Physiological Plasticity of Neural-Crest-Derived Stem Cells in the Adult Mammalian Carotid Body [PDF]

, 2017
Adult stem cell plasticity, or the ability of somatic stem cells to cross boundaries and differentiate into unrelated cell types, has been amatter of debate in the last decade.

Optimal storage and recall with biologically plausible synapses [PDF]

, 2011
Synaptic plasticity is widely accepted to underlie learning and memory. Yet, models of associative networks with biologically plausible synapses fail to match brain performance: memories stored in such networks are quickly overwritten by ongoing ...

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

Frontiers 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.

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

eLife, 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.

Effects of Synaptic and Myelin Plasticity on Learning in a Network of Kuramoto Phase Oscillators [PDF]

, 2019
Models of learning typically focus on synaptic plasticity. However, learning is the result of both synaptic and myelin plasticity. Specifically, synaptic changes often co-occur and interact with myelin changes, leading to complex dynamic interactions ...

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

Nature 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 ...

Synaptic plasticity in medial vestibular nucleus neurons: comparison with computational requirements of VOR adaptation [PDF]

, 2010
Background: Vestibulo-ocular reflex (VOR) gain adaptation, a longstanding experimental model of cerebellar learning, utilizes sites of plasticity in both cerebellar cortex and brainstem.

Somatosensory alpha oscillations gate perceptual learning efficiency

Nature 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.

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

, 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.
