Patterns of coordinated activity in the basal ganglia predict how much force we will use to grip objects, suggesting that individuals with paralysis may ultimately be able to use these signals to control graded responses in robotic devices.
Impaired GABAergic and glutamatergic synaptic function and loss of interneurons in the amygdala, hippocampus, and cerebellum cause characteristic disease symptoms in a mouse model juvenile neuronal ceroid lipofuscinosis.
The spiking activity of the subthalamic nucleus, rather than the activity of striatal projection neurons, orchestrates basal ganglia downstream activity and output commands in health and Parkinson’s disease.
Motor fatigability is associated with a decrease in inhibition throughout the motor network, suggesting that selective inhibitory control is a key mechanism to maintain motor efficiency during repetitive movements.
Optical recordings reveal previously unknown neuromodulator dynamics in the striatum during animal movements that suggest a new interpretation of the underpinnings of bradykinetic movements exhibited in Parkinson's Disease patients.
