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

Almond (Amygdalus communis L.) Peptides Improve Scopolamine‐Induced Learning and Memory Impairment in Mice

open access: yesFood Safety and Health, EarlyView.
Figure Schematic showing the improvement of almond peptides on learning and memory impairment induced by scopolamine in mice. Almond peptides (APs) could improve the learning and memory in scopolamine‐induced mice by maintaining cholinergic system homeostasis and regulating Nrf2/Keap1 signaling pathway, via activating the Nrf2 transcription factor and ...

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.

Cognition in menopausal women

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Cognitive health in postmenopausal women is significantly affected by hormonal shifts, especially the drop in estrogen levels. This review explores the intricate relationship between menopause and cognitive functions across six domains: perception, attention, memory, language, executive functioning, and motor skills.

Artificial sensory and motor nervous systems enabled by bioinspired nanowire heterostructure synapse

open access: yesInfoMat, EarlyView.
A p‐i‐n heterostructured junction synaptic transistor was fabricated, composed of poly(3‐hexylthiophene‐2,5‐diyl) nanowire thin‐film/poly(methyl methacrylate)/ZnO nanowires (PZJ STs), which can emulate biological sensory and motor nervous systems.

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

open access: yesiNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

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.
