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

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.

Cholinergic receptor labelling specific irreversible binding of bromoacetylcholine to cholinergic receptors at neuromuscular junctions

open access: yesEuropean Journal of Pharmacology, 1974
This study shows that (a) the slopes of dose-response curves of bromoacetylcholine (BrACh) and acetylcoline (ACh) were the same; (b) the dose-response curves of BrACh to contract superfused chick biventer cervicis and frog rectus abdominis muscles were shifted to the right by d-tubocurarine in a parallel fashio; and (c) the responses of BrACh were not ...

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 ...

Chronic Nicotine Selectively Enhances α4β2* Nicotinic Acetylcholine Receptors in the Nigrostriatal Dopamine Pathway [PDF]

open access: yes, 2009
These electrophysiological experiments, in slices and intact animals, study the effects of in vivo chronic exposure to nicotine on functional α4β2* nAChRs in the nigrostriatal dopaminergic (DA) pathway.

The key role of magnesium sulfate in the management of organophosphorus pesticide poisoning: a scoping literature review [PDF]

open access: yesClinical and Experimental Emergency Medicine
Organophosphorus agents are easily absorbed via respiratory, gastrointestinal, and dermal routes, and inhibit the acetylcholinesterase (AChE) enzyme, which is responsible for the majority of toxicity caused by organophosphates in the body.
