The Bat-Tunnel: A Unique Setup for the Study of the Neural Basis of Navigation
REHOVOT, ISRAEL—May 27, 2021—The brain is often likened to a computer: neurons organized in complex circuits serving as its hardware; its software a plethora of codes that govern the neurons’ behavior. But sometimes the brain performs exceptionally well even when its hardware seems inadequate for the task; for example, the puzzle of how we and other mammals manage to navigate large-scale environments even though the brain’s spatial perception circuits are seemingly suited to representing much smaller areas. A team of researchers from the Weizmann Institute of Science, led by Prof. Nachum Ulanovsky of the Department of Neurobiology, tackled this riddle by thinking outside the experimental box. By combining an unusual research model – fruit bats – with an unusual setting – a 200-meter-long (about one-eighth of a mile) Bat-Tunnel – the team successfully revealed a novel neuronal code for spatial perception. The finding was reported in Science.
Jun 24, 2022... REHOVOT, ISRAEL—June 23, 2022—Weizmann Institute of Science researchers have found that people may have a tendency to form friendships with individuals who have a similar body odor. The researchers were even able to predict the quality of social interactions between complete strangers by first “smelling” them with a device known as an electronic nose, or eNose. These findings, published today in Science Advances, suggest that the sense of smell may play a larger role in human social interactions than previously thought.
Dec 21, 2023... REHOVOT, ISRAEL—December 21, 2023—All land mammals have tear glands in their eyes, but, until recently, the human tearing experience was considered unique. After all, humans are the only animals to shed tears while watching Beaches. Now a new Weizmann Institute of Science study reveals that human tears have much more in common with those of other animals than previously thought: Just as with the tears of mice and blind mole rats, they contain chemicals that reduce aggression in others. The study, published today in PLOS Biology, showed that sniffing women’s tears lowered brain activity related to aggression in men, reducing aggressive behavior.
