The newly discovered primate-specific interneuron is located in the striatum, a brain structure associated with cognition, reward, coordinated movement, Huntington's disease, and potentially schizophrenia.
Notes on verification
Confirmed by Broad Institute press release and peer-reviewed Nature 2020 paper (Krienen, Goldman et al.), with consistent follow-up literature. Note: 'primate-specific' status is being refined by newer 2024-2025 studies suggesting broader evolutionary distribution (e.g., bats), but the core claim as originally reported is well-supported.
