Weizmann Institute research shows our brain's sense centers are continuously active. In the absence of a stimulus, however, their electrical activity remains in 'screen saver' mode.
Even when our eyes are closed, the visual centers in our brain are humming with activity. Weizmann Institute scientists and others have shown in the last few years that the magnitude of sense-related activity in a brain that’s disengaged from seeing, touching, etc., is quite similar to that of one exposed to a stimulus. New research at the Institute has now revealed details of that activity, explaining why, even though our sense centers are working, we don’t experience sights or sounds when there’s nothing coming in through our sensory organs.

May 04, 2020... Prof. Noam Sobel, of the Department of Neurobiology, is a leading authority on how olfaction affects human behavior and health. Data emerging from the coronavirus pandemic show that many patients experience a temporary loss of their sense of smell. So dramatic is this loss that, in some countries, patients who report a sudden loss of olfactory acuity are declared to be coronavirus patients, even without further testing. The CDC recently added olfactory loss as a formal symptom of COVID-19.

Humans touch their own faces often because they are subconsciously smelling themselves for a variety of reasons, scientists believe. The team also conducted a survey to see whether people subconsciously smell themselves and others, and found more than half of the participants had smelled a stranger.
The authors of the article titled Are humans constantly but subconsciously smelling themselves? published in the journal Royal Society journal Philosophical Transactions B reviewed existing studies to understand if and why humans smell themselves.

If you’re getting bored in quarantine, here’s a fun new hobby to try: sniffing stuff in your kitchen. Two international projects are asking ordinary people to rate the scents of household items in order to gather data on one of COVID-19’s more mysterious symptoms: anosmia, the loss of the ability to smell.
It’s still unclear to scientists how widespread anosmia is among COVID-19 patients, which typically causes a fever, dry cough and difficulty breathing. And whether it can be a useful way to track the spread of the disease is still to be determined — leaving researchers eager to gather as much data on the symptom as possible.

COVID-19 has separated us from the world in surprising ways. Yes, we all miss our friends and loved ones, and we miss going to restaurants and stores and movies and concerts. But there’s another pastime that COVID-19 has deprived us of, even if we don’t realize it: the simple pleasure of subconsciously touching our own faces and sniffing our hands.
As COVID-19 spread, the Centers for Disease Control and Prevention warned people against touching their faces — and for good reason: A 2006 study suggested that nearly 25 percent of respiratory disease transfer could be attributed to people touching their faces.

An unconscious person’s response to odors after a serious brain injury may be a simple yet powerful signal of how aware they are and how likely they are to survive and recover, a new study suggests, relying on responses to the scent of shampoo and the stench of rotting fish.
Patients who survive brain damage from trauma, stroke, or heart attack are plunged into forms of unconsciousness that vary from minimal consciousness to unresponsive wakefulness, sometimes called a vegetative state. Specialists trying to tell who is in which state have fared only a little better than a coin flip: About 4 in 10 people thought to be unconscious are actually aware.
Apr 30, 2020... REHOVOT, ISRAEL—April 30, 2020—If an unconscious person responds to smell through a slight change in their nasal airflow pattern, they are likely to regain consciousness. This is the conclusion from a new study conducted by Weizmann Institute scientists and colleagues at Israel’s Loewenstein Rehabilitation Hospital. According to the findings, published in the journal Nature, 100% of the unconscious brain-injured patients who responded to a “sniff test” developed by the researchers regained consciousness during the four-year study period.

For a single ant, the world can be an overwhelmingly big place. To safely navigate their environs, ants rely on collective cognition.
According to a new study, published Tuesday in the journal eLife, collective brainpower makes seemingly chaotic environs navigable.
“Cooperation is a common means by which animals can increase their cognitive capacity, and we were intrigued as to whether this cooperation allows ants to extend the range of environments in which they can efficiently collect food,” first study author Aviram Gelblum, a postdoctoral fellow at the Weizmann Institute of Science in Israel, said in a news release.
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.
