Manipulating specific brain waves in sleep shifts balance between learning or forgetting a new skill

Distinct patterns of electrical activity in the sleeping brain may influence whether we remember or forget what we learned the previous day, according to a new study. The scientists were able to influence how well rats learned a new skill by tweaking these brainwaves while animals slept, suggesting potential future applications in boosting human memory or forgetting traumatic experiences, the researchers say.

Pesticides likely caused 'Havana syndrome' that affected Cuba-based diplomats

The study details the nature of the injury, specifies the brain regions involved, including the blood-brain barrier and suggests a possible cause in the form of 'cholinesterase inhibitors,' with 'organophosphorus insecticides' being a likely source. Cholinesterase (ChE) is one of the key enzymes required for the proper functioning of the nervous systems of humans, invertebrates and insects.
