Callahan J, Morales J, Atherton J, Wang D, Kostic S, Bevan M
Cell Rep
. 2024 Jul;
43(8):114495.
PMID: 39068661
The subthalamic nucleus (STN) is traditionally thought to restrict movement. Lesion or prolonged STN inhibition increases movement vigor and propensity, while optogenetic excitation has opposing effects. However, STN neurons often...

J Neurosci
. 2022 Jan;
42(10):2080-2102.
PMID: 35058372
The debilitating psychomotor symptoms of Huntington's disease (HD) are linked partly to degeneration of the basal ganglia indirect pathway. At early symptomatic stages, before major cell loss, indirect pathway neurons...

Kovaleski R, Callahan J, Chazalon M, Wokosin D, Baufreton J, Bevan M
J Physiol
. 2020 Mar;
598(10):1897-1927.
PMID: 32112413
Key Points: Reciprocally connected GABAergic external globus pallidus (GPe) and glutamatergic subthalamic nucleus (STN) neurons form a key network within the basal ganglia. In Parkinson's disease and its models, abnormal...

J Physiol
. 2015 May;
593(16):3727-38.
PMID: 25952461
Key Points: Neural synchrony between the subthalamic nucleus (STN) and cortex is critical for proper information processing in basal ganglia circuits. Using in vivo extracellular recordings in urethane-anaesthetized mice, we...

Neurobiol Dis
. 2015 Mar;
78:88-99.
PMID: 25772440
Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder that results in motor, cognitive and psychiatric abnormalities. Dysfunction in neuronal processing between the cortex and the basal ganglia is fundamental...

Exp Neurol
. 2011 Aug;
232(2):119-25.
PMID: 21864528
Huntington's disease (HD) is a genetic neurodegenerative disorder that is characterized by the progressive onset of cognitive, psychiatric, and motor symptoms. In parallel, the neuropathology of HD is characterized by...

PMID: 21811446
Huntington's disease (HD) is characterized by numerous alterations within the corticostriatal circuitry. The striatum is innervated by a dense array of dopaminergic (DA) terminals and these DA synapses are critical...
