  1. Zoe Kourtzi & Mark Augath, Integration of Local Features Into Global Shapes: Monkey and Human fMRI Studies.
    was to test the role of both early and higher visual areas in the integration of local features into global shapes. To this end, we conducted functional magnetic resonance imaging (fMRI) studies. Although fMRI lacks the high spatial resolution of intracortical recordings, it allows simultaneous collection of responses to the same stimulus set from multiple visual areas that is not possible with standard recording techniques. We performed these studies in monkeys, where much is known about the properties of neurons in (...)

    Learning is known to facilitate performance in a range of perceptual tasks. Behavioral improvement after training is typically shown after practice with highly similar stimuli that are difficult to discriminate (i.e. hard training), or after exposure to dissimilar stimuli that are highly discriminable (i.e. easy training). However, little is known about the processes that mediate learning after training with difficult compared to easy stimuli. Here we investigate the time course of learning when observers were asked to discriminate similar global form (...)

    The relationship between brain activity and conscious visual experience is central to our understanding of the neural mechanisms underlying perception. Binocular rivalry, where monocular stimuli compete for perceptual dominance, has been previously used to dissociate the constant stimulus from the varying percept. We report here fMRI results from humans experiencing binocular rivalry under a dichoptic stimulation paradigm that consisted of two drifting random dot patterns with different motion coherence. Each pattern had also a different color, which both enhanced rivalry and (...)
