We studied the neural substrate of anticipation and learning of smooth pursuit eye movements in humans using fMRI. Both predictable and non-predictable eye movements, compared to baseline, activated a common network previously associated with oculomotor function. The temporal dynamics of activity in a subset of these areas suggested a strong correlation(More)
This study reports a new approach to studying the time-course of the perceptual processing of objects by combining for the first time the masked repetition priming technique with the recording of event-related potentials (ERPs). In a semantic categorization task ERPs were recorded to repeated and unrelated target pictures of common objects that were(More)
It has been established that repeated presentation of a transient target motion stimulus such as a constant-velocity ramp leads to the build up of steady state (SS), anticipatory smooth pursuit eye movements after two or three presentations. Each SS response is then composed of the anticipatory component of nonvisual origin, a visual component associated(More)
The most important factor allowing the generation of pursuit eye movements prior to target onset is confidence in the likelihood of imminent target appearance. We show how these anticipatory pursuit responses are essentially ballistic motor primitives and how the signal that drives them in normally defined by stored information concerning target speed,(More)
The aim of this study was to further elucidate the mechanisms of early and automatic object processing using a masked picture priming paradigm with both identity and exemplar repetition in functional MRI (fMRI). Masked repetition priming has been commonly used with words to isolate automatic, rapidly occurring mechanisms involved in visual word recognition;(More)
It is well established that pacemaker neurons in the brainstem provide automatic control of breathing for metabolic homeostasis and survival. During waking spontaneous breathing, cognitive and emotional demands can modulate the intrinsic brainstem respiratory rhythm. However the neural circuitry mediating this modulation is unknown. Studies of supra-pontine(More)
The VITEK 2 (bioMérieux, Marcy L'Etoile, France) and the Phoenix systems (BD Diagnostic Systems, Sparks, Md.) are automated instruments for rapid organism identification and susceptibility testing. We evaluated the workflow, the time to result, and the performance of identification and susceptibility testing of both instruments. A total of 307 fresh(More)
