Complementary cognitive roles for D2-MSNs and D1-MSNs during interval timing.

The role of striatal pathways in cognitive processing is unclear. We studied dorsomedial striatal cognitive processing during interval timing, an elementary cognitive task that requires mice to estimate intervals of several seconds and involves working memory for temporal rules as well as attention to the passage of time. We harnessed optogenetic tagging to record from striatal D2-dopamine receptor-expressing medium spiny neurons (D2-MSNs) in the indirect pathway and from D1-dopamine receptor-expressing MSNs (D1-MSNs) in the direct pathway.

Limb disorders and slurred speech are common clinical symptoms associated with acute ischemic stroke. Although urinary incontinence is a known symptom in many cases of acute ischemic stroke, the simultaneous impairment of both bowel and bladder function is relatively rare. The occurrence of fecal and urinary incontinence as the primary clinical manifestation in minor acute ischemic stroke is especially uncommon.

Basal ganglia hemorrhage (BGH) is a prevalent site for intracerebral hemorrhage. Although neuroendoscopy (NE) surgery has emerged as a less invasive alternative to craniotomy (CT), the optimal surgical method remains debatable. This systematic review and meta-analysis aimed to compare the efficacy and safety of NE versus CT in the management of BGH.

Anxiety disorder, a prevalent mental health issue, is one of the leading causes of disability worldwide. Damage to the blood-brain barrier (BBB) is implicated in anxiety, but its regulatory mechanisms remain unclear. Herein, we show that adrenomedullin 2 (ADM2), a novel angiogenic growth factor, alleviates autistic and anxiety-like behaviors in mice.

Essential Tremor (ET) is characterized by action tremor often associated with resting tremor (rET). Although previous studies have identified widespread brain white matter (WM) alterations in ET patients, differences between ET and rET have been less explored. In this study we employed differential tractography to investigate WM microstructural alterations in these tremor disorders.
