27 de mar. de 2024 · When a long-term memory forms, some brain cells experience a rush of electrical activity so strong that it snaps their DNA. Then, an inflammatory response kicks in, repairing this damage and ...

26 de jul. de 2023 · Memory is an essential cognitive function that permits individuals to acquire, retain, and recover data that defines a person’s identity (Zlotnik and Vansintjan, 2019). Memory is a multifaceted cognitive process that involves different stages: encoding, consolidation, recovery, and reconsolidation.

Different types of memory are created and stored in varying ways, and in various areas of the brain. Researchers are still pinpointing the details, but they know that autobiographical memories — those of events experienced personally — begin to take lasting form in a part of the brain called the hippocampus, in the hours and days that follow the ev...
A few years later, Hardt found something similar in rats. He was investigating what happens at the synapses of neurons that are involved in long-term memory storage. Researchers know that memories are encoded in the mammalian brain when the strength of the connection between neurons increases. That connection strength is determined by the amount of...
Researchers think that the human brain might operate in a similar way. “Our ability to generalize new experiences is, at least in part, due to the fact that our brains engage in controlled forgetting,” says Blake Richards, who studies neural circuits and machine learning at the University of Toronto Scarborough. Richards suggests that the brain’s a...
By better understanding how we forget, through the lenses of both biology and cognitive psychology, Anderson and other researchers might be edging nearer to improving treatments for anxiety, PTSD and even Alzheimer’s disease. Anderson’s work to measure GABA levels in the brain might indicate a mechanism that underpins the effectiveness of benzodiaz...

7 de nov. de 2019 · Recent developments in science and technology point to the need to unify, and extend, the definition of memory. On the one hand, molecular neurobiology has shown that memory is largely a neuro-chemical process, which includes conditioning and any form of stored experience.

24 de jun. de 2019 · Exposure to natural environments has been shown to improve performance on working memory, cognitive-flexibility, and attentional-control tasks. These results come from studies conducted using a variety of simulated environments (e.g., images, sounds, virtual reality) as well as real-world environmental exposure ( Schertz et al., 2018 ...

16 de dez. de 2002 · Rather, we found that superior memorizers used a spatial learning strategy, engaging brain regions such as the hippocampus that are critical for memory and for spatial memory in particular.
12 de out. de 2023 · The concept of collective memory has been the subject of numerous theoretical debates and a wide range of empirical studies. Its suggestive power has inspired pioneering work on memory in the social sciences and, more recently, a social turn in the fields of psychology and cognitive neuroscience.
