A small study shows that stress makes it more likely for learning to use more complicated and subconscious processes that involve brain regions involved in habit and procedural learning.

We know that stress has a complicated relationship with learning, but in general its effect is negative, and part of that is due to stress producing anxious thoughts that clog up

A pilot study supports the value of brief cognitive therapy for victims of traumatic events, when delivered as soon as possible after the event. The benefit appears greatest for sexual assault victims.

A new study has found that, when delivered quickly, a modified form of prolonged exposure therapy reduces post-traumatic stress reactions and depression.

A small study extends the evidence that even mild concussions can cause brain damage, with the finding that frequent heading of the ball in soccer can cause similar damage.

American football has been in the news a lot in recent years, as evidence has accumulated as to the brain damage incurred by professional footballers. But American football is a high-impact sport. Soccer is quite different.

Effective patterns of neural activity replayed via an artificial device inserted in the hippocampus restores lost learning capability and even improves learning in normal rats.

In the experiment, rats learned which lever to press to receive water, where the correct lever depended on which lever they had pressed previously (the levers were retractable; there was a variable delay between the first and second presentation of the levers).

In a small study, a sleepless night after trauma prevents the development of PTSD symptoms.

Given all the research showing the importance of sleep for consolidating memories, it should come as no great surprise that the reverse is also true: depriving yourself of sleep could help you forget experiences you would prefer not to remember.

A new drug is successful in preventing PTSD in mice if delivered within 5 hours of the trauma.

A mouse study has revealed the brain becomes overly stimulated after a traumatic event causes an ongoing, frenzied interaction between two brain

Playing Tetris shortly after a traumatic event reduced flashbacks, but playing a word-based quiz increased the number of flashbacks.

Following a study showing that playing Tetris after traumatic events could reduce memory flashbacks in healthy volunteers, two experiments have found playing Tetris after viewing traumatic images significantly reduced flashbacks while playing Pub Quiz Machine 2008 (a word-based quiz game) increa

Recent rodent studies confirm attention and learning is more difficult for women when estrogen is high, but estrogen therapy can help menopausal women — if given during a critical window.

Recent rodent studies add to our understanding of how estrogen affects learning and memory.

It seems that prosopagnosia can be, along with perfect pitch and eidetic memory, an example of what happens when your brain can’t abstract the core concept.

‘Face-blindness’ — prosopagnosia — is a condition I find fascinating, perhaps because I myself have a touch of it (it’s now recognized that this condition represents the end of a continuum rather than being an either/or proposition).

Watching another person do something can leave you with the memory of having done it yourself.

I’m not at all sure why the researcher says they were “stunned” by these findings, since it doesn’t surprise me in the least, but a series of experiments into the role of imagination in creating false memories has revealed that people who had watched a video of someone else doing a simple action
