Breathing-driven prefrontal oscillations regulate maintenance of conditioned-fear evoked freezing independently of initiation

open access: yesNature Communications, 2021
Combining optogenetics, behavioral modelling and neural population analysis, the authors show in mice that during fear-related freezing the olfactory bulb transmits 4 Hz breathing rhythm to the prefrontal cortex where this oscillation organizes local ...

AMPA Receptor Phosphorylation and Synaptic Colocalization on Motor Neurons Drive Maladaptive Plasticity below Complete Spinal Cord Injury. [PDF]

open access: yes, 2015
Clinical spinal cord injury (SCI) is accompanied by comorbid peripheral injury in 47% of patients. Human and animal modeling data have shown that painful peripheral injuries undermine long-term recovery of locomotion through unknown mechanisms ...

Ancestral glycoprotein hormone-receptor pathway controls growth in C. elegans

open access: yesFrontiers in Endocrinology, 2023
In vertebrates, thyrostimulin is a highly conserved glycoprotein hormone that, besides thyroid stimulating hormone (TSH), is a potent ligand of the TSH receptor.

Fluctuating population dynamics promotes the evolution of phenotypic plasticity [PDF]

open access: yes, 2007
An increasing number of studies are showing evidence in support of sympatric speciation. One basic question remains, however. When a population has undergone a branching in its phenotype, is this due to an evolutionary branching in the underlying ...

Uncoupled material model of ductile fracture with directional plasticity [PDF]

open access: yes, 2017
Proposed paper deals with the application of plastic response with directional distortional hardening (DDH) in uncoupled ductile fracture model and comparison of the results with the same ductile fracture model based on isotropic J2 plasticity.

Size effects and idealized dislocation microstructure at small scales: predictions of a phenomenological model of Mesoscopic Field Dislocation Mechanics: Part I

open access: yes, 2005
A Phenomenological Mesoscopic Field Dislocation Mechanics (PMFDM) model is developed, extending continuum plasticity theory for studying initial-boundary value problems of small-scale plasticity.

The C-terminal helix 9 motif in rat cannabinoid receptor type 1 regulates axonal trafficking and surface expression

open access: yeseLife, 2019
Cannabinoid type one receptor (CB1R) is only stably surface expressed in axons, where it downregulates neurotransmitter release. How this tightly regulated axonal surface polarity is established and maintained is unclear.

Association between attention-deficit/hyperactivity disorder symptom severity and white matter integrity moderated by in-scanner head motion

open access: yesTranslational Psychiatry, 2022
Attention-deficit/hyperactivity disorder (ADHD) is a common and debilitating neurodevelopmental disorder associated with various negative life impacts.

Somatosensory alpha oscillations gate perceptual learning efficiency

open access: yesNature Communications, 2019
Alpha power is known to play an important role in cognition and perception, but we do not understand the link between alpha power and perceptual learning efficacy.
