A supramolecular assembly of cone‐specific G‐protein and cryptochrome 4a on lipid bilayer

open access: yesThe FEBS Journal, EarlyView.
Immobilized phospholipid bilayers on a sensor chip surface serve as membrane platform to investigate critical protein–lipid and protein–protein interaction processes by surface plasmon resonance. The putative magnetoreceptor cryptochrome 4a and the myristoylated cone‐specific G‐protein α‐subunit (Gtα) bind with high affinity to immobilized lipid ...

The what, which, when, why and who of Off responses in the auditory system

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this article, we will first review ‘What’ different mechanisms are involved in the generation of Off responses at the sub‐cortical and cortical level of the auditory system. Then, we evaluate ‘Which’ stimulus properties elicit Off responses at the different levels of the auditory system.

Anthropogenic Nest Cavities Used by Snow Buntings in an Urban Arctic Landscape

open access: yesEcology and Evolution
Northern and Arctic ecosystems are experiencing rapid climate change, and simultaneously, human populations in the North are growing and centralizing. The Snow Bunting (Plectrophenax nivalis) is a Holarctic‐breeding songbird and abundant in urban Iqaluit

11β-HSD Types 1 and 2 in the Songbird Brain

open access: yesFrontiers in Endocrinology, 2018
Glucocorticoid (GC) hormones act on the brain to regulate diverse functions, from behavior and homeostasis to the activity of the hypothalamic–pituitary–adrenal axis.

Epigenetic‐Based Evidence for Distinct Effects of Age, Sex, and Experience in Developmental Critical Period Learning

open access: yesDevelopmental Neurobiology, Volume 86, Issue 3, July 2026.
ABSTRACT Although much is known about the encoding of experience, how the brain organizes neural circuits capable of learning and memory formation is largely unstudied. Canonical critical periods emerge from a convergence of maturation‐ and experience‐dependent processes.

Cross-scale habitat selection reveals within-stand structural requirements for fledgling Golden-winged Warblers

open access: yesAvian Conservation and Ecology, 2021
The post-fledging period remains one of the most understudied portions of the avian lifecycle despite the fact that fledglings require resources distinct from those used during nesting.

Oculomotor learning revisited: a model of reinforcement learning in the basal ganglia incorporating an efference copy of motor actions

open access: yesFrontiers in Neural Circuits, 2012
In its simplest formulation, reinforcement learning is based on the idea that if an action taken in a particular context is followed by a favorable outcome, then, in the same context, the tendency to produce that action should be strengthened, or ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Exotic plants and other habitat characteristics do not impact Veery reproductive success at multiple spatial scales in northeastern Pennsylvania

open access: yesAvian Conservation and Ecology
It is expected that birds have evolved nest site preferences that, on average, lead to positive fitness outcomes. It is possible, however, that mismatches occur between these preferences and reproductive success when a population experiences sudden ...
