Abstract
Contingent negative variation (CNV) topography, hemispheric asymmetry and time-course were investigated in healthy subjects and non-medicated paranoid schizophrenic patients in two antisaccade paradigms with the short (800-1000 ms) and long (1200-1400 ms) durations of the fixation pe...

Abstract
We used two-photon RuBi-Glutamate uncaging to optically map how the largest population of cortical interneurons, the parvalbumin-positive cells (PV+), are connected to pyramidal cells (PCs) in mouse neocortex. We found locally dense connectivity from PV+ interneurons onto PCs across cortical areas a...

Abstract
We contrasted the connection patterns of parvalbumin-immunoreactive cells in two functionally distinct cortical regions: the tonotopic, narrowly frequency-tuned module [central narrow band (cNB)] of cat central primary auditory cortex (AI) and the nontonotopic, broadly tuned second auditory field (A...

Abstract
We recorded single-unit activity and local field potential from three MTL areas (hippocampus and entorhinal and perirhinal cortex) and visual area TE as monkeys performed a temporal-order memory task. Hippocampus provided incremental timing signals from one item presentation to the next, whereas per...

We designed a functional MRI task capable of imaging FL activity in individuals, including the SGC region, using a transient sadness paradigm. We sought to develop a method that may better detect individual differences of FL subregions related to sadness, since this region has been implicated to sho...

The discovery of the period gene mutants in 1971 provided the first evidence that daily rhythms in the sleep-wake cycle of a multicellular organism, the fruit fly Drosophila melanogaster, had an underlying genetic basis. Subsequent research has established that the biological clock mechanism in flies...
