New research from the University of Missouri School of Medicine suggests there may be another way to treat cigarette cravings. Researchers found that theta-burst transcranial magnetic stimulation (TBS)—strong, rapidly fluctuating magnetic field pulses that can affect brain activity—can lead to improved self-control, reduced cravings and as a result, less smoking.

People with nicotine dependence tend to have significant structural and functional differences in the brain, compared to healthy non-smokers. Smoking cigarettes has been shown to be associated with less gray matter, which means they have less neurons and other cells in the brain.

Research suggests these differences may affect inhibitory control (IC), which is our control over automatic urges and response to stimuli—what enables humans to stop an impulsive reaction to something.

The opioid epidemic in the United States has exacted an incalculable toll on individuals and communities, creating an urgent need for alternative painkillers. The search for non-opioid treatments is crucial, not only to mitigate the risks of addiction and overdose, but also to develop pain management tools that remain effective without inducing tolerance and other challenging side effects in patients.

New research from the University of Chicago identified an alternative signaling pathway in the brain of mice that relieves pain, even in animals that have developed tolerance to opioids.

The study, titled “A Cholinergic Circuit That Relieves Pain, Despite Opioid Tolerance” and published in Neuron, also showed that pain relief through this route did not induce tolerance, did not create withdrawals symptoms after treatment was stopped, and did not activate reward systems, limiting risk for addiction and making it a viable path to developing effective, non-opioid pain relief.

You’re looking at a truck. You’re with a young child and he follows your gaze. He’s interested in the object you’re looking at without you pointing at it. This is called joint attention and it is one of the primary ways children learn to connect words with objects and acquire language.

Lack of joint attention is a core feature of autism. Until now, it was thought that stimulating joint attention in people with autism would help them express themselves verbally. But a meta-analysis of 71 studies on autism challenges this assumption and suggests that people with autism spectrum disorders may acquire language differently.

The study—by Laurent Mottron, a professor in the Department of Psychiatry and Addiction at Université de Montréal and a psychiatrist at the Hôpital en santé mentale Rivière-des-Prairies of the CIUSSS du Nord-de-l’Île-de-Montréal; Mikhail Kissine, a professor of linguistics at Université Libre de Bruxelles; and Ariane St-Denis, a medical student at McGill University—is published in Neuroscience & Biobehavioral Reviews.

“We’re all familiar with the Freudian idea that if we suppress our feelings or thoughts, then these thoughts remain in our unconscious, influencing our behaviour and wellbeing perniciously,” said Anderson. “The whole point of psychotherapy is to dredge up these thoughts so one can deal with them and rob them of their power.” It had become dogma in clinical psychology that efforts to banish thoughts or memories of a particular subject were counterproductive and made people think more about them, he said. “We challenge the view that thought suppression worsens mental illness.” https://www.ft.com/content/5495b3ee-6c08-4d89-a614-c0acb83aa9a6

The commonly-held belief that attempting to suppress negative thoughts is bad for our mental health could be wrong, a new study from scientists at the University of Cambridge suggests.
