Sleep Is Vital to Remember People's Faces and Names Shows Recent Study

Photo by  Acharaporn Kamornboonyarush  from  Pexels According to recently published study by Northwestern University, when people's memories of freshly taught face-name connections were reactivated while they were sleeping, researchers discovered that their name recall improved dramatically. Uninterrupted deep sleep was crucial to this progress. Nathan Whitmore, a PhD candidate in the Interdepartmental Neuroscience Program at Northwestern said, “It’s a new and exciting finding about sleep, because it tells us that the way information is reactivated during sleep to improve memory storage is linked with high-quality sleep .” Memory reactivation did not benefit and may even be harmful to study participants with EEG data (a recording of electrical activity in the brain picked up by electrodes on the scalp) that indicated interrupted sleep. The reactivation resulted in a relative improvement of a little over 1.5 more names recalled in those who slept uninterrupted throughout the specif

An ant colony has memories that its individual members don’t have

Like a brain, an ant colony operates without central control. Each is a set of interacting individuals, either neurons or ants, using simple chemical interactions that in the aggregate generate their behaviour. People use their brains to remember. Can ant colonies do that? This question leads to another question: what is memory? For people, memory is the capacity to recall something that happened in the past. We also ask computers to reproduce past actions – the blending of the idea of the computer as brain and brain as computer has led us to take ‘memory’ to mean something like the information stored on a hard drive. We know that our memory relies on changes in how much a set of linked neurons stimulate each other; that it is reinforced somehow during sleep; and that recent and long-term memory involve different circuits of connected neurons. But there is much we still don’t know about how those neural events come together, whether there are stored representations that we use to t

Elephants- Nature's masterpiece

Apart from being big memory hoarders, elephants display a whole lot of emotion, we are just starting to understand. These gentle giants are known to have big brains as well as big hearts (metaphorically as well). This fun TED-Ed to remind us how magnificent the elephant truly is.
