Complex sequencing rules of birdsong can be explained by simple hidden Markov processes. [PDF]

PLoS ONE, 2011
Complex sequencing rules observed in birdsongs provide an opportunity to investigate the neural mechanism for generating complex sequential behaviors. To relate the findings from studying birdsongs to other sequential behaviors such as human speech and ...

Dynamic expression of cadherins regulates vocal development in a songbird. [PDF]

PLoS ONE, 2011
BACKGROUND: Since, similarly to humans, songbirds learn their vocalization through imitation during their juvenile stage, they have often been used as model animals to study the mechanisms of human verbal learning.

Shared mechanisms of auditory and non-auditory vocal learning in the songbird brain

eLife, 2022
Songbirds and humans share the ability to adaptively modify their vocalizations based on sensory feedback. Prior studies have focused primarily on the role that auditory feedback plays in shaping vocal output throughout life.

Comparative analysis of protocadherin-11 X-linked expression among postnatal rodents, non-human primates, and songbirds suggests its possible involvement in brain evolution. [PDF]

PLoS ONE, 2013
BACKGROUND: Protocadherin-11 is a cell adhesion molecule of the cadherin superfamily. Since, only in humans, its paralog is found on the Y chromosome, it is expected that protocadherin-11X/Y plays some role in human brain evolution or sex differences ...

Sequential learning and rule abstraction in Bengalese finches [PDF]

Animal Cognition, 2011
The Bengalese finch (Lonchura striata var. domestica) is a species of songbird. Males sing courtship songs with complex note-to-note transition rules, while females discriminate these songs when choosing their mate. The present study uses serial reaction time (RT) to examine the characteristics of the Bengalese finches' sequential behaviours beyond ...

Unsupervised Bayesian Ising Approximation for decoding neural activity and other biological dictionaries

eLife, 2022
The problem of deciphering how low-level patterns (action potentials in the brain, amino acids in a protein, etc.) drive high-level biological features (sensorimotor behavior, enzymatic function) represents the central challenge of quantitative biology ...

Myomatrix arrays for high-definition muscle recording

eLife, 2023
Neurons coordinate their activity to produce an astonishing variety of motor behaviors. Our present understanding of motor control has grown rapidly thanks to new methods for recording and analyzing populations of many individual neurons over time.

Songbirds can learn flexible contextual control over syllable sequencing

eLife, 2021
The flexible control of sequential behavior is a fundamental aspect of speech, enabling endless reordering of a limited set of learned vocal elements (syllables or words). Songbirds are phylogenetically distant from humans but share both the capacity for

Biological clocks as age estimation markers in animals: a systematic review and meta‐analysis

Biological Reviews, Volume 98, Issue 6, Page 1972-2011, December 2023., 2023
ABSTRACT Various biological attributes associated with individual fitness in animals change predictably over the lifespan of an organism. Therefore, the study of animal ecology and the work of conservationists frequently relies upon the ability to assign animals to functionally relevant age classes to model population fitness.

The carotenoid redshift: Physical basis and implications for visual signaling

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
Carotenoid pigments appear redder as the concentration of a pigment increases. The carotenoid redshift arises due to the asymmetrical reflectance spectra of carotenoid‐colored ornaments and the exponential attenuation of light. Structures that increase the path length of light through carotenoid pigment also cause a redshift, as we demonstrate in the ...
