Second Type of Stem Cell Discovered in the Mouse Brain
In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. Researchers recently discovered a second stem cell population in the mouse brain. This new type of stem cell, and not the one previously known, is primarily involved in the production of new neurons in the olfactory bulb of adult mice.

X-Chromosome Linked Protein Could Explain Higher Alzheimer's Rates in Women
Researchers have discovered that the female brain shows higher expression of an enzyme that results in greater accumulation of tau, the protein responsible for the formation of toxic protein clumps in the brains of Alzheimer’s disease patients.

Genes Behind Increased Chance of Autism, ADHD (or Both) Identified
There is a large degree of overlap between the genetic causes of autism and ADHD. Now, researchers from Aarhus University have found gene variants, which increase the risk of developing only one of the diagnoses and not the other.

Neurodegenerative Disease Fueled by "Leaky" Mutated Protein
The mechanism by which a mutated protein drives a type of neurodegenerative disease – characterized by the degradation of neurons – has been identified.

Many Alzheimer's Brain Changes Have Nothing To Do With Neurons
According to research, many of the changes in Alzheimer’s disease occur in brain cells other than neurons.
