Autism

a. Brain structure comparisons of the following mice: Left: BTBR/R and B6 (normal mouse), Center: Comparison of BTBR/J and B6, Right: BTBR/J and BTBR/R. b. Diffusion tensor imaging to compare differences in nerve fibers. Red indicates the brain regions that were either bigger or had increased numbers of nerve fibers in BTBR/J mice in comparison to either B6 (left and center images) or BTBR/R (right image). Conversely, blue indicates brain regions in BTBR/J mice that were comparatively smaller or had decreased numbers of nerve fibers. These scans revealed particularly significant differences between BTBR/J and BTBR/R mice’s corpus callosum.

Ancient virus genome drives autism?

Mice engage in grooming behavior, experiencing a phenomenon researchers call pleasant touch. Researchers from the Washington University Center for the Study of Itch and Sensory Disorders have identified a specific neuropeptide and a neural circuit that transmit pleasant touch from the skin to the brain. The findings eventually may help scientists better understand and treat disorders characterized by touch avoidance and impaired social development.
