    New German-Israeli Laboratory Inaugurated at the Weizmann Institute

    The just-established Max Planck – Weizmann Laboratory for Experimental Neuropsychiatry and Behavioral Neurogenetics, led by Weizmann's Prof. Alon Chen, will work to untangle the complex causes of cognitive, emotional, behavioral, and neurological disorders. Some 450 million people worldwide suffer from some form of mental illness.

    An End to the Winter Blues?

    Is the long winter bringing you down? Do TV and comfort food sound better than going out? If so, you might be among the 11 million Americans who get the winter blues. Remedies for seasonal depression are limited – but happily, the Weizmann Institute is working hard to shine light on depression's many causes, offering the hope of new, improved treatments.

  • Obesity, Stress, and Science

    The holiday season can be full of less-than-joyful issues such as stress and overeating. Weizmann scientists are studying related topics like obesity, metabolic disorders, and the body's stress response.

    Tiny Molecule Could Help Diagnose and Treat Mental Disorders

    Prof. Alon Chen and his team have identified a tiny molecule that not only impacts depression and anxiety, but also affects response to antidepressants – which currently help only a small number of patients. The finding could be a useful therapeutic molecule, and may even lead to a blood test for depression and related disorders.

    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.

    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.

    People With Anxiety Show Fundamental Differences in Perception

    Why are some people so much more anxious than others? Research shows that there are real differences in the way they perceive the world. In a process called overgeneralization, even neutral stimuli can remind the anxious person of emotionally charged stimuli, triggering anxiety. Greater understanding of the anxious brain could lead to better treatments.

    Disrupted Immunity in the Fetal Brain Linked to Neurodevelopmental Disorders

    New research from the Institute demonstrates that, in mice, disrupted immunity in the fetal brain is linked to neurodevelopmental disorders. The multi-department study revealed that when a pregnant female is attacked by external factors such as viruses, the brain of the fetus does not develop as it should, resulting in autistic and schizophrenic behavior.

    Receptive to Stress

    Prof. Alon Chen's lab discovered that a receptor, CRFR1, plays a surprising role in the body's stress response. In mice without CRFR1, females had trouble regulating temperature and blood sugar, while males were barely affected. The results could help develop treatments for regulating hunger or stress responses, including anxiety and depression.
