Bayesian reconstruction of natural images from human brain activity.

22 Sep 2009 Recent studies have used fMRI signals from early visual areas to reconstruct simple geometric patterns. Here, we demonstrate a new Bayesian decoder that uses fMRI signals from early and anterior visual areas to reconstruct complex natural images. ... Read more...

Resting cerebral blood flow: a potential biomarker of the effects of HIV in the brain.

30 Aug 2009 OBJECTIVE: HIV enters the brain soon after infection causing neuronal damage and microglial/astrocyte dysfunction leading to neuropsychological impairment. We examined the impact of HIV on resting cerebral blood flow (rCBF) within the lenticular ... Read more...

Modulation of the contrast response function by electrical microstimulation of the macaque frontal eye field.

24 Aug 2009 Spatial attention influences representations in visual cortical areas as well as perception. Some models predict a contrast gain, whereas others a response or activity gain when attention is directed to a contrast-varying stimulus. Recent evidence ... Read more...
