Here's a short selection of our favorite neuroscience stories from the last week!
1. “Do-Re-Mi” may be fundamental to western music, but not to the human brain, suggests a fascinating new study that has assessed the ability of an isolated community of people living in the Bolivian rainforest to recognize musical notes arranged in the western octave structure.
2. New research suggests that positive childhood experiences are essential for our long-term health — especially for those who experience significant adversity as a child.
3. It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes.
4. Findings suggest that two short peptides, or strings of amino acids, when injected into mice with Alzheimer's disease daily for five weeks, significantly improved the mice's memory. The treatment also reduced some of the harmful physical changes in the brain that are associated with the disease.

5. A wearable head device that blasts the brain with electromagnetic waves has been shown to enhance cognitive performance in a very small study of patients with Alzheimer's disease. Results demonstrate that the TEMT device was safe in all eight participating patients with mild to moderate AD.
