Social context-dependent singing-regulated dopamine.
(J Neurosci, 2006-08-30)
Like the mammalian striatum, the songbird striatum receives dense dopaminergic input from the midbrain ventral tegmental area-substantia nigra pars compacta complex. The songbird striatum also contains a unique vocal nucleus, ...
A corollary discharge for perceptual stability
A molecular neuroethological approach for identifying and characterizing a cascade of behaviorally regulated genes.
(Proc Natl Acad Sci U S A, 2006-10-10)
Songbirds have one of the most accessible neural systems for the study of brain mechanisms of behavior. However, neuroethological studies in songbirds have been limited by the lack of high-throughput molecular resources ...
Influence of the thalamus on spatial visual processing in frontal cortex.
Each of our movements activates our own sensory receptors, and therefore keeping track of self-movement is a necessary part of analysing sensory input. One way in which the brain keeps track of self-movement is by monitoring ...
VOCALIZATIONS AND ASSOCIATED BEHAVIORS OF THE SOMBRE HUMMINGBIRD (APHANTOCHROA CIRRHOCHLORIS) AND THE RUFOUS-BREASTED HERMIT (GLAUCIS HIRSUTUS).
Vocal behavior in tropical hummingbirds is a new area of study. Here, we present findings on the vocalizations and associated behaviors of two species: Sombre Hummingbird (Aphantochroa cirrhochloris) and Rufous-breasted ...
Smoothened signal transduction is promoted by G protein-coupled receptor kinase 2.
(Mol Cell Biol, 2006-10)
Deregulation of the Sonic hedgehog pathway has been implicated in an increasing number of human cancers. In this pathway, the seven-transmembrane (7TM) signaling protein Smoothened regulates cellular proliferation ...
Computational inference of neural information flow networks.
(PLoS Comput Biol, 2006-11-24)
Determining how information flows along anatomical brain pathways is a fundamental requirement for understanding how animals perceive their environments, learn, and behave. Attempts to reveal such neural information flow ...
Spending on postapproval drug safety.
(Health Aff (Millwood), 2006-03)
Withdrawals of high-profile pharmaceuticals have focused attention on post-approval safety surveillance. There have been no systematic assessments of spending on postapproval safety. We surveyed drug manufacturers regarding ...
Concurrent use of methamphetamine, MDMA, LSD, ketamine, GHB, and flunitrazepam among American youths.
(Drug and alcohol dependence, 2006-09)
The magnitude and the characteristics of the use of methamphetamine, MDMA (Ecstasy), LSD (d-lysergic acid diethylamide), ketamine, GHB (gamma-hydroxybutyrate), and flunitrazepam (Rohypnol) were examined in a probability ...
Use of alcohol treatment and mental health services among adolescents with alcohol use disorders.
(Psychiatric services (Washington, D.C.), 2006-01)
OBJECTIVE:This study examined the use of and perceived need for alcohol treatment services among adolescents (aged 12 to 17 years) who received mental health services in the previous year compared with same-aged adolescents ...
