Most preferences are thought to be conditioned by experience. (photo credit: Puppy image)
Free will isn’t what it’s cracked up to be, according to Israeli researchers. They say people may not have much control over what they like and dislike. That said, there may be a way to undo unwanted preferences, even phobias and addiction, by exploiting the fluidity of memory.
The standard scientific view is that people are born with few preferences. Most are thought to be conditioned by experience.

People who still believe the outdated notion that mental health conditions are “all in a person’s head” have yet another reason to stop believing the myth: According to a new study in the journal Current Biology, those with anxiety perceive the world differently – and it stems from a variance in their brains.
It all comes down to the brain’s plasticity, or its ability to change and reorganize itself by forming new connections. These inherent changes in the brain dictate how a person responds to stimuli, and researchers from the Weizmann Institute of Science in Israel found that people diagnosed with anxiety are less likely to be able to differentiate neutral or “safe” stimuli from threatening ones.
Feb 28, 2018... In just the past few years, understanding of the microbiome has transformed how we perceive diet and nutrition, and is already altering how we take care of ourselves. Weizmann Institute scientists from a range of disciplines – just some of which are immunology, neuroscience, biology, genetics, chemistry, machine learning, mathematics, and computer science – have led the way in microbiome research, regularly producing headline-making discoveries. Several of these researchers are also medical doctors, and their experience in working with patients helps move therapies more quickly from the lab to you.

Erasing unwanted memories isn’t yet possible. However, Israeli scientists are now reporting that they have succeeded in erasing one type of memory in mice – fear.
This new technique may one day help extinguish traumatic memories in humans – for example, in people with post-traumatic stress disorder, or PTSD.
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.

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.
