What does a tiny patch of salamander retina see when it watches a movie? Weizmann Institute scientists, together with Dr. Ronen Segev at Ben-Gurion University, performed this experiment - literally showing film sequences to snippets of live retina tissue and recording the interactions between their 100 or so active neurons. Seeing, as we know, is 3/4 interpretation and, contrary to common belief, this interpretation begins in the eye, before an image ever reaches the brain. Dr. Elad Schneidman and his colleagues found that unique patterns of neuron activity could be identified: There were…
Do you ever doubt your own memory? New research at the Institute suggests that some of the things we think we remember could be wrong. It seems that our brains are surprisingly willing to exchange a true memory for a false one, just on the basis of friends' claims. The scientists not only demonstrated just how easy it is to create false memories, they showed that the switch in memory has a signature pattern of brain activity. The most significant feature? They found strong connectivity between areas of the brain known to be involved in memory and learning, and the amygdala, which, among other…
Is having a beer and sandwich at the local pub the best way to improve your brain awareness? At least in the city of Rehovot one evening last week, those eating and drinking in a few select establishments got to hear Weizmann Institute neurobiology graduate students give informal talks and demonstrations. The event was a part of Brain Awareness week, an annual, international affair. The aim is not really to make people more aware of their brains (or their brains more aware), but to promote brain research. Some participated in an experiment in which they found that a smell can help imprint…
