Probing Computation in the Primate Visual System at Single-Cone Resolution.
(Annual review of neuroscience, 2019-03-11)
Daylight vision begins when light activates cone photoreceptors in the retina, creating spatial patterns of neural activity. These cone signals are then combined and processed in downstream neural circuits, ultimately producing ...
Strategic allocation of attention reduces temporally predictable stimulus conflict.
(J Cogn Neurosci, 2012-09)
Humans are able to continuously monitor environmental situations and adjust their behavioral strategies to optimize performance. Here we investigate the behavioral and brain adjustments that occur when conflicting stimulus ...
Bird song systems: Evolution
This article presents the vocal and auditory pathways of vocal-learning birds and a hypothesis about their evolution. These pathways control the ability to produce learned song in the few groups of birds that have vocal ...
The dynamics of proactive and reactive cognitive control processes in the human brain.
(J Cogn Neurosci, 2014-05)
In this study, we leveraged the high temporal resolution of EEG to examine the neural mechanisms underlying the flexible regulation of cognitive control that unfolds over different timescales. We measured behavioral and ...
A Foxp2 Mutation Implicated in Human Speech Deficits Alters Sequencing of Ultrasonic Vocalizations in Adult Male Mice.
(Front Behav Neurosci, 2016)
Development of proficient spoken language skills is disrupted by mutations of the FOXP2 transcription factor. A heterozygous missense mutation in the KE family causes speech apraxia, involving difficulty producing words ...
Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
(PLoS One, 2008-08-13)
The widely used blood oxygenation level dependent (BOLD) signal during brain activation, as measured in typical fMRI methods, is composed of several distinct phases, the last of which, and perhaps the least understood, is ...
Neuroepithelial circuit formed by innervation of sensory enteroendocrine cells
(JOURNAL OF CLINICAL INVESTIGATION, 2015-02)
TRPV channel-mediated calcium transients in nociceptor neurons are dispensable for avoidance behaviour.
(Nat Commun, 2014-09-02)
Animals need to sense and react to potentially dangerous environments. TRP ion channels participate in nociception, presumably via Ca(2+) influx, in most animal species. However, the relationship between ion permeation and ...
Anti-inflammatory effects of progesterone in lipopolysaccharide-stimulated BV-2 microglia.
(PLoS One, 2014)
Female sex is associated with improved outcome in experimental brain injury models, such as traumatic brain injury, ischemic stroke, and intracerebral hemorrhage. This implies female gonadal steroids may be neuroprotective. ...
The Rational Adolescent: Strategic Information Processing during Decision Making Revealed by Eye Tracking.
(Cogn Dev, 2015-10)
Adolescence is often viewed as a time of irrational, risky decision-making - despite adolescents' competence in other cognitive domains. In this study, we examined the strategies used by adolescents (N=30) and young adults ...
