Biggest Ever Map of Human Alzheimer’s Brain Published
An international team of researchers have compiled the largest dataset to date that details differences between healthy brains and those with Alzheimer's disease. The researchers have released the data online and is free to use. ... Read More...
New Way By Which the Brain Marks Time Identified
A new neuroimaging study helped researchers capture the processes by which the brain stores information related to when events happen. The findings could help further the understanding of age related dementia. ... Read More...
New Key Mechanism of Epileptic Seizures Revealed
According to a new mathematical model of seizures, only the conductivity of the AMPA receptors in neurons in the temporal lobe significantly change, leading to stronger excitation and synaptic signals.... Read More...
Navigating Our Thoughts: Fundamental Principles of Thinking
Researchers propose a new theory of human thinking, suggesting our brain's navigation system is key to thinking. This may explain why our knowledge seems to be organized in spatial fashion.... Read More...
How the Brain Combines Memories to Solve Problems
Using AI technology, researchers provide new insight into how the human brain connects individual episodic memories to help solve problems.... Read More...
How the Brain Experiences Time
Researchers have identified a network of cells in the entorhinal cortex that appear to play a key role into putting experience into a temporal context.... Read More...
The Link Between Obesity, Genetics and the Brain
A new study sheds light on the roles both genetics and neuroanatomy play in obesity. Researchers report those with higher BMI had reduced cognitive flexibility, reduced ability to delay gratification and worse verbal memory. Additionally, those with increased BMI have increased amygdala and left prefrontal cortex volume.... Read More...
Stimulating a Brain Pathway Reduces Depressive Behavior: Mouse Study
Stimulating the Ent circuit helped improve depressive behaviors in mouse models of major depressive disorder, researchers report.... Read More...
Can the Healthy Brain Offer Clues to Curing Alzheimer’s?
A new paper reports fully investigating the brain before the onset of dementia may herald clues for developing new treatments for Alzheimer's disease.... Read More...
Why Older People Might Lose Their Way
Researchers report the firing patterns of grid cells are less stable in older adults. This, they say, could be why older people have more problems with spatial navigation than younger people.... Read More...
