Experience affects new neuron survival in adult brain; study sheds light on learning, memory
03-22-2007 · EurekAlert!Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults.

- Adult brain cells rediscover their inner child
05-23-2007 · EurekAlert!
Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child. The study, appearing this week in Neuron, suggests that new adult nerves have a deeper role than simply replacing dead ones.

- HIV is a 'double hit' to the brain
08-15-2007 · EurekAlert!
New evidence reported in the August issue of Cell Stem Cell, a publication of Cell Press, offers a novel perspective on how the HIV/AIDS virus leads to learning and memory deficits, a condition known as HIV-associated dementia. A protein found on the surface of the virus not only kills some mature brain cells, as earlier studies had shown, but it also prevents the birth of new brain cells by crippling "adult neural progenitors," the new study finds.

- Research explains how lead exposure produces learning deficits
04-03-2007 · EurekAlert!
Exposure to levels of lead that are similar to those measured in lead-intoxicated children reduces the birth and survival of new neurons (neurogenesis) in the brain. A study of young adult rats by researchers from the Johns Hopkins Bloomberg School of Public Health provides evidence that explains exactly how exposure to lead during brain development produces learning deficits.

- Tears reveal some of their deepest secrets to researchers
01-19-2007 · EurekAlert!
It's no secret why we shed tears. But exactly what our tears are made of has remained a mystery to scientists. A new study sheds some light on the complex design of tears. What we think of as tears, scientists call tear film, which is made up of three distinct, microscopic layers.

- Brain structure changes years before memory loss begins
04-16-2007 · EurekAlert!
People who develop dementia or Alzheimer's disease experience brain structure changes years before any signs of memory loss begin, according to a study published in the April 17, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology. Researchers say these findings may help identify people at risk of developing mild cognitive impairment, which leads to Alzheimer's disease.

- New adult brain cells may be central to lifelong learning
05-23-2007 · EurekAlert!
The steady formation of new brain cells in adults may represent more than merely a patching up of aging brains, a new study has shown. The new adult brain cells may serve to give the adult brain the same kind of learning ability that young brains have while still allowing the existing, mature circuitry to maintain stability.
