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 of 71 studies on autism challenges this assumption and suggests that people with 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 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.

Microglial cells are the maintenance workers of the central nervous system (CNS), protecting against pathogens and pruning damaged neurons to help the brain maintain homeostasis. Considered immune cells, microglia work to protect the brain from before it is fully formed through its lifetime, but they aren’t infallible. The cells can be primed early on to respond in certain ways, making the microglia’s clean-up efforts less efficient. As other cells age, they can complicate microglial function, making them less effective.

But the underlying mechanism of how age and how their aging directly affects the brain is poorly understood—meaning that attempts to prevent or treat brain dysfunction may not be as effective as they could be, according to a multi-institutional collaboration led by Bo Peng and Yanxia Rao, both professors at Fudan University.

The team investigated how microglial cells change as they age in both male and female mice across their lifespans, finding what the researchers called “unexpected sex differences.” They also established a model to study aged microglial cells in a non-aged brain, revealing that aged-like contribute to even in young mice. The researchers published their findings in Nature Aging.

A study in the journal Cell sheds new light on the evolution of neurons, focusing on the placozoans, a millimeter-sized marine animal. Researchers at the Center for Genomic Regulation in Barcelona find evidence that specialized secretory cells found in these unique and ancient creatures may have given rise to neurons in more complex animals.

Placozoans are tiny animals, around the size of a large grain of sand, which graze on algae and microbes living on the surface of rocks and other substrates found in shallow, warm seas. The blob-like and pancake-shaped creatures are so simple that they live without any body parts or organs.

These animals, thought to have first appeared on Earth around 800 million years ago, are one of the five main lineages of animals alongside Ctenophora (), Porifera (sponges), Cnidaria (corals, sea anemones and jellyfish) and Bilateria (all other animals).

Scientists at Université Laval and the University of Lethbridge have succeeded in reversing certain cognitive manifestations associated with Alzheimer’s disease in an animal model of the disease. Their results have been published in the scientific journal Brain.

Although this has yet to be demonstrated in humans, we believe that the mechanism we have uncovered constitutes a very interesting therapeutic target, because it not only slows down the progression of the disease but also partially restores certain cognitive functions.

Summary: The revolutionary field of bio-computing is making waves as DishBrain, a neural system combining 800,000 living brain cells, learns to play Pong. Recognizing the pressing need for ethical guidelines in this emerging domain, the pioneers behind DishBrain have joined forces with bioethicists in a study.

The research explores the moral considerations around biological computing systems and their potential consciousness. Beyond its innovation, the technology offers vast environmental benefits, potentially transforming the energy-consuming IT industry.
