Silver and zinc oxide nanomaterials are able to pass through an in vitro blood-brain barrier model in the form of both particles and dissolved ions.
While memories become less vibrant and detailed over time, the central gist of the memory is preserved.
The reactivation of learned material during slow oscillation/sleep spindle complexes, and the precision of SO-spindle coupling predicts how strong a memory will be reactivated in the brain.

Response to speech can be measured with EEG in unresponsive patients with TBI. The strength of the response can be used to accurately make a prognosis.
People make automatic and efficient decisions when learning to avoid others. When learning to avoid harming themselves, people make become more deliberative. The study also found people were more willing to repeat decisions that were previously harmful to themselves if they believed better results would occur in the future.
