by Don Arnold, The Conversation Credit: Pixabay/CC0 Public Domain All memory storage devices, from your brain to the RAM in your computer, store information by changing their physical qualities. Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons. Since...

by University of Nottingham Demethylation of RNA messages occurs during synaptic activation. Credit: The University of Nottingham Experts from the University of Nottingham have discovered that reversing the modification of molecular messages at synapses in the human brain, may contribute to reversible mental health conditions such as anxiety, and memory diseases such as dementia. The findings...

Researchers are one step closer to understanding the physiology of antidepressant action in the brain. They have confirmed that even when brain cells are not active, they trigger protein production that affects the function of cells and neural circuits.

by Weber Shandwick Worldwide Credit: Public Domain Alzheimer’s disease (AD), the most common type of dementia, causes the death of neurons and leads to the shrinking of the brain. Patients with AD will eventually experience gradual deterioration in memory, thinking, behavior, and the ability to perform everyday activities. Yet, scientists do not fully understand what causes...
New technique models brain cells in older patients more accurately than ever before Despite the prevalence of Alzheimer’s, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists at the Salk Institute have uncovered new insights into what goes awry during Alzheimer’s by growing neurons...

PARKINSON’S UK Wednesday 19 May 2021 – New research published today sheds important light on how the production of a key protein in the brain is controlled, which could pave the way for new treatments for a wide range of neurological conditions. In a study part-funded by Parkinson’s UK, researchers investigated a section of genetic material known...
by University of Oregon A neural stem cell and its progeny are seen under high-resolution imagery of their cell membranes in research at the University of Oregon. The stem cell is the large cell shown near the center with progeny from previous divisions, like grapes in a cluster, trailing to the left. The image is shown in false...
