first thing to share here!
excited to share lab’s first study in Parkinson’s disease revealing the prodromal vulnerability and function of the dopamine neuron subtype defined by Anxa1 expression - a specialized system controlling procedural motor learning

(first post in this platform) happy to share our new paper on visual-based center-surround interactions in the superior colliculus, showcasing a general approach to dissect local circuit computations. @NeuroAlc
Can there be a “little brain” in the heart?
This is one of the “out of the box” project that we performed as KizilLab and
AmpatzisLab. Huge thanks to Andrea, Kostas and Caghan 🤘🏻

Progressive degeneration of dopamine neurons (DANs) defines Parkinson's disease (PD). However, the identity and function of the most vulnerable DAN populations in prodromal PD remain undefined. Here, ...

The two novel pathways control dopamine release in opposing ways and may link motivation and mood to action, a new study shows.
We demonstrate here that astrocytes in the striatum interact with striatal dopamine in bidirectional signaling with dopamine release actively driving surges in astrocytic Ca++, which in turn modulate ...

Lazaridis et al. delineate a previously unrecognized pair of striosomal direct D1 and indirect D2 circuits that target substantia nigra dopamine-containing neurons, controllers of mood, action, and reinforcement learning. These striosomal circuits have effects opposing those of the canonical D1-direct/D2-indirect pathways, likely modulating them.
Although the heart has its own nervous system, its organization and functionality remain largely unknown. Here, the authors reveal the molecular, chemical, and functional diversity of neurons within t...
