DOI: 10.1002/hbm.24469
Abstract: Gamma oscillations facilitate information processing by shaping the excitatory input/output of neuronal populations. Recent studies in humans and nonhuman primates have shown that strong excitatory drive to the visual cortex leads to suppression of induced… read more here.

DOI: 10.1016/j.clinph.2018.04.729
Abstract: Carrying conversations in public spaces with a plethora of competing sensory inputs demands flexible interactions between attention and perception for selectively processing goal-relevant information. We postulate that the fronto-striatal network plays a key role in… read more here.

DOI: 10.1093/cercor/bhw083
Abstract: Abstract Natural sounds exhibit statistical variation in their spectrotemporal structure. This variation is central to identification of unique environmental sounds and to vocal communication. Using limited resources, the auditory system must create a faithful representation… read more here.

DOI: 10.1109/tcsi.2022.3150165
Abstract: Including local automatic gain control (AGC) circuitry into a silicon cochlea design has been challenging because of transistor mismatch and model complexity. To address this, we present an alternative system-level algorithm that implements channel-specific AGC… read more here.

DOI: 10.1152/jn.00681.2017
Abstract: The excitotoxic theory of Parkinson’s disease (PD) hypothesizes that a pathophysiological degeneration of dopaminergic neurons stems from neural hyperactivity at early stages of disease, leading to mitochondrial stress and cell death. Recent research has harnessed… read more here.

DOI: 10.1152/jn.00694.2016
Abstract: In the olfactory bulb, lateral inhibition mediated by local juxtaglomerular interneurons has been proposed as a gain control mechanism, important for decorrelating odorant responses. Among juxtaglomerular interneurons, short axon cells are unique as dual-transmitter neurons… read more here.
