Neurogenesis News and Research

RSS

Neurogenesis (birth of neurons) is the process by which neurons are generated. Most active during pre-natal development, neurogenesis is responsible for populating the growing brain.

Scientists have gained valuable new insight into the biology of aggressive, incurable brain tumors

A research study published in the March issue of Cancer Cell uses gene expression profiling to identify molecular profiles and signaling pathways associated with tumor aggressiveness and disease progression.

Brain memory modifies wiring during the female menstrual cycle

Researchers at Northwestern University and Columbia University have found that "wiring" in female rat brain memory area expands and retracts in relation to the amount of estrogen present during the estrous/menstrual cycle.

New understanding of how neurogenesis occurs

Scientists at the Salk Institute for Biological Studies have identified a crucial cellular signal that controls the fate of stem cells in the brains of adult mice.

Prozac helps learning and memory in people with Huntington's disease

People with Huntington's disease have progressive motor problems, cognitive deficits (dementia) and psychiatric symptoms (the most common is depression) that usually start to appear in mid-life. There is no cure and death usually results within 10 to 20 years of symptom onset, or faster in the childhood-onset form of the disease.

Release of the neurotransmitter GABA halts stem cell production in the brain

Release of the neurotransmitter GABA by adult neuronal precursor cells that develop into neurons limits stem cell proliferation, according to a study at Yale School of Medicine in the September issue of Nature Neuroscience.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

New roles for granulocyte colony-stimulating factor (G-CSF) in treating stroke

In a study appearing online on July 7 in advance of print publication of the August 1 issue of the Journal of Clinical Investigation, Armin Schneider and colleagues from Axaron Biosciences describe new roles for granulocyte colony-stimulating factor (G-CSF) in treating stroke and other central nervous system roles of this protein.

Scientists create new brain cells - in a dish

Regenerative medicine scientists at the University of Florida's McKnight Brain Institute have created a system in rodent models that for the first time duplicates neurogenesis - the process of generating new brain cells - in a dish.

After stopping drinking, the brain grows back - significant implications for treatment of alcoholism during recovery

University of North Carolina at Chapel Hill scientists have reported - for the first time - a burst in new brain cell development during abstinence from chronic alcohol consumption.

Molecular mechanisms behind XsalF's anterior specifying activity

Embryologists have long been interested in working out the means by which this regionalization is achieved, and for years the dominant theory has involved a two-step mechanism in which neural tissues are first induced lengthwise down the entire body axis, followed by a transformation step where a second signal specifies the posterior identities of the neural tissue

Having a good time can strengthen different centres in the brain and help it grow healthy brain cells

Dr Ian Reid, professor of mental health at the University of Aberdeen, told delegates that for many years psychiatrists believed that poor mental health was just caused by imbalances in various brain chemicals.
