Decision time, slow inhibition, and theta rhythm [PDF]

open access: yes, 2010
In this paper, we examine decision making in a spiking neuronal network and show that longer time constants for the inhibitory neurons can decrease the reaction times and produce theta rhythm.We analyze the mechanism and find that the spontaneous firing

Selective disruption of stimulus-reward learning in glutamate receptor gria 1 knockout mice. [PDF]

open access: yes, 2003
Glutamatergic neurotransmission via AMPA receptors has been an important focus of studies investigating neuronal plasticity. AMPA receptor glutamate receptor 1 (GluR1) subunits play a critical role in long-term potentiation (LTP).

Cell biological mechanisms of activity-dependent synapse to nucleus translocation of CRTC1 in neurons. [PDF]

open access: yes, 2015
Previous studies have revealed a critical role for CREB-regulated transcriptional coactivator (CRTC1) in regulating neuronal gene expression during learning and memory. CRTC1 localizes to synapses but undergoes activity-dependent nuclear translocation to

Postsynaptic Synaptotagmins Mediate AMPA Receptor Exocytosis During LTP

open access: yesNature, 2017
Strengthening of synaptic connections by NMDA (N-methyl-d-aspartate) receptor-dependent long-term potentiation (LTP) shapes neural circuits and mediates learning and memory.

Dissecting the Activation of AMPA Receptors [PDF]

open access: yesBiophysical Journal, 2013
Ionotropic glutamate receptors are tetrameric ion channels that are activated by the neurotransmitter glutamate at excitatory synapses. It is known that after the binding of glutamate, the AMPA-subtype of glutamate receptors transits through distinct functional states to become fully activated, however, the conformations sampled by the tetramer during ...

AMPA Receptor Activation [PDF]

open access: yesNeuron, 2004
AMPA receptors are tetramers assembled as a dimer-of-dimers with a 2-fold rotational symmetry in their extracellular domains. Two papers in this issue of Neuron, by Horning and Mayer and Sobolevsky et al., provide complementary data that extend this view and highlight the role of dimers in channel gating.

Light‐Gated Amine Exchange in Diarylethene‐Crosslinked Microgels

open access: yesAngewandte Chemie, EarlyView.
Integrating aniline‐type diarylethenes as core‐enriched crosslinkers in poly(N‐vinylcaprolactam) based microgels enables photomodulation of their responsivity towards temperature and pH as well as covalent binding and release of functional amines via light‐gated amine exchange reaction.

Hypothalamic excitatory amino acid receptors mediate stress-induced tachycardia in rats [PDF]

open access: yes, 1992
The role of hypothalamic excitatory amino acid (EAA) receptors in mediating the cardiovascular response to stress was examined using conscious chronically instrumented rats.

Clathrin-Independent Trafficking of AMPA Receptors [PDF]

open access: yesThe Journal of Neuroscience, 2015
Membrane trafficking of AMPA receptors (AMPARs) is critical for neuronal function and plasticity. Although rapid forms of AMPAR internalization during long-term depression (LTD) require clathrin and dynamin, the mechanisms governing constitutive AMPAR turnover and internalization of AMPARs during slow homeostatic forms of synaptic plasticity remain ...

Infrared Neural Stimulation Elicits Distinct Molecular Pathways in Astrocytes Based on Laser Pulse Parameters

open access: yesAdvanced Biology, EarlyView.
Infrared (IR) light evokes distinct calcium and water transport responses in astrocytes, depending on stimulation duration and protocol. This study uses widefield imaging and pharmacology to reveal differential engagement of astroglial signaling pathways.
