Quantifying harmony between direct and indirect pathways in the basal ganglia: healthy and Parkinsonian states

SY Kim, W Lim - Cognitive Neurodynamics, 2024 - Springer
The basal ganglia (BG) show a variety of functions for motor and cognition. There are two
competitive pathways in the BG; direct pathway (DP) which facilitates movement and indirect …

Break-up and recovery of harmony between direct and indirect pathways in the basal ganglia: Huntington's disease and treatment

SY Kim, W Lim - Cognitive Neurodynamics, 2024 - Springer
