Bionic Legs With Sensory Feedback Blur the Line Between Biology and Technology
Scientists successfully characterized and implemented bionic leg technology with three amputees. The results appear in today's issue of Science Translational Medicine. The researchers show that as the amputees feel that their bionic legs are part of their own body, the mental effort required to control them is lessened.

Hearing Voices in Schizophrenia Could Start in Infancy
To investigate the biological origins of hearing "voices" in patients with schizophrenia, researchers used ultra-high field imaging to compare the auditory cortex of schizophrenic patients with healthy individuals. They found that schizophrenic patients had abnormal tonotopic organization of the auditory cortex, which is a process that begins early in life.

Fish Fathers Exhibit “Baby Brain”
Many new parents are familiar with terms like "baby brain" or "mommy brain" that hint at an unavoidable decline in cognitive function associated with the hormonal changes of pregnancy, childbirth, and maternal caregiving. A new study of parental care in stickleback fish is a reminder that such parenting-induced changes in the brain and associated shifts in cognition and behavior are not just for females--and they're not just for mammals either.
