A Local Circuit Model of Learned Striatal and Dopamine Cell Responses under Probabilistic Schedules of Reward [PDF]

open access: yes, 2007
Before choosing, it helps to know both the expected value signaled by a predictive cue and the associated uncertainty that the reward will be forthcoming. Recently, Fiorillo et al.

Thalamic inputs to dorsomedial striatum are involved in inhibitory control: evidence from the five-choice serial reaction time task in rats [PDF]

open access: yes, 2017
Rationale Corticostriatal circuits are widely implicated in the top-down control of attention including inhibitory control and behavioural flexibility. However, recent neurophysiological evidence also suggests a role for thalamic inputs to striatum in

Cholinergic modulation of hippocampal network function

open access: yesFrontiers in Synaptic Neuroscience, 2013
Cholinergic septohippocampal projections from the medial septal area to the hippocampus are proposed to have important roles in cognition by modulating properties of the hippocampal network.

Biological Functions of Keratinocyte Cholinergic Receptors

open access: yesJournal of Investigative Dermatology Symposium Proceedings, 1997
Human epidermal keratinocytes possess cholinergic enzymes, which synthesize and degrade acetylcholine, and express both nicotinic and muscarinic classes of cholinergic receptors on their cell surfaces. These receptors bind acetylcholine and initiate cellular response.

Antinociceptive Activity of Methanolic Extract of Clinacanthus nutans Leaves: Possible Mechanisms of Action Involved

open access: yesPain Research and Management, 2018
Methanolic extract of Clinacanthus nutans Lindau leaves (MECN) has been proven to possess antinociceptive activity that works via the opioid and NO-dependent/cGMP-independent pathways.

Selectively driving cholinergic fibers optically in the thalamic reticular nucleus promotes sleep

open access: yeseLife, 2016
Cholinergic projections from the basal forebrain and brainstem are thought to play important roles in rapid eye movement (REM) sleep and arousal. Using transgenic mice in which channelrhdopsin-2 is selectively expressed in cholinergic neurons, we show ...

Muscarinic cholinergic receptors in rabbit retina

open access: yesJournal of Pharmacy and Pharmacology, 1985
Abstract Binding sites with high affinity and specificity for [3 H]-quinuclidinyl benzilate are present in rabbit retinal homogenates. Only one set of binding sites was detected with an apparent dissociation constant of 2.13 times 10−10 M and a density of 59.2 fmol mg−1 of protein.

Meta-Potentiation: Neuro-Astroglial Interactions Supporting Perceptual Consciousness [PDF]

open access: yes, 2007
Conscious perceptual processing involves the sequential activation of cortical networks at several brain locations, and the onset of oscillatory synchrony affecting the same neuronal population.

GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]

open access: yes, 2001
Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...
