Cholinergic interneurons striatum
WebJan 10, 2007 · We investigated this issue in the striatum using paired recordings from cholinergic interneurons and projection neurons. Glutamatergic EPSCs were evoked in projection neurons and cholinergic interneurons by stimulation of afferent fibers in the cortex and the striatum, respectively. WebAug 31, 2016 · Over the last decade, striatal cholinergic interneurons (ChIs) have reemerged as key actors in the pathophysiology of basal-ganglia-related movement disorders. However, the mechanisms involved are still unclear. In this study, we address the role of ChI activity in the expression of parkinsonian-like motor deficits in a unilateral …

WebAug 13, 2024 · The striatum is a central brain structure important for the initiation and coordination of motor functions, sensory processing, and reward (1–3).The striatal neuronal composition is dominated by a vast majority (∼95%) of projection neurons, the so called medium spiny neurons (MSNs), and a small yet diverse population of interneurons. WebJan 1, 2016 · These interneurons are hyperpolarized (resting membrane potential ~−80 mV) and display no spontaneous activity at rest. In a seminal study, of 11 neurons with these electrophysiological characteristics, 10 were immunopositive for PV and termed FSIs due to their suprathreshold electrophysiological properties ( Kawaguchi, 1993 ).
WebApr 1, 2015 · Cholinergic interneurons consist of approximately 2% of total neurons in the dorsal striatum [ 6 ]. Although they are sparsely distributed, studies have provided a growing body of evidence that cholinergic interneurons are involved in the important functions of associative learning, reward processing, and motor control [ 11 ]. Web2 days ago · Interneurons were distinguished and excluded from data analysis based on their signature electrophysiological properties, i.e., relatively depolarized resting membrane potentials (approximately ...
WebMay 12, 2015 · Conversely, neurochemically specific ablation of cholinergic interneurons did not significantly change habitual responding or response substitution. Thus, activation –but not ablation –of cholinergic interneurons in the dorsolateral striatum modulates expression of a new habit when an old habit is replaced by a new one.
