Postsynaptic Ca2+, but not cumulative depolarization, is necessary for the induction of associative plasticity in Hermissenda [PDF]

open access: yes, 1993
The neuronal modifications that underlie associative memory in Hermissenda have their origins in a synaptic interaction between the visual and vestibular systems, and can be mimicked by contiguous in vitro stimulation of these converging pathways. At the

SU(2)-invariant depolarization of quantum states of light [PDF]

open access: yes, 2013
We develop an SU(2)-invariant approach to the depolarization of quantum systems as the effect of random unitary SU(2) transformations. From it we derive an SU(2)-invariant Markovian master equation.

Acetylcholine Depolarizes Barnacle Photoreceptors [PDF]

open access: yesJournal of Experimental Biology, 1985
ABSTRACT A variety of vertebrate and invertebrate sensory cells are known to be sensitive to acetylcholine (ACh), although the purpose of ACh receptors on these cells is not understood. Acetylcholine elicits action potentials from the sensory cell of the crayfish stretch receptor organ, which receives inhibitory but not excitatory ...

User Influence on Polarization Characteristics in Off-Body Channels

open access: yesIEEE Access, 2020
This article investigates the impact of the user's body on wearable antenna radiation characteristics and the consequent effects on the off-body channel, with the focus on the polarization aspect.

Gravitational depolarization of ultracold neutrons: comparison with data [PDF]

open access: yes, 2015
We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a variety of vertical magnetic-field gradients.

Extension and Limits of Depolarization-Fringe Contrast Roughness Method in Sub-Micron Domain

open access: yesSensors, 2021
To guarantee quality standards for the industry, surface properties, particularly those of roughness, must be considered in many areas of application. Today, several methods are available on the market, but some damage the surface to be tested as they ...

Disease Phenotypes and Mechanisms of iPSC-Derived Cardiomyocytes From Brugada Syndrome Patients With a Loss-of-Function SCN5A Mutation

open access: yesFrontiers in Cell and Developmental Biology, 2020
Brugada syndrome (BrS) is one of the major causes of sudden cardiac death in young people, while the underlying mechanisms are not completely understood.

Calcium-independent inhibitory G-protein signaling induces persistent presynaptic muting of hippocampal synapses [PDF]

open access: yes, 2011
Adaptive forms of synaptic plasticity that reduce excitatory synaptic transmission in response to prolonged increases in neuronal activity may prevent runaway positive feedback in neuronal circuits.

Evaluation of the Relationship between T2*CMR and Cardiac Depolarization and Repolarization Parameters in Beta-Thalassemia Patients [PDF]

open access: yesJournal of Kerman University of Medical Sciences
Background: Cardiac iron overload causes severe cardiac complications and is a leading cause of death in beta-thalassemia major patient. T2*CMR can detect preclinical cardiac iron overload.

Lidar Observed Optical Properties of Tropical Cirrus Clouds Over Gadanki Region

open access: yesFrontiers in Earth Science, 2020
The presence of cirrus cloud has its impact on the earth’s radiation budget. In order to study the effect of cirrus clouds in the tropical regions, it is essential to understand, and characterize their optical properties.
