Aug 15, 2019... REHOVOT, ISRAEL—August 15, 2019—Extraterrestrial scientists landing in a football stadium would be struck by the sight of the crowd suddenly standing up and shouting in unison. In a similar manner, since the 1990s, researchers have observed a special pattern of neuronal activity in rodents: tens of thousands of nerve cells firing in unison in a part of the brain called the hippocampus. But, like alien scientists, the researchers have not been able to understand the “language” of the rodents’ minds when these mysterious synchronous bursts occurred. Recently, however, Weizmann Institute of Science researchers succeeded in recording these rapid bursts of activity – called “hippocampal ripples” – in the human brain, and were able to demonstrate their importance as a neuronal mechanism underlying the engraving of new memories and their subsequent recall. These findings appeared in Science.

Kadimastem Ltd., a biotechnology firm that develops cell therapies, said it has received “promising interim results” from a first group of patients treated with its new therapy for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, a fatal neurodegenerative condition that causes the loss of muscle control.
Sep 27, 2019... Fall is here and school is back in session. In the ninth episode of Weizmann in Focus, CEO Dave Doneson shares a simple tip to help prepare for success this academic year. Weizmann Prof. Noam Sobel, who studies the olfactory system, found that people who inhaled when presented with a problem-solving task performed better than those who exhaled. So, the next time you’re faced with a difficult task, take a deep breath!

Neurons in mice that lack an autism gene called CNTNAP2 do not differentiate well between social and nonsocial smells, according to a new study1. These neurons are located in the prefrontal cortex — a brain region that controls social behavior — and fire haphazardly.
The findings suggest that these differences drive the social problems in the mice and perhaps in autistic people with mutations in the gene. The results appeared 25 November in Nature Neuroscience.

JERUSALEM, July 29 (Xinhua) – Israeli scientists discovered how oxytocin, known as the “love hormone,” is restocked in the brain, the Weizmann Institute of Science (WIS) said Monday.
Oxytocin is responsible, for example, for a burst of happiness with parents gazing at their newborn baby or a loving couple exchanging glances.
However, oxytocin is not only a hormone of love but also plays a role in normal social interaction, birth and breastfeeding, control of stress and appetite and more.

Seconds before a memory pops up, certain nerve cells jolt into action in sync. This new finding sheds light on how the brain stores and recalls information.
Studying brain cells in action inside the human head is tricky. Putting electrodes in someone’s brain requires surgery. It’s not something researchers do without a good reason. The new study involved people who already had electrodes put in their brains for some medical purpose. These participants all had epilepsy. That brain disorder causes storm-like surges of electrical activity in the brain, known as seizures. Doctors put the electrodes in the patients' brains so they could pinpoint those surges.

A trailblazing study by Israeli researchers suggests that intestinal microbes may have a direct effect on the course of amyotrophic lateral sclerosis (ALS), the incurable, fatal neurodegenerative disease also known as Lou Gehrig’s disease that affected physicist Stephen Hawking.
Published today in Nature, the study by researchers at the Weizmann Institute of Science revealed that the progression of an ALS-like disease in lab mice was slowed after the mice received certain strains of gut microbes or substances known to be secreted by these microbes.

Gut microbes such as these were found to have altered levels in ALS patients
REHOVOT, ISRAEL—July 22, 2019—Researchers at the Weizmann Institute of Science have shown in mice that intestinal microbes, collectively termed the gut microbiome, may affect the course of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. As reported in Nature, progression of an ALS-like disease was slowed after the mice received certain strains of gut microbes or substances known to be secreted by these microbes. Preliminary results suggest that the findings on the regulatory function of the microbiome may be applicable to human patients with ALS.

Computer-enhanced MRI images of the brains of left-handed women identified two that were missing olfactory bulbs
REHOVOT, ISRAEL—November 6, 2019—Is a pair of brain structures called the olfactory bulbs, which are said to encode our sense of smell, necessary? That is, are they essential to the existence of this sense? Weizmann Institute of Science researchers recently showed that some humans can smell just fine, thank you, without said bulbs. Their finding – that around 0.6% of women, and more specifically, up to 4% of left-handed women, have completely intact senses of smell despite having no olfactory bulbs in their brains – calls into question the accepted notion that this structure is absolutely necessary for the act of smelling. The findings of this research, which were published in Neuron, could shake up certain conventional theories that describe the workings of our sense of smell.

If you’re ever unfortunate enough to require brain surgery, Israeli startup Nurami Medical has got you covered – literally.
The Haifa-based company has developed a patch made of synthetic, biodegradable nanofibers meant to be affixed to the dura mater – the protective membrane underneath the skull that keeps the brain and spinal cord safe – after cranial neurosurgery.
