New research suggests that the brain creates at least three copies of each memory. This also includes those encoded by early-formed neurons, which appear purple in a microscope cross-section of a mouse hippocampus. (Image credit: Biozentrum, University of Basel)

Neurologists have identified the origins of creativity in the brain

Creativity is a unique brain function. Local damage to the brain as a result of a stroke can lead to changes in creative ability—both positive and negative. This discovery suggests that the neurological basis of creativity can be narrowed down.

Toxic proteins accumulate in the brains of Alzheimer's patients. In the familial Alzheimer's patients, the accumulation mechanism is clear since there is a circumstantial relationship between the mutations and the identity of the defective proteins. In the random disease, on the other hand, the cause of the accumulation of proteins

Brain regions selected for temperature measurement using magnetic resonance spectroscopy are shown as overlays on standard MSR scans of the brain in different planes. 80 regions were selected in the cerebrum (shown in top view, top left, and side view, top right) and grouped into four concentric layers (top left). One region was selected in the hypothalamus (Hypo, shown in top, side and front view, bottom left of center) and one region in the thalamus (Thal, shown in front view, bottom right). The hypothalamus is an important area in the regulation of many things including temperature, sleep and biological clock. Credit: Nina Rzechorzek/Edinburgh Imaging/Brain
