Ever tried really hard to pinpoint your very first memory? Doctors say it has something to do with hippocampus overload.
Action games that use in-game GPS do not promote spatial reasoning and can lead to a gray matter decrease in the hippocampus.
In the hippocampus — which is weird, because we didn’t think it had anything to do with talking.
A groundbreaking research out of the Salk Institute suggests synapses are 10 times bigger in the hippocampus. Conversely, this means the memory capacity is 10 times larger than previously thought, given synapse size is directly related to memory. Moreover, the team found these synapses adjust in size constantly. Ever 20 minutes, synapses grow bigger or smaller adjusting themselves for optimal neural connectivity. The clues could prove paramount to developing artificial intelligence or computers that are more akin to the human brain: phenomenal computing power using minimal energy input.
Columbia University researchers have successfully identified the cellular network that allows mice to remember which environments are safe and which are dangerous. The study also looks into what happens when these neurons are tampered with, offering insight into how conditions such as PTDS, panic attacks and anxiety disorders can be treated.
It’s not just us humans that dream of a better future – rats do too. When rats rest, their brains imagine a favorable future such as a tasty treat, a new study by UCL researchers found.
Alcohol is generally regarded as unhealthy, with a myriad of long-term negative effects and even short term negative effects. But there are still many things we don’t understand about how alcohol interacts with out bodies. For example, a 2011 Texas research found that alcohol consumption helps some areas of our brain remember better, while a 2005 study showed that moderate
Researchers performed MRI scans on babies to see how their brains developed from birth to later stages. Their findings reveal the explosive growth of the human brain following birth: in just 90 days, the baby brain grows by 64% reaching half the adult size.
It’s estimated that some 8 million people in the United States suffer from post-traumatic stress disorder (PTSD), causing great angst, depression and poor social integration. There are numerous therapies and techniques designed to help patients recover and banish the specters that lurk in the deepest recesses of their minds, haunting them. A common psychotherapy is fighting fear with fear, by having
Meditation has been shown to have an impact on brain activity, decreasing beta waves and impacting each part differently. Activity in the frontal and parietal lobe slows down, while the flow of information to the thalamus is reduced. This can lead to positive side effects such as improved focus, better memory, and a reduction in anxiety. According to a new
Children are veritable knowledge sponges that can appropriate an intense amount of skills in a short amount of time. As we age, starting from the end of puberty, people seem to loose their ability of learning new skills as intense as children do. For instance, if a 30 year old French man decided to starting learning English, even if he
When the brain deems an experience meaningful enough, it will transfer that information from short-term storage, where typically information like where you put your car keys or the phone number of a person you just met gets stored temporarily, to your long-term memory, offering the possibility to be accessed at a later time. Neurologists claim this recording is made in
From a certain age onward, humans seem to process information at a slower pace – learning new things becomes more difficult, remembering where you put the car keys seems to give headaches, and it gets ever worse as we age even more. Neuroscientists at the University of Bristol studying dysfunctional neural communication in Alzheimer patients demonstrated that the number one likely culprit to
The latin phrase “mens sana in corpore sano” has been put to the test by researchers who wanted to study what kind of repercussions an unhealthy lifestyle has on the mind. What they found was a dramatic increase in brain damage and dementia cases among subjects who have experienced high blood pressure, diabetes, smoking and obesity in middle age. The study,
It’s pretty evident for anyone living in a big, crowded city what pollution looks like and to what degree our health is affected by it. Besides things like your lungs or skin, scientists relate in a new study published in Molecular Psychiatry, how they believe pollution can cause memory loss. To prove their point, they confined a group of lab
A team of neuro-scientists have managed to restore lost memories to rats by activating a part of their brains through an artificial memory chip – just like a sort of neuro-prosthesis. Further advances backed by this study might lead to the development of important leaps in long-term memory treatment, providing relief for Alzheimer or dementia patients. Researchers from Wake Forest
