Severe and enduring eating disorders carry the highest mortality rate of all psychiatric illnesses, especially when combined with treatment-resistant depression. Four patients with both conditions received repeated ketamine treatments over 12 or more months. Depression improved, but eating disorder symptoms changed only modestly.
Meditators outperformed non-meditators in brain-computer interface (BCI) cursor control tasks using motor imagery. Experienced meditators showed better performance in both 1-dimensional and 2-dimensional tasks, and fewer meditators were unable to generate decodable EEG signals. Meditators also had higher sensorimotor rhythm (SMR) predictor values and were better able to produce decodable EEG signals for SMR-based BCI control, suggesting meditation training may improve BCI performance.
Experienced meditators outperformed meditation-naïve subjects in one-dimensional and two-dimensional cursor control tasks using a sensorimotor rhythm-based brain–computer interface. Fewer meditators were classified as BCI inefficient. Meditators also showed a higher resting SMR predictor, more stable resting mu rhythm, and larger control signal contrast during the task, suggesting that meditation training may enhance BCI performance.
