Dr. Ofer Yizhar, optogenetics pioneer, has used the tools of that field to successfully shut down a neuronal mechanism that helps form fearful memories in the mouse brain. After the procedure, the mice “forgot” that they had been previously frightened. This research, conducted with Prof. Rony Paz, may someday help extinguish traumatic memories in people.
In Issue No. 44 of WeizmannViews, we share the stress-response-related research of Prof. Rony Paz. He investigates how the brain processes stress - for example, how is a traumatic event encoded in such a way as to trigger PTSD? His work could lead to new and better treatments for mental illnesses.
The lab of Prof. Nachum Ulanovsky revealed that brain cells can guide us to our destination, even when we can’t see it. Scientific American’s Moheb Costandi reports on the research in Salon, also addressing related findings from other institutions and the question of whether the Ulanovsky cells are new types of cells, or represent more flexibility in other cells than previously suspected.
Bats - and humans - can find their favorite fruit stand (or coffee shop) even when it’s hidden behind a screen or buildings. How? Prof. Nachum Ulanovsky and team have now identified the neurons that point bats in the right direction, even when their destination is obscured. This could shed light on Alzheimer’s and other disorders.
The human brain is “limitless” – and yet, sometimes things go wrong. In this video, Prof. Noam Sobel, Dr. Assaf Tal, Prof. Michal Schwartz, Prof. Alon Chen, Dr. Tali Kimchi, Dr. Ofer Yizhar, Prof. Daniel Zajfman, and Prof. Yadin Dudai talk about studying the brain in health and disease, always learning “what it means to be human, what it means to think, what it means to remember.”
How do you know which way you’re going? In a first, Prof. Nachum Ulanovsky’s “bat lab” has identified the neurons that relate to direction. They found that bats’ brains contain a sort of 3D compass, enabling them to orient themselves in space. The team believes that the brains of non-flying mammals – including us – also have the 3D compass.
Dr. Alex Pine, a postdoc in cognitive neuroscience at the Weizmann Institute, conducted a study – overseen by Prof. Yadin Dudai – on people’s preferences, influencing those likes and dislikes via conditioning, using techniques like those Ivan Pavlov famously used with his dogs. As The Times of Israel reports, the scientists think their methods could help treat addictions and phobias more effectively.
Prof. Eytan Domany takes the stage to discusses the nature of memory, how we form memories, and how they change over time. He ties this into the dance about to performed by Israel’s Vertigo Dance Company at Lincoln Center, describing how the movements made by the dancers – seemingly repetitive, but slightly different each time – represent memory.
This three-minute video tells the story of Weizmann Institute researcher Prof. Nachum Ulanovsky, who studies free-flying bats to explore the brain's ability to work in three dimensions. His work with bats has considerable implications for human neuroscience.
The Weizmann Institute’s Prof. Michal Schwartz has been developing ways to use the immune system to treat devastating injuries. As Israel21c reports, this “powerhouse” is now studying whether an enhanced immune system can treat anxiety and other brain disorders, and even – most exciting of all – potentially cure Alzheimer’s.
