Article Synopsis
- - The study investigates how testosterone affects song production in adult female canaries, which typically do not sing, by analyzing gene regulatory networks in a brain area responsible for song control (HVC) over a period of time after hormone treatment.
- - Female canaries started to vocalize within four days of receiving testosterone, with both song complexity and the brain region's volume increasing over a two-week period.
- - The researchers found that a significant number of genes (over 9,900) were differentially expressed during this time, indicating a complex and dynamic relationship between testosterone and the neural mechanisms involved in song development.
Birdsong is a precisely timed animal behavior. The connectivity of song premotor neural networks has been proposed to underlie the temporal patterns of neuronal activity that control vocal muscle movements during singing. Although the connectivity of premotor nuclei via chemical synapses has been characterized, electrical synapses and their molecular identity remain unexplored.

Here, we aimed at establishing a genome-wide DNA methylation map of the zebra finch genome, a model organism in neuroscience, as well as identifying putatively epigenetically regulated genes. RNA- and MethylCap-seq experiments were performed on two zebra finch cell lines in presence or absence of 5-aza-2'-deoxycytidine induced demethylation.
