UQ discovers emotive protein
July 18 – University of Queensland researchers have identified a protein involved in memory and other emotive functions. The researchers identified the protein within a section of the brain responsible for mediating emotions, the amygdala. Emotive based neurological disorders are thought to stem from changes in connective strength between cells within the amygdala. The protein itself was found to play a role in regulating information processing, and when blocked, increased strength between these cells. It is thought that the discovery may lead to the development of treatment strategies for numerous mental disorders such as post traumatic stress, anxiety and depression.

Protein regenerates brain and spinal cord
July 25 - Researchers at the University of Helsinki have discovered a KDI tripeptide that inhibits glutamate and has been shown to prevent permanent nerve cell death. When injected directly into the damaged area, KDI has been shown to increase synaptic function and neurite outgrowth between damaged neurones but does not regenerate new neurones. The study does not represent a cure but it is hoped to contribute to methods of reducing disease progression when incorporated into an effective drug.
