Brain activation patterns during measurement of sub- and supra-second intervals.
The possibility that different neural systems are used to measure temporal durations at the sub-second and several second ranges has been supported by pharmacological manipulation, psychophysics, and neural network modelling. Here, we add to this literature by using fMRI to isolate differences between the brain networks which measure 0.6 and 3s in a temporal discrimination task with visual disc...
متن کاملEditorial: Sub- and Supra-Second Timing: Brain, Learning and Development
Time perception in the range of milliseconds to a few seconds is essential for many important sensory and perceptual tasks including speech perception, motion perception, motor coordination, and cross-modal interaction. For the brain to be in synchrony with the environment, the physical differences in the speeds of light and sound, as well as stimuli from other modalities such as odors, must be...
متن کاملDetecting sub-second changes in brain activation patterns during interictal epileptic spike using simultaneous EEG-fMRI
OBJECTIVE Epileptic spikes are associated with rapidly changing brain activation involving the epileptic foci and other brain regions in the "epileptic network". We aim to resolve these activation changes using simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) recordings. METHODS Simultaneous EEG-fMRI recordings from 9 patients with epilepsy were used ...
متن کاملHow many neural oscillators we need on sub- and supra-second intervals processing in the primate brain
Processing of time intervals in short temporal ranges, typically in suband suprasecond intervals, is vital for the survival of primates and humans. Research evidence has already shown that the processing of suband supra-second intervals is subserved by different neural mechanisms (Buhusi and Meck, 2005). In the domain of time perception, one outstanding scientific question remains to be solved ...
متن کاملDuration Adaptation Occurs Across the Sub- and Supra-Second Systems
After repetitive exposure to a stimulus of relatively short duration, a subsequent stimulus of long duration is perceived as being even longer, and after repetitive exposure to a stimulus of relatively long duration, a subsequent stimulus of short duration is perceived as being even shorter. This phenomenon is called duration adaptation, and has been reported only for sub-second durations. We e...
