Dopamine Receptors in a Songbird Brain [PDF]

Journal of Comparative Neurology, 2010
AbstractDopamine 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 nucleus area X, and the levels depend on social contexts of undirected and directed singing.

Neural activity in cortico-basal ganglia circuits of juvenile songbirds encodes performance during goal-directed learning

eLife, 2017
Cortico-basal ganglia circuits are thought to mediate goal-directed learning by a process of outcome evaluation to gradually select appropriate motor actions.

Song Processing in the Zebra Finch Auditory Forebrain Reflects Asymmetric Sensitivity to Temporal and Spectral Structure

Frontiers in Neuroscience, 2017
Despite being commonly referenced throughout neuroscientific research on songbirds, reports of hemispheric specialization in the processing of song remain controversial.

Mismatch Responses Evoked by Sound Pattern Violation in the Songbird Forebrain Suggest Common Auditory Processing With Human

Frontiers in Physiology, 2022
Learning sound patterns in the natural auditory scene and detecting deviant patterns are adaptive behaviors that aid animals in predicting future events and behaving accordingly.

Forest Policy Scenario Analysis: Sensitivity of Songbird Community to Changes in Forest Cover Amount and Configuration

Avian Conservation and Ecology, 2007
Changes in mature forest cover amount, composition, and configuration can be of significant consequence to wildlife populations. The response of wildlife to forest patterns is of concern to forest managers because it lies at the heart of such competing ...

Prenatal Valproic Acid Exposure Affects Song Learning in Zebra Finches: A Potential Model for Vocal Development in Autism

Life
Autism spectrum disorder (ASD) encompasses a range of neurodevelopmental conditions characterized by impairments in social abilities and communication. Studying appropriate animal models can enhance our understanding of the neural mechanisms underlying ...

Crop type influences edge effects on the reproduction of songbirds in sagebrush habitat near agriculture

Avian Conservation and Ecology, 2014
Extensive fragmentation of the sagebrush shrubsteppe of western North America could be contributing to observed population declines of songbirds in sagebrush habitat.

A loss of heterozygosity, a loss in competition? The effects of inbreeding, pre‐ and postnatal conditions on nestling development

Ecology and Evolution, 2016
The early developmental trajectory is affected by genetic and environmental factors that co‐depend and interact often in a complex way. In order to distinguish their respective roles, we used canaries (Serinus canaria) of different genetic backgrounds ...

Short-term weather patterns influence avian body condition during the breeding season

Frontiers in Ecology and Evolution, 2023
Despite a large body of literature investigating the effects of long-term climate trends on birds, the effects of short-term weather on individual body condition are less established.
