Web1 day ago · Abstract. Self-grooming is an innate, naturalistic behavior found in a wide variety of organisms. The control of rodent grooming has been shown to be mediated by the dorsolateral striatum through lesion studies and in-vivo extracellular recordings. Yet, it is unclear how populations of neurons in the striatum encode grooming. WebMore recent interest in the striatum has also focused on the actions of opiates and endogenous opiate peptides (enkephalins). Indeed the striatum contains significant amounts of enkephalin and an enkephalin-containing striatopallidal fiber system has been described ( Cuello & Paxinos, 1978 ). Moreover, the highest degree of opiate receptor ...

Striatal outputs from both the dorsal and ventral components are primarily composed of medium spiny neurons (MSNs), a type of projection neuron, which have two primary phenotypes: "indirect" MSNs that express D2-like receptors and "direct" MSNs that express D1-like receptors.

WebApr 13, 2024 · Exposure to heavy metals, including cadmium (Cd), can induce neurotoxicity and cell death. Cd is abundant in the environment and accumulates in the striatum, the primary brain region selectively affected by Huntington’s disease (HD).
