Meditation involves attentional regulation and may lead to increased activity in brain regions associated with attention such as dorsal lateral prefrontal cortex (DLPFC) and anterior cingulate cortex (ACC). Using functional magnetic resonance imaging, we examined whether DLPFC and ACC were activated during meditation. Subjects who meditate were recruited and scanned…
Binaural beats happen when two slightly different tones are played to each ear and you hear a third, pulsing tone at the difference between them. This review looked at 14 studies that measured brain activity after binaural-beat sounds. The results were mixed: some studies found brain activity that matched the…
This randomized, double-blind, placebo-controlled crossover study gave subanesthetic S‑ketamine to 24 healthy young people while recording fMRI and EEG at rest. After ketamine, fMRI showed less connectivity in the medial prefrontal cortex and more connectivity in left and right intraparietal (parietal) areas of the default mode network. EEG showed more…
The authors made a score that measures how male-typical a person’s subcortical brain shape is. They trained this score on 2,153 people and then measured it in 1,060 people with autism and 1,166 neurotypical controls. People with autism had a small, higher average “brain maleness” score (d = 0.20), and…
