REM Sleep Disengagement of β Oscillations Permits Rapid Dream Movements in Parkinsonism

The paper shows that REM sleep suppresses β oscillations in Parkinsonism, allowing rapid movements despite motor impairments during wakefulness.

Basal ganglia-independent thalamic bursts do not wake cortex during sleep

The paper investigates thalamic bursts during sleep and finds they do not wake the cortex, suggesting a modulatory role of the basal ganglia-thalamus interaction.

Non-linear input-output relationships in the subthalamic nucleus of Parkinson's patients

The paper examines non-linear input-output relationships in the subthalamic nucleus of Parkinson's patients by analyzing local field potentials and spiking activity.

Basal Ganglia Stimulation Ameliorates Schizophrenia Exploration Anomalies

This study shows that GPe stimulation restores exploration-exploitation balance disrupted by PCP in NHPs, suggesting potential therapeutic benefits for schizophrenia.

Dichotomous Activity and Function of Neurons with Low- and High-Frequency Discharge in the External Globus Pallidus of Non-Human Primates

This study examines the functional differences between low- and high-frequency discharge neurons in the external globus pallidus of non-human primates during a conditioning task, revealing distinct firing patterns and roles.

Entrainment to sleep spindles reflects dissociable patterns of connectivity between cortex and basal ganglia

This study investigates how sleep spindles coordinate neural activity between the cortex and basal ganglia in non-human primates, revealing distinct patterns of connectivity in different BG regions.

Non-uniform distribution of dendritic nonlinearities differentially engages thalamostriatal and corticostriatal inputs onto cholinergic interneurons

The paper investigates how non-uniform distribution of dendritic currents in cholinergic interneurons differentially processes thalamostriatal and corticostriatal inputs.

Spontaneous pauses in firing of external pallidum neurons are associated with exploratory behavior

The paper links spontaneous firing pauses in external pallidum neurons to exploratory behavior through increased saccade rate and pupil dilation.

Toward asleep DBS: Cortico basal-ganglia neural activity during interleaved propofol/ketamine sedation mimics NREM/REM sleep activity

The paper characterizes cortico-basal ganglia neural activity under different sedation states and compares them to sleep states to inform asleep DBS.

Frequency matters: Up- and Down-Regulation of Dopamine Tone Induces Similar Frequency Shifts in Cortico-Basal Ganglia Beta Oscillations

The paper shows that dopamine levels affect beta oscillation frequency, not power or coherence, in cortico-basal ganglia networks of NHPs and PD patients.

Phase-specific microstimulation in brain-machine interface setting differentially modulates beta oscillations and affects behavior

This study uses a hybrid platform to explore how phase-specific microstimulation modulates beta oscillations and affects behavior in monkeys.

Neuronal activity and learning in local cortical networks are modulated by the action-perception state

The paper shows that neuronal patterns in motor cortex change during brain-machine interface learning to align with the current action-perception state, with pre-learning activity predicting these changes.

Movement context modulates neuronal activity in motor and limbic-associative domains of the human subthalamic nucleus

The paper investigates how movement context affects neuronal activity in different subthalamic nucleus domains in Parkinson's patients during movement tasks.
