Claim 1activity patternsupports2025Source 1DOI PubMed

Single SNr neurons exhibit movement-specific firing pauses as well as increases, each associated with precise and different forelimb movements.

Claim 2mechanistic functionsupports2025Source 1DOI PubMed

Dynamic firing-rate changes in basal ganglia output neurons functionally release and suppress movement through downstream brainstem targets.

Claim 3model proposalsupports2025Source 1DOI PubMed

Basal ganglia output neurons provide granular and bidirectional movement-specific signals that release and suppress motor programs in downstream circuits.

Claim 4neural representationsupports2025Source 1DOI PubMed

Mouse SNr basal ganglia output neurons represent complex forelimb movements with highly granular and dynamic spiking changes that tile task execution at the population level.
