A neurophysiological study into the foundations of tonal harmony.
(Neuroreport, 2009-02-18)Our findings provide magnetoencephalographic evidence that the mismatch-negativity response to two-note chords (dyads) is modulated by a combination of abstract cognitive differences and lower-level differences in the auditory ... -
Action video game playing is associated with improved visual sensitivity, but not alterations in visual sensory memory.
(Atten Percept Psychophys, 2013-08)Action video game playing has been experimentally linked to a number of perceptual and cognitive improvements. These benefits are captured through a wide range of psychometric tasks and have led to the proposition that action ... -
Behavior genetics and postgenomics.
(Behav Brain Sci, 2012-10)The science of genetics is undergoing a paradigm shift. Recent discoveries, including the activity of retrotransposons, the extent of copy number variations, somatic and chromosomal mosaicism, and the nature of the epigenome ... -
Cell type-specific changes in retinal ganglion cell function induced by rod death and cone reorganization in rats.
(Journal of neurophysiology, 2017-07)We have determined the impact of rod death and cone reorganization on the spatiotemporal receptive fields (RFs) and spontaneous activity of distinct retinal ganglion cell (RGC) types. We compared RGC function between healthy ... -
Changes in Brain Resting-state Functional Connectivity Associated with Peripheral Nerve Block: A Pilot Study.
(Anesthesiology, 2016-08)BACKGROUND: Limited information exists on the effects of temporary functional deafferentation (TFD) on brain activity after peripheral nerve block (PNB) in healthy humans. Increasingly, resting-state functional connectivity ... -
Differential expression of glutamate receptors in avian neural pathways for learned vocalization.
(J Comp Neurol, 2004-08-09)Learned vocalization, the substrate for human language, is a rare trait. It is found in three distantly related groups of birds-parrots, hummingbirds, and songbirds. These three groups contain cerebral vocal nuclei for learned ... -
Diffusion Tensor Imaging Biomarkers of Stem Cell Therapy Efficacy in Pediatric Cerebral Palsy
(2012)Cerebral palsy (CP) is a non-progressive sensory-motor disorder and is one of the most costly and debilitating chronic pediatric conditions, affecting 2-3 out of 1000 children in the United States. To better understand the ... -
FoxP2 expression in avian vocal learners and non-learners.
(J Neurosci, 2004-03-31)Most vertebrates communicate acoustically, but few, among them humans, dolphins and whales, bats, and three orders of birds, learn this trait. FOXP2 is the first gene linked to human speech and has been the target of positive ... -
Mechanisms of specificity in neuronal activity-regulated gene transcription.
(2012)In the nervous system, activity-regulated gene transcription is one of the fundamental processes responsible for orchestrating proper brain development–a process that in humans takes over 20 years. Moreover, activity-dependent ... -
Memory maintenance in synapses with calcium-based plasticity in the presence of background activity.
(PLoS Comput Biol, 2014-10)Most models of learning and memory assume that memories are maintained in neuronal circuits by persistent synaptic modifications induced by specific patterns of pre- and postsynaptic activity. For this scenario to be viable, ... -
Neuronal Adaptation: Tired Neurons or Wired Networks?
(Trends in neurosciences, 2017-03)Neuronal adaptation - time-dependent modulation of sensory responses following sequential stimuli - is thought to be a consequence of synaptic plasticity. But recent, empirically-grounded, modeling by Quiroga and colleagues ... -
Optimal properties of analog perceptrons with excitatory weights.
(PLoS Comput Biol, 2013)The cerebellum is a brain structure which has been traditionally devoted to supervised learning. According to this theory, plasticity at the Parallel Fiber (PF) to Purkinje Cell (PC) synapses is guided by the Climbing fibers ... -
Regulation of spine structural plasticity by Arc/Arg3.1.
(Seminars in cell & developmental biology, 2018-05)Dendritic spines are actin-rich, postsynaptic protrusions that contact presynaptic terminals to form excitatory chemical synapses. These synaptic contacts are widely believed to be the sites of memory formation and information ... -
Sequential ionic and conformational signaling by calcium channels drives neuronal gene expression.
(Science, 2016-02-19)Voltage-gated CaV1.2 channels (L-type calcium channel α1C subunits) are critical mediators of transcription-dependent neural plasticity. Whether these channels signal via the influx of calcium ion (Ca(2+)), voltage-dependent ...
