Long-term memory isn’t stored in synapses, meaning it could be restored even when struck by Alzheimer’s

For a while, the general consensus was that long term memories are stored in synapses. A new  UCLA research topples this paradigm after experiments made on snails suggests that synapses aren’t that crucial storing memories as previously believed, but only facilitate the transfer of information someplace else, most likely in the nucleus of the neurons themselves – though this has yet

Storing info in computers frees up memory in the brain, helping us learn new things better

brain storage

Widespread use of computers is said to make people dumber or more prone to forgetfulness. It’s true, while we’re less inclined to memorize things such as poems or mathematical formulas, this doesn’t necessarily make it a bad thing. A study made by US psychologists found that when people save information on their computers or phones, this frees up cognitive resources

How the brain transforms bad experiences into long-lasting and unpleasant memories

Unpleasant memories are a lot easier to form than regular ones. Image: Silence of the Lambs.

Really bad experiences, like going through a particularly stressful or frighting situation, are a lot easier to remember than the things we do a day to day basis, or even those special pleasant experiences. That’s because we’re sort of evolutionary geared to remember those particularly nasty experiences so that we might avoid these in the future. A collaborative effort between New York

Steve Ramirez and Xu Liu are two neuroscientists who are at the very forefront of their field. Their work is focused on mapping the memory system, but also on how memory activation alters neural pathways, thus changing our mood. For instance, the two spoke recently during a TED talk about their most impressive experiment yet where they used blue light to

Fantasy and Reality – how does the brain tell the difference?

Some people, like history’s greatest artists or scientists, have a fantastic imagination that long transcends reality. Others have this line completely blurred and can’t make sense of what’s real or not. For most of us, however, fantasy and reality are clearly separated in our mental psyche. Now, a team of neuroscientists have explored the neural pathways that move information pertaining to

Anxiety can damage the brain and foster Alzheimer’s

Researchers at Baycrest Health Sciences’ Rotman Research Institute have found that patients diagnosed with mild cognitive impairment (MCI) who also show anxiety symptoms are at a much greater risk of developing Alzheimer’s. This was the first study of its kind that isolated anxiety in a longitudinal study covering people diagnosed with MCI, painting a clearer picture of how anxiety interferes with cognitive

Brain’s response to threat silenced when we are reminded of being loved and cared for

Something as small as seeing pictures of others being loved and cared for silences our brain’s response to threat, a new study has found. The amygdalae, listed in the Gray’s Anatomy textbook as the nucleus amygdalæ, are a group of nuclei in the brain involved in  the processing of memory, decision-making, and emotional reactions. The amygdala is also considered to be

Whether we’re assigned a learning task or choose to follow it, those subjects that interest us are always easier to comprehend, assimilate and remember over a long time. In this context, interest is actually another word for curiosity and a new research found that it is an important factor for effective learning. The team at University of California, Davis, found that

Automated tasks are still processed while you sleep

Despite an incredible body of work dedicated to researching what goes inside the brain while we sleep, consensus among neuroscientists suggests we’re just beginning to scratch the surface. For instance, we’ve yet to answer a fundamental question: why do we need sleep? We all agree that we needed it  – going without sleep for long periods of time can bring
