The hippocampus is a major component of the brains of humans and other vertebrates. It belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is a part of the cerebral cortex; and in primates it is located in the medial temporal lobe, underneath the cortical surface. It contains two main interlocking parts: Ammon's horn and the dentate gyrus.
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
