Roberto.. , who's latest paper just got accepted for publication in Journal of Neuroscience.. Optimal Encoding of Interval Timing in Expert Percussionists.. Marco Cicchini.. , Luca Cecchetti, Marco Giusti and.. We measured temporal reproduction in human subjects with various levels of musical expertise: expert drummers, string musicians, and non-musicians.. While duration reproduction of the non-percussionists showed a characteristic central tendency or regression to the mean, drummers responded veridically.. Furthermore, when the stimuli were auditory tones rather  ...   Bayesian model that seeks to minimize reproduction errors by incorporating a central tendency prior, a probability density function centered at the mean duration of the sample.. We measured separately temporal precision thresholds with a bisection task; thresholds were twice as low in drummers as in the other two groups.. These estimates of temporal precision, together with an adaptable Bayesian prior, predict well the reproduction results and the central tendency strategy under all conditions and for all subject groups.. These results highlight the efficiency and flexibility of sensorimotor mechanisms estimating temporal duration..

Brief periods of monocular deprivation disrupt ocular balance in human adult visual cortex.. Neuroplasticity is a fundamental property of the developing mammalian visual system, with residual potential in adult human cortex.. A short period of abnormal visual experience (such as occlusion of one eye) before closure of the critical period has dramatic and permanent neural consequences, reshaping visual cortical organization in favour of the non-deprived eye.. We used binocular rivalry — a sensitive probe  ...   plasticity, with important perceptual consequences.. We report that 150 minutes of monocular deprivation strongly affects the dynamics of binocular rivalry, unexpectedly causing the deprived eye to prevail in conscious perception twice as much as the non-deprived eye, with significant effects for up to 90 minutes.. Apparent contrast of stimuli presented to the deprived eye was also increased, suggesting that the deprivation acts by up-regulation of cortical gain-control mechanisms of the deprived eye.. The results suggest that adult visual cortex retains a good deal of plasticity that could be important..

  • Title: Eckart in CB 2011
    Descriptive info: Eckart in CB 2011.. , who's latest paper just got accepted for publication in current biology.. Spatiotopic Visual Maps Revealed by Saccadic Adaptation in Humans.. Saccadic adaptation is a powerful experimental paradigm to probe the mechanisms of eye movement control and spatial vision, in which saccadic amplitudes change in response to false visual feedback.. The adaptation occurs primarily in the motor system, but there is also evidence for visual adaptation, depending on the size and the permanence of the postsaccadic error.. Here we confirm that adaptation has a strong visual component and show that  ...   task designed to maximize visual adaptation and to dissociate the visual and motor corrections.. When the memorized saccadic target was in the same position (in external space) as that used in the adaptation training, saccade targeting was strongly influenced by adaptation (even if not matched in retinal or cranial position), but when in the same retinal or cranial but different external spatial position, targeting was unaffected by adaptation, demonstrating unequivocal spatiotopic selectivity.. These results point to the existence of a spatiotopic neural representation for eye movement control that adapts in response to saccade error signals..
