Founded in 1944, the American Committee for the Weizmann Institute of Science develops philanthropic support for the Weizmann Institute in Israel, and advances its mission of science for the benefit of humanity.
Apr 07, 2020... Prof. Alon Chen – president of the Weizmann Institute and a leading neurobiologist who studies mental health – shares a two-part presentation in this videoconference with American Committee supporters.
Jun 15, 2020... REHOVOT, ISRAEL—June 15, 2020—During the pandemic lockdown, as couples have been forced to spend days and weeks in one another’s company, some have found their love renewed while others are on their way to divorce court. Oxytocin, a peptide produced in the brain, is complicated in that way: a neuromodulator, it may bring hearts together or it can help induce aggression. That conclusion arises from unique research led by Weizmann Institute of Science researchers in which mice living in semi-natural conditions had their oxytocin-producing brain cells manipulated in a highly precise manner. The findings, which were published in Neuron, could shed new light on efforts to use oxytocin to treat a variety of psychiatric conditions, from social anxiety and autism to schizophrenia.

A joint study by Tel Aviv University (TAU) and Weizmann Institute of Science researchers has yielded an innovative method for bolstering memory processes in the brain during sleep.
The method relies on a memory-evoking scent administered to one nostril. It helps researchers understand how sleep aids memory, and in the future could possibly help to restore memory capabilities following brain injuries or help treat people with post-traumatic stress disorder (PTSD) for whom memory often serves as a trigger.

Our mental health is always important, but more so than ever during these challenging times. Between the ongoing COVID pandemic, economic insecurity, social turmoil, and the like, rates of anxiety and depression are skyrocketing. How to cope? And why do we experience mental health issues in the first place?
As with the coronavirus, the answers are found in science.
The Weizmann Institute’s renowned neuroscientists do more than study the brain; they investigate how this most mysterious of organs responds to the world, processes our experiences, plays a role in emotional response, consolidates memories, becomes ill, and more. Our scientists also seek to develop effective medications and treatments. As Prof. Alon Chen – a renowned expert in neuropsychiatry and Weizmann Institute president – says, “I strongly believe that when we identify the mechanisms in the brain, we can use them to develop better ways to treat these conditions.”

If one were to objectively examine the topics being discussed in their social media feeds, that person might reach he conclusion that COVID-19 is all that’s going on in this world. It’s all anyone is talking about, and rightfully so. The effects of this pandemic on the human species will be discussed and analyzed for many years to come.
What is not being discussed enough, however, are the effects COVID is having on our mental health. Loneliness, anxiety, depression, hopelessness; these are just some of the emotions a global pandemic can, and are causing – and it’s important that we acknowledge it.
Jan 19, 2021... Prof. Rony Paz, Head of the Department of Neurobiology, speaks about our still-mysterious brains. While they can do remarkable things, they also produce conditions such as PTSD, anxiety, autism, and the like – all of which are on the rise worldwide.
Jan 27, 2021... REHOVOT, ISRAEL—January 27, 2021—Chronic stress could be the prevailing condition of our time. In the short term, our jaws or stomachs may clench; in the long term, stress can lead to metabolic disease and speed up diseases of aging, as well as leading to more serious psychological disorders. The physical manifestations of stress originate in the brain, and they move along a so-called “stress axis” that ends in the adrenal glands. These glands then produce the hormone cortisol. When the stress axis is continually activated, changes occur in the cells and organs along the way, and the continual production of cortisol then substantially contributes to the symptoms of chronic stress.

A new study found a secret gene deep in our kidneys that aids with stress removal from cells.
Scientists at the joint neurobiology lab at the Weizmann Institute of Science with the Max Planck Institute of Psychiatry in Germany mapped out gene sequences for cells traveling from the brain, when stress is activated, down to the adrenal glands in the kidneys, to track how and where stress develops, to get a better idea of how to treat stress-related health problems.

May 18, 2021... REHOVOT, ISRAEL—May 18, 2021—A natural food supplement reduces anxiety in mice, according to a new Weizmann Institute of Science study. The plant-derived substance, beta-sitosterol, was found to produce the calming effect both on its own and in synergic combination with a common antidepressant, fluoxetine (brand name Prozac). If these findings, published in Cell Reports Medicine, are confirmed in clinical trials, they could point the way toward the use of beta-sitosterol as a treatment for relieving anxiety in humans.
Aug 09, 2021... REHOVOT, ISRAEL—August 9, 2021—During the six weeks between the end of the first Covid-19 outbreak in Israel and the beginning of the second one (late April to early June of 2020), researchers at the Weizmann Institute of Science initiated a study that sought to assess and understand the mental toll of the pandemic on the country’s adult population. The study included more than 12,000 responses from nearly 5,000 respondents to digital questionnaires.
