    Mice in a ""Big Brother"" Setup Develop Social Structures

    How does a social animal gain dominance over its fellows? With a unique setup, Weizmann scientists were able to closely study mice living in almost-natural conditions and observe regulation of social behavior, including selection of a leader. This work could also provide insight into the social aspects of schizophrenia and autism.

    Science on the Brain

    Weizmann Institute and New York University scientists are collaborating in their explorations of the inner workings of the brain, leading to new knowledge and possibly new therapies. 

  • The President's Report 2004

    A report from the president of the Weizmann Institute of Science about the state of the Institute in 2004, including highlights in nanoscience, neuroscience, cancer therapies, advanced imaging, education, and more.

    Learning a New Sense

    Weizmann Institute researchers find that humans are able to learn to use “whiskers” to locate objects in their environment, much as rats do. The findings give new insight into the process of sensing and may point to new avenues in developing aids for the blind.

  • Tears-Are-a-Turn-Off-thumb
    Tears Are a Turnoff

    Prof. Noam Sobel has found that emotional signals are chemically encoded in our tears. He demonstrated that merely sniffing a woman's tears reduces testosterone and sexual arousal in men.

    Stress-Coping Mechanism Helps Mice Make New Friends

    What makes us reluctant or willing to leave our social comfort zones? Prof. Alon Chen and his team in the Department of Neurobiology found that a molecule that helps the brain cope with stress appeared to act as a ""social switch"" in mice, causing them to either increase interactions with ""friends"" or seek to meet ""strangers."" Since a similar system exists in the human brain, the findings may help explain why some people are better at making new friends, and shed light on the social difficulties experienced by those with autism, schizophrenia, and more.

    A 3D Compass in the Brain

    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.

    Temporary Disconnects Shed Light on Long-Term Brain Dysfunction

    Dr. Ofer Yizhar is a pioneer in optogenetics, which employs light to manipulate the living brain. He is using it to study long-range communication across the brain, and since mental and neurological diseases may result from changes in such extended connectivity, his work could result in better understanding of mental illness – and better treatments.
