What, if, and when to move: basal ganglia circuits and self-paced action initiation

A Klaus, J Alves da Silva… - Annual review of …, 2019 - annualreviews.org
Deciding what to do and when to move is vital to our survival. Clinical and fundamental
studies have identified basal ganglia circuits as critical for this process. The main input …

Basal ganglia circuits for action specification

J Park, LT Coddington… - Annual review of …, 2020 - annualreviews.org
Behavior is readily classified into patterns of movements with inferred common goals—
actions. Goals may be discrete; movements are continuous. Through the careful study of …

Striatal activity topographically reflects cortical activity

AJ Peters, JMJ Fabre, NA Steinmetz, KD Harris… - Nature, 2021 - nature.com

[PDF][PDF] The dorsal striatum energizes motor routines

MT Jurado-Parras, M Safaie, S Sarno, J Louis… - Current Biology, 2020 - cell.com
The dorsal striatum (dS) has been implicated in storing procedural memories and controlling
movement kinematics. Since procedural memories are expressed through movements, the …

Dissociating the contributions of sensorimotor striatum to automatic and visually guided motor sequences

KGC Mizes, J Lindsey, GS Escola, BP Ölveczky - Nature Neuroscience, 2023 - nature.com
The ability to sequence movements in response to new task demands enables rich and
adaptive behavior. However, such flexibility is computationally costly and can result in …

Continuous representations of speed by striatal medium spiny neurons

WC Fobbs, S Bariselli, JA Licholai… - Journal of …, 2020 - Soc Neuroscience
The striatum is critical for controlling motor output. However, it remains unclear how striatal
output neurons encode and facilitate movement. A prominent theory suggests that striatal …

T Macpherson, M Matsumoto, H Gomi, J Morimoto… - Neural Networks, 2021 - Elsevier
Our brain can be recognized as a network of largely hierarchically organized neural circuits
that operate to control specific functions, but when acting in parallel, enable the performance …

[HTML][HTML] A GABAergic and peptidergic sleep neuron as a locomotion stop neuron with compartmentalized Ca2+ dynamics

W Steuer Costa, P Van der Auwera, C Glock… - Nature …, 2019 - nature.com
