    Could Erasing Traumatic Memories One Day Eradicate PTSD?

    Israel21c reports on research by optogenetics pioneer Dr. Ofer Yizhar. Working with Weizmann colleague Prof. Rony Paz and others, Dr. Yizhar showed that weakening the communication between two parts of the brain reduced fear levels in mice. “This new technique may one day help extinguish traumatic memories in humans – for example, in people with post-traumatic stress disorder, or PTSD.”

    Mapping the Social Landscape

    Whether we’re playing a team sport or just strolling through the park, we’re continually aware of the positions of those around us – and where each is heading. Scientists have, in recent decades, pinpointed neurons called “place cells” in our brains that encode our own location in the environment, but how our brains represent the positions of others has been a mystery. Published in Science, new Weizmann Institute of Science research in bats reveals a sub-population of neurons that encode the specific locations of other bats that are flying nearby.

    100 Bats and a Long, Dark Tunnel: One Neuroscientist’s Quest to Unlock the Secrets of 3D Navigation

    On a sun-parched patch of land in Rehovot, Israel, two neuroscientists peer into the darkness of a 200-metre-long tunnel of their own design. The fabric panels of the snaking structure shimmer in the heat, while, inside, a study subject is navigating its dim length. Finally, out of the blackness bursts a bat, which executes a mid-air backflip to land upside down, hanging at the tunnel’s entrance.
