中脑核(NAc)内的胆碱能中间神经元(ChIs)在动机性行为和相关疾病中起着重要作用。然而,虽然ChIs的激活已经在背侧纹状体中得到了很好的研究,但对它们如何参与NAc知之甚少。在这里,我们发现,腹侧海马(vHPC)和室旁核的丘脑(PVT)是主要的兴奋性输入,以ChIs在NAc内侧壳。当PVT激活ChI时,vHPC通过显著的前馈抑制引起放电的明显暂停。相反,背侧纹状体,这种抑制反映了强烈的连接到ChIs从当地的小白蛋白中间神经元。我们的研究结果揭示了不同的长程输入参与ChIs的机制,突出了纹状体局部连接的根本差异。Baimel等人研究了丘脑内侧核壳(NAcMS)中胆碱能中间神经元(ChI)的传入控制。输入从腹侧海马(vHPC)和室旁核的丘脑ChI放电有相反的影响。vHPC诱发的抑制反映了小清蛋白(PV+)中间神经元的激活,其强烈抑制NAcMS中的ChI。
Cholinergic interneurons (ChIs) in the nucleus accumbens (NAc) play a central role in motivated behaviors and associated disorders. However, while the activation of ChIs has been well studied in the dorsal striatum, little is known about how they are engaged in the NAc. Here, we find that the ventral hippocampus (vHPC) and the paraventricular nucleus of the thalamus (PVT) are the main excitatory inputs to ChIs in the NAc medial shell. While the PVT activates ChIs, the vHPC evokes a pronounced pause in firing through prominent feedforward inhibition. In contrast to the dorsal striatum, this inhibition reflects strong connections onto ChIs from local parvalbumin interneurons. Our results reveal the mechanisms by which different long-range inputs engage ChIs, highlighting fundamental differences in local connectivity across the striatum. Baimel et al. examine the afferent control of cholinergic interneurons (ChIs) in the nucleus accumbens medial shell (NAcMS). Inputs from the ventral hippocampus (vHPC) and paraventricular nucleus of the thalamus have opposing influence on ChI firing. vHPC-evoked inhibition reflects activation of parvalbumin (PV+) interneurons, which robustly inhibit ChIs in NAcMS.
