Dopamine receptors in a songbird brain.
(J Comp Neurol, 2010-03-15)
Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song ...
Global view of the functional molecular organization of the avian cerebrum: mirror images and functional columns.
(J Comp Neurol, 2013-11)
Based on quantitative cluster analyses of 52 constitutively expressed or behaviorally regulated genes in 23 brain regions, we present a global view of telencephalic organization of birds. The patterns of constitutively expressed ...
Rudimentary substrates for vocal learning in a suboscine.
(Nat Commun, 2013)
Vocal learning has evolved in only a few groups of mammals and birds. The key neuroanatomical and behavioural links bridging vocal learners and non-learners are still unknown. Here we show that a non-vocal-learning suboscine, ...
The dusp1 immediate early gene is regulated by natural stimuli predominantly in sensory input neurons.
(J Comp Neurol, 2010-07-15)
Many immediate early genes (IEGs) have activity-dependent induction in a subset of brain subdivisions or neuron types. However, none have been reported yet with regulation specific to thalamic-recipient sensory neurons of ...
Radioactive in situ hybridization for detecting diverse gene expression patterns in tissue.
(J Vis Exp, 2012-04-27)
Knowing the timing, level, cellular localization, and cell type that a gene is expressed in contributes to our understanding of the function of the gene. Each of these features can be accomplished with in situ hybridization ...
Specialized motor-driven dusp1 expression in the song systems of multiple lineages of vocal learning birds.
(PLoS One, 2012)
Mechanisms for the evolution of convergent behavioral traits are largely unknown. Vocal learning is one such trait that evolved multiple times and is necessary in humans for the acquisition of spoken language. Among birds, ...
