Area of Science:

Neuroscience
Systems Neuroscience
Computational Neuroscience

Background:

Beta-band oscillations (20-30 Hz) are implicated in sensorimotor functions.
Understanding their precise role requires advanced experimental techniques.

Purpose of the Study:

To investigate the functional role of Beta-band oscillations in sensorimotor behavior.
To explore the effects of volitionally controlling and perturbing these oscillations.

Main Methods:

Developed a hybrid platform combining neural operant conditioning and phase-specific intracortical microstimulation (ICMS).
Trained monkeys with motor cortex implants to enhance local field potential (LFP) Beta-band activity via a brain-machine interface (BMI).
Applied phase-specific ICMS to modulate oscillation power and phase.

Main Results:

BMI training significantly increased Beta-band oscillations in LFP and single-unit activity.
Pre-movement Beta power was negatively correlated with task performance.
Phase-specific ICMS altered oscillation states and induced phase-dependent effects on reaction times and success rates.

Conclusions:

Beta-band oscillations are dynamically modulated during sensorimotor tasks and influence performance.
Phase-specific ICMS can manipulate neural network states and behavior.
Findings advance understanding of cortical oscillations and inform development of clinical interventions for neurological disorders.
