Perceptual decision making is formalized as the accumulation of (noisy) sensory evidence until a decision threshold is crossed. Much understanding has been gained from studies of monkey neurophysiology and human neuroimaging as well as by computational modeling but there are still fascinating open questions about mechanisms of perceptual decision making. Perceptual decisions can be made […]

Reading the mind’s eye: Online detection of visuo-spatial working memory and visual imagery in the inferior temporal lobe
Posted on behalf of Jaime Martinez: The authors of the present work studied the extent to which visual brain regions participate in non-sensory cognitive processes of visual representation. To this end, they evaluated the role of ventral visual pathway areas in visual imagery and working memory by analyzing intracerebral EEG recordings from the left inferior […]
Variation in the human cannabinoid receptor CNR1 gene modulates gaze duration for happy faces
The authors of the current study (2) investigated the relationship of common genetic variations and gaze patterns. In particular, they tested whether variations in the cannabinoid receptor 1 (CNR1) gene would modulate gaze duration on (happy) faces. To this end, four single-nucleotide polymorphisms (SNPs) in the CNR1 gene were genotyped in 30 healthy subjects (13 […]
