Acoustic event detection for multiple overlapping similar sources

open access: yes, 2015
Many current paradigms for acoustic event detection (AED) are not adapted to the organic variability of natural sounds, and/or they assume a limit on the number of simultaneous sources: often only one source, or one source of each type, may be active ...

Vocal learning promotes patterned inhibitory connectivity. [PDF]

open access: yes, 2017
Skill learning is instantiated by changes to functional connectivity within premotor circuits, but whether the specificity of learning depends on structured changes to inhibitory circuitry remains unclear.

Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

Sexual Dimorphism in the Early Embryogenesis in Zebra Finches

open access: yesPLoS ONE, 2014
Sex-specific gene expression before the onset of gonadogensis has been documented in embryos of mammals and chickens. In several mammalian species, differences in gene expression are accompanied by faster growth of pre-implantation male embryos. Here we asked whether avian embryos before gonadal differentiation are also sex-dimorphic in size and what ...

Cannabinoid exposure during zebra finch sensorimotor vocal learning persistently alters expression of endocannabinoid signaling elements and acute agonist responsiveness

open access: yesBMC Neuroscience, 2011
Background Previously we have found that cannabinoid treatment of zebra finches during sensorimotor stages of vocal development alters song patterns produced in adulthood.

Neural expression and post-transcriptional dosage compensation of the steroid metabolic enzyme 17β-HSD type 4

open access: yesBMC Neuroscience, 2010
Background Steroids affect many tissues, including the brain. In the zebra finch, the estrogenic steroid estradiol (E2) is especially effective at promoting growth of the neural circuit specialized for song.

Individual recognition of opposite sex vocalizations in the zebra finch

open access: yesScientific Reports, 2017
Individual vocal recognition plays an important role in the social lives of many vocally active species. In group-living songbirds the most common vocalizations during communal interactions are low-intensity, soft, unlearned calls.

Fundamental constraints in synchronous muscle limit superfast motor control in vertebrates

open access: yeseLife, 2017
Superfast muscles (SFMs) are extremely fast synchronous muscles capable of contraction rates up to 250 Hz, enabling precise motor execution at the millisecond time scale.
