Fear learning and aversive stimuli differentially change excitatory synaptic transmission in perisomatic inhibitory cells of the basal amygdala

open access: yesFrontiers in Cellular Neuroscience, 2023
Inhibitory circuits in the basal amygdala (BA) have been shown to play a crucial role in associative fear learning. How the excitatory synaptic inputs received by BA GABAergic interneurons are influenced by memory formation, a network parameter that may ...

Excitation Spectrum in the Friedberg-Lee Model [PDF]

open access: yes, 2001
The excitation spectrum of the nucleon with the spin 1/2 is examined by using the Friedberg-Lee model containing the constituent quark and the scalar meson. An appropriate way of quantization for the non-linear meson field is employed by taking account

Benchmark Angle-Differential Cross-Section Ratios for Excitation of the 4p5s Configuration in Krypton

open access: yesAtoms, 2021
Benchmark intensity ratio measurements of the energy loss lines of krypton for excitation of the 4p61S0→4p55s[3/2]2, 4p55s[3/2]1, 4p55s′[1/2]0, and 4p55s′[1/2]1 transitions are reported, these being the lowest electronic excitations for krypton.

Excited by fasting? NO [PDF]

open access: yesThe Journal of Physiology, 2014
Nitric oxide (NO) has multiple effects within the gastrointestinal (GI) system, including modulation of GI motility, mucosal function, inflammation and blood flow, as well as the excitability and responsiveness of vagal sensory afferents as well as vagal efferents. In this issue of The Journal of Physiology Kentish et al.

Interaction of Be4+ and Ground State Hydrogen Atom—Classical Treatment of the Collision

open access: yesAtoms, 2020
The interaction between Be4+ and hydrogen atom is studied using the three-body classical trajectory Monte Carlo method (CTMC) and the quasiclassical trajectory Monte Carlo method of Kirschbaum and Wilets (QTMC-KW).

Excitation control: balancing PSD-95 function at the synapse

open access: yesFrontiers in Molecular Neuroscience, 2008
Excitability of individual neurons dictates the overall excitation in specifi c brain circuits. This process is thought to be regulated by molecules that regulate synapse number, morphology and strength.

Hidden multiparticle excitation in weakly interacting Bose-Einstein Condensate

open access: yes, 2018
We investigate multiparticle excitation effect on a collective density excitation as well as a single-particle excitation in a weakly interacting Bose--Einstein condensate (BEC).

Evolution of the pygmy dipole resonance in nuclei with neutron excess

open access: yes, 2009
The electric dipole excitation of various nuclei is calculated with a Random Phase Approximation phenomenological approach. The evolution of the strength distribution in various groups of isotopes, oxygen, calcium, zirconium and tin, is studied.

Plasticity during Sleep Is Linked to Specific Regulation of Cortical Circuit Activity

open access: yesFrontiers in Neural Circuits, 2017
Sleep is thought to be involved in the regulation of synaptic plasticity in two ways: by enhancing local plastic processes underlying the consolidation of specific memories and by supporting global synaptic homeostasis.
