...ommunicate directly with the brain. Current research focuses on one very unusual type of ganglion cell that senses light directly. These neurons drive reflexive responses to daylight, such as synchronizing biological clocks to the rising and setting of the sun. Berson's discovery of that third light-sensing...

...n Iraq. The veterans suffered from a particular aspect of PSTD known as "acoustic startle" -- a form of hyper arousal that causes an uncontrollable reflexive response provoked by sudden loud sounds. Two-minute video clips were specifically tailored for each veteran to re-enact, as closely as possible, th...

"These findings suggest that training the central control process---the brain and reflexive responses---may be necessary to counter the fatigue induced ACL injury risk," said McLean, who also has an appointment with the U-M Bone & Joint Injur...
