High fat diet impairs new neuron creation in female mice
Female mice exposed to a high-fat diet have limited hippocampal neurogenesis. The findings may explain why women are at higher risk of developing dementia than men.... Read More...

How chronic stress causes brain damage
Chronic stress causes autophagy in adult hippocampal neural stem cells. This results in a decline of hippocampal neurogenesis. Cognitive deficits and mood disorders that arise as a result of chronic stress are a result of autophagic death of hippocampal neural stem cells.... Read More...
New neurons form in the brain into tenth decade of life, even in people with Alzheimer’s
Hippocampal neurogenesis continues to occur well into old age, and in those with Alzheimer's disease. Researchers found evidence of neurogenesis in people up to the age of 99. While neurogenesis continues to occur in those with Alzheimer's disease, it is significantly reduced compared to those who have normal cognitive function.... Read More...
Lessons Learned From the Adult Neurogenesis Debate
A new paper looks at the controversies surrounding adult neurogenesis.... Read More...
Stroke Produces Dysfunctional Brain Cells
Researchers report that following a stroke, the production of new neurons in the hippocampus fail to develop correctly. However, intervening in the production of these neurons could help mitigate memory problems experienced by those who suffer a stroke.... Read More...
Exercise Generates New Neurons and Improves Cognition in Alzheimer’s: Mouse Study
Researchers report exercise can promote adult hippocampal neurogenesis and improve cognition in mouse models of Alzheimer's disease. The study identifies ways to mimic the beneficial effects of experience through pharmacological and gene therapy. ... Read More...
Alzheimer’s Risk Gene Impairs Neurogenesis: Mouse Study
A new mouse study finds APOE genes, commonly associated with Alzheimer's disease, impairs the development of new neurons in areas of the brain associated with memory.... Read More...
How Do Adult Brain Circuits Regulate New Neuron Production?
UNC researchers have identified a brain circuit that runs from near the front of the brain to the hippocampus that helps to control neurogenesis.... Read More...
Natural Pigment Astaxanthin Promotes Hippocampal Neurogenesis
A natural red pigment that is abundant in salmon and crustaceans appears to promote hippocampal neurogenesis, a new study reports.... Read More...
The Power of Positive Memory Recall
According to new research, stress induced depression may be overcome by inducing neurons which were activated during previous positive experiences.... Read More...
Signal Found to Enhance Survival of New Brain Cells
Researchers discover how parvalbumin-expressing interneurons, which usually limits stem cell activity, can also encourage the survival of the stem cells' progeny. ... Read More...
