Researchers measured how brain waves travel in the prefrontal cortex during working memory tasks.

A newly developed artificial intelligence algorithm can accurately and reliably assess unconsciousness in patients under anesthesia based on brain activity.
Propofol, the commonly used anesthetic, alters and controls the dynamics of the brain's rhythms. The findings can help doctors better monitor patients under anesthesia with the aid of EEG.
New findings reveal how anesthesia-induced unconsciousness differs from normal sleep in relation to delta wave activity in the brain.
Study provides new insight into how brain waves control the flow of information through the cortex.
As novel visual patterns become familiar, stark changes occur in the visual cortex. Gamma rhythms give way to low-wave beta waves, and the neural activity switches from PV neurons in favor of inhibitory SOM neurons.
In visual working memory, the brain immediately transfers the memory of object shifts by re-encoding the memory among neurons in the opposite brain hemisphere.
Huntington's disease may progress to advanced stages as a result of degradation of the cells' health maintenance system than due to the increased disease pathology itself.
While some types of excitatory neurons respond to images and represent them in the visual cortex, the activity of two types of inhibitory interneurons combine in a circuit to reinforce visual stability and reliability.
