Briefings

A large international collaboration created the most detailed map of the human basal ganglia by profiling over 25 million cells. This work identified a new neuron type linked to schizophrenia and cell types associated with depression, bipolar disorder, and PTSD. Preliminary evidence suggests this precision could improve therapies for Parkinson's disease, where gene therapy targeting specific basal ganglia cells proved more effective and safer than blanket treatments.

Key points

• Scientists profiled more than 25 million cells to create the most detailed map of the human basal ganglia.
• A new neuron type was identified in the basal ganglia that appears to play a role in schizophrenia.

Context

The study was conducted by a massive scientific collaboration aiming to unravel human brain mysteries. The findings are significant because they provide preliminary evidence that precision-based therapies could improve treatments for Parkinson's disease, where current gene therapy approaches have shown superior safety and efficacy.

Limitations

The evidence is limited to preliminary findings from mouse models of Parkinson's disease. The study does not confirm the new neuron type's role in schizophrenia in humans, nor does it provide data on the specific cell types linked to depression, bipolar disorder, or PTSD in humans. The research remains in early stages with no definitive human clinical outcomes reported.
