Researchers funded by the National Institutes of Health’s National Institute of Mental Health (NIMH) found that, in a mouse model, the ability to adapt to stress is driven by a distinctly different molecular mechanism than is the tendency to be overwhelmed by stress. The researchers mapped out the mechanisms – components of which also are present in the human brain – that govern both kinds of responses.

Researchers at the University at Buffalo, The State University of New York, have found that people with genetically lower dopamine, a neurotransmitter that helps make behaviors and substances more rewarding, find food to be more reinforcing than people without that genotype. In short, they are more motivated to eat and they eat more.

The study found that a molecule known as MMP-2 (which is induced by stem cells) has the ability to break down barriers on the outer surface of a damaged retina and allow healthy donor cells to integrate and wire themselves into remaining recipient tissue. The finding, reported in the current issue (April 25, 2007) of the Journal of Neuroscience, holds great promise not only for patients with retinal disease, but for those suffering from spinal cord injuries and neurodegenerative disorders such as ParkinsonÂ’s and AlzheimerÂ’s Diseases.

Their presence at the scene of damage is critical, but once their task is complete, it is just as critical that macrophages exit rapidly, ending the inflammatory process and making way for regrowth. In fact, the continued presence of macrophages could damage tissue, compromising repair.

In a forward movement, the objects flow by laterally, objects at the front increase in size and objects further away hardly change at all. At a higher level in the visual centre in the brain, there must be a computation of the visual information, so that animals can differentiate between their own movement and movement of their environment and are able to correct their course if necessary. It is important for the analysis of flow fields that the movement information from both eyes is merged so that the whole flow field can be assessed. In their current study, Karl Farrow, Jürgen Haag and Alexander Borst have for the first time proved the direct link between two nerve cells, one in each half of the brain, combining the movement signals from both the facetted eyes of a fly.

Inheriting two copies of this version more than doubled a child's risk of developing an autism spectrum disorder, scientists supported by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) National Institute on Child Health and Human Development (NICHD) have discovered. In a large sample totaling 1,231 cases, they traced the connection to a tiny variation in the part of the gene that turns it on and off. People with autism spectrum disorders were more likely than others to have inherited this version, which cuts gene expression by half, likely impairing development of parts of the brain implicated in the disorder, report Drs. Daniel Campbell, Pat Levitt, Vanderbilt Kennedy Center at Vanderbilt University, and colleagues, online during the week of the October 16, 2006 in the Proceedings of the National Academy of Sciences.

The findings suggest that certain forms of FTD, ALS and possibly other neurological diseases might share a common pathological process.

They said their findings in mice suggest that the protein, called Cathepsin B (CatB), is a key part of a protective mechanism that may fail in some forms of AD. Also, they said their findings suggest that drugs to enhance CatB activity could break down amyloid deposits, counteracting one of the central pathologies of AD.

Researchers have now discovered that the brain is able to prevent emotions from interfering with mental functioning by having a specific executive processing area of the cortex inhibit activity of the emotion-processing region.
