Dynamic sensitivity of area V4 neurons during saccade preparation.

19 Jul 2009 During the preparation of saccadic eye movements, visual attention is confined to the target of intended fixation and there is a corresponding diminution of visual sensitivity at nontarget locations. Neurons within the macaque visual cortex exhibit ...

Where has all the inhibition gone? Insights from electrophysiological measures into negative priming without probe distractors.

17 Jul 2009 Responses to probe targets that have been distractors in a prime display are slower than responses to unrepeated stimuli, a finding labeled negative priming (NP). However, without probe distractors the NP effect usually diminishes. The present study ...

FMRI adaptation during performance of learned arbitrary visuomotor conditional associations.

16 Jul 2009 In everyday life, people select motor responses according to arbitrary rules. For example, our movements while driving a car can be instructed by color cues that we see on traffic lights. These stimuli do not spatially relate to the actions that ...

fMRI activation during spike and wave discharges evoked by photic stimulation.

16 Jul 2009 Photoparoxysmal response (PPR) is an electroencephalographic (EEG) trait characterized by the occurrence of epileptiform discharges in response to visual stimulation. Studying this trait helps to learn about mechanisms of epileptogenicity. While ...

The natural statistics of audiovisual speech.

15 Jul 2009 Humans, like other animals, are exposed to a continuous stream of signals, which are dynamic, multimodal, extended, and time varying in nature. This complex input space must be transduced and sampled by our sensory systems and transmitted to the ...

Dyslexia: a new synergy between education and cognitive neuroscience.

15 Jul 2009 Reading is essential in modern societies, but many children have dyslexia, a difficulty in learning to read. Dyslexia often arises from impaired phonological awareness, the auditory analysis of spoken language that relates the sounds of language to ...

Working memory in children with epilepsy: an event-related potentials study.

14 Jul 2009 PURPOSE: The aim of this study was to find out whether children with idiopathic epilepsy did show different cortical activation patterns compared to non-epileptic children during performance of a working memory task. To this end event-related ...

The mental number line modulates visual cortical excitability.

14 Jul 2009 The mental number line has been shown to exert an influence on the visuo-spatial allocation of attention, with presentation of numbers from the low and high ends of the mental number line inducing covert shifts of spatial attention to the left and ...

Anticipating intentional actions: the effect of eye gaze direction on the judgment of head rotation.

14 Jul 2009 Using a representational momentum paradigm, this study investigated the hypothesis that judgments of how far another agent's head has rotated are influenced by the perceived gaze direction of the head. Participants observed a video-clip of a face ...

The part task of the part-spacing paradigm is not a pure measurement of part-based information of faces.

13 Jul 2009 BACKGROUND: Faces are arguably one of the most important object categories encountered by human observers, yet they present one of the most difficult challenges to both the human and artificial visual systems. A variety of experimental paradigms ...
