Bridging the gap: global disparity processing in the human visual cortex.

The human stereoscopic system is remarkable in its ability to utilize widely separated features as references to support fine depth discrimination. In a search for possible neural substrates of this ability, we recorded high-density EEG and used a distributed inverse technique to estimate population-level disparity responses in five regions of interest (ROIs): V1, V3A, hMT+, V4, and lateral occ...

The third dimension in the primary visual cortex.

Anatomical superposition of the cortical projections from the overlapping visual fields of the two eyes does not make it obvious how the disposition of objects in the third dimension is encoded. Hubel and Wiesel's demonstration that units in the primary visual cortex of the mammal respond preferentially to elongated contours of specific orientation encouraged the inquiry into whether binocular ...

An fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli

  ABSTRACT  Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF).  Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd.  Results: Average percentage BOLD signa...

Bridging the ‘Two Cultures’ of Research and Service: Can Complexity Theory Help?; Comment on “Experience of Health Leadership in Partnering With University-Based Researchers in Canada – A Call to ‘Re-imagine’ Research”

This commentary addresses Bowen et al’s empirical study of perspectives of Canadian healthcare staff towards research and their call for multi-faceted action to improve misalignments in the system. This commentary argues that tensions and misalignments between research and service are inherent and can never be eradicated. Building on previous work by Lanham et al, I pro...

Stereoscopic processing of absolute and relative disparity in human visual cortex.

Stereoscopic vision relies mainly on relative depth differences between objects rather than on their absolute distance in depth from where the eyes fixate. However, relative disparities are computed from absolute disparities, and it is not known where these two stages are represented in the human brain. Using functional MRI (fMRI), we assessed absolute and relative disparity selectivity with st...
