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 ...
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. ...
Evolutionary genomics and adaptive evolution of the Hedgehog gene family (Shh, Ihh and Dhh) in vertebrates.
(PLoS One, 2014)
The Hedgehog (Hh) gene family codes for a class of secreted proteins composed of two active domains that act as signalling molecules during embryo development, namely for the development of the nervous and skeletal systems ...
Comparative genomics reveals insights into avian genome evolution and adaptation
Association between the oxytocin receptor (OXTR) gene and mesolimbic responses to rewards.
(Mol Autism, 2014-01-31)
BACKGROUND: There has been significant progress in identifying genes that confer risk for autism spectrum disorders (ASDs). However, the heterogeneity of symptom presentation in ASDs impedes the detection of ASD risk genes. ...
Core and region-enriched networks of behaviorally regulated genes and the singing genome.
Songbirds represent an important model organism for elucidating molecular mechanisms that link genes with complex behaviors, in part because they have discrete vocal learning circuits that have parallels with those that ...
Complex evolutionary trajectories of sex chromosomes across bird taxa.
Sex-specific chromosomes, like the W of most female birds and the Y of male mammals, usually have lost most genes owing to a lack of recombination. We analyze newly available genomes of 17 bird species representing the avian ...
Advances in understanding mechanisms of thalamic relays in cognition and behavior.
(J Neurosci, 2014-11-12)
The main impetus for a mini-symposium on corticothalamic interrelationships was the recent number of studies highlighting the role of the thalamus in aspects of cognition beyond sensory processing. The thalamus contributes ...
Basal ganglia function, stuttering, sequencing, and repair in adult songbirds.
(Sci Rep, 2014-10-13)
A pallial-basal-ganglia-thalamic-pallial loop in songbirds is involved in vocal motor learning. Damage to its basal ganglia part, Area X, in adult zebra finches has been noted to have no strong effects on song and its function ...
