Female Zebra Finches Smell Their Eggs
PLOS ONE, 2016 Parental investment in unrelated offspring seems maladaptive from an evolutionary perspective, due to the costs of energy and resources that cannot be invested in related offspring at the same time. Therefore selection should favour mechanisms to discriminate between own and foreign offspring.

The potential role of Arhgef33 RhoGEF in foveal development in the zebra finch retina
Scientific Reports, 2020 The fovea is a pit formed in the center of the retina that enables high-acuity vision in certain vertebrate species. While formation of the fovea fascinates many researchers, the molecular mechanisms underlying foveal development are poorly understood ...

eLife, 2021 Increases in the scale and complexity of behavioral data pose an increasing challenge for data analysis. A common strategy involves replacing entire behaviors with small numbers of handpicked, domain-specific features, but this approach suffers from ...

Vocal Tract Articulation in Zebra Finches
PLoS ONE, 2010 Birdsong and human vocal communication are both complex behaviours which show striking similarities mainly thought to be present in the area of development and learning. Recent studies, however, suggest that there are also parallels in vocal production mechanisms.

THE WAVELENGTH SENSITIVITY FUNCTION FOR THE ZEBRA FINCH [PDF]
Journal of General Physiology, 1942 With lights of different spectral compositions filtered from a white, the flicker response contours for the zebra finch are found to exhibit the same general kind of relationship between flicker excitation and wavelength as is found in the case of man ("cone" contours), with the same filters.

Resurgent Na+ currents promote ultrafast spiking in projection neurons that drive fine motor control
Nature Communications, 2021 The zebra finch robust nucleus of the arcopallium (RA) directs singing by providing descending projections to brainstem motor neurons. The authors show that electrophysiological characteristics of RA neurons rely on resurgent Na+ currents that emerge ...

Dopamine receptors in a songbird brain. [PDF]
, 2010 Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior.

Maternal effects underlie ageing costs of growth in the zebra finch (Taeniopygia guttata). [PDF]
PLoS ONE, 2014 Maternal effects provide a mechanism to adapt offspring phenotype and optimize the mother's fitness to current environmental conditions. Transferring steroids to the yolk is one way mothers can translate environmental information into potential adaptive ...

A comment on "A fast L_p spike alignment metric" by A. J. Dubbs, B. A. Seiler and M. O. Magnasco [arXiv:0907.3137] [PDF]
, 2009 Measuring the transmitted information in metric-based clustering has become something of a standard test for the performance of a spike train metric. In this comment, the recently proposed L_p Victor-Purpura metric is used to cluster spiking responses to

Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...
