WebThe striatum, which serves as a gateway for the regulation of signals through the basal ganglia during the learning of actions and the selection of desirable actions, has the most-complex signaling architecture. WebJul 14, 2024 · Astrocytes and neurons coexist and interact in the CNS1,2. Given that many signaling and pathological events are protein-driven, identifying astrocyte and neuron proteomes is essential for elucidating the complex protein networks that dictate their respective contributions to physiology and disease. safe battery storage box

The ventral striatum contains both the nucleus accumbens (NAc), which is well established to contribute to motivated behavior, and the adjacent tubular striatum (TuS), which is poorly understood in this context. WebNov 21, 2024 · MSNs express either D1- or D2-type dopamine receptors and initiate the direct-pathway (dMSNs) or indirect pathways (iMSNs) of the basal ganglia, respectively. dMSNs have been shown to receive more inhibition than iMSNs from intrastriatal sources. safe bathtub pro bath chair lift
