea, we studied single ...

"Real-time" obstacle avoidance in the absence of primary visual cortex.

31 Aug 2009 When we reach toward objects, we easily avoid potential obstacles located in the workspace. Previous studies suggest that obstacle avoidance relies on mechanisms in the dorsal visual stream in the posterior parietal cortex. One fundamental question ...

Mislocalization of flashed and stationary visual stimuli after adaptation of reactive and scanning saccades.

31 Aug 2009 When we look around and register the location of visual objects, our oculomotor system continuously prepares targets for saccadic eye movements. The preparation of saccade targets may be directly involved in the perception of object location because ...

Motion opponency and transparency in the human middle temporal area.

30 Aug 2009 Motion transparency is the perception of multiple, moving surfaces within the same retinal location (for example, a ripple on the surface of a drifting stream), and is an interesting challenge to motion models because multiple velocities must be ...

Effects of different viewing perspectives on somatosensory activations during observation of touch.

30 Aug 2009 Previous studies showed that neurons in the monkey premotor cortex became active when performing a particular action and also when observing the same action performed by others. These findings suggest a mirror system for action observation. ...

Spatiotemporal mapping of sex differences during attentional processing.

30 Aug 2009 Functional neuroimaging studies have increasingly aimed at approximating neural substrates of human cognitive sex differences elicited by visuospatial challenge. It has been suggested that females and males use different behaviorally relevant ...

Functional connectivity between the thalamus and visual cortex under eyes closed and eyes open conditions: a resting-state fMRI study.

30 Aug 2009 The thalamus and visual cortex are two key components associated with the alpha power of electroencephalography. However, their functional relationship remains to be elucidated. Here, we employ resting-state functional MRI to investigate the ...

Does a view of nature promote relief from acute pain?

30 Aug 2009 Inadequate control of acute pain is a well-recognized and serious problem. Distraction is one of the methods used in adjunct with medications to relieve pain. Nature-related sensory stimuli are frequently used for both distraction and relaxation. ...

Simple cell response properties imply receptive field structure: balanced Gabor and/or bandlimited field functions.

30 Aug 2009 The classical receptive fields of simple cells in mammalian primary visual cortex demonstrate three cardinal response properties: (1) they do not respond to stimuli that are spatially homogeneous; (2) they respond best to stimuli in a preferred ...
