Despite not having been able to talk for 15 years, a paralyzed man can now communicate using electrodes implanted in his brain. Continue reading Scientists Detect Brain Signals to Help a Paralyzed Man Speak
Researchers have grown a miniature brain that also develops eye-like structures. Continue reading Development in a Dish: Scientists Grow a Combined Brain and Eye Organoid
by Isabella Grabskifigures by Allie Elchert There are many ways in which our brains track, process, and use time to help us function. One mechanism by which they do so is motor timing. Motor timing relates to our ability to carry out any physical task where time estimation, often done unconsciously, is needed to successfully coordinate our movements. Take, for instance, the task of playing a … Continue reading How Our Brains Estimate Time
by Hannah Smithfigures by Xiaomeng Han If you ask any aging researcher, “What is the easiest way to make an animal in the lab live longer,” they will likely say “change what, or how much, they eat.” However, new research shows that it’s not just the food we eat that changes how we age, but that aging is also affected by the food we smell. … Continue reading The Surprising Influence of Smell on Aging
by Xiaomeng Han If your best friend Betty told you that she has a sore throat, a runny nose, and has lost her sense of smell or taste, you might immediately recognize the symptoms of COVID-19. But what if she had become very forgetful lately, instead? Recent emerging evidence suggests that SARS-CoV-2, the virus that causes COVID-19, can infect cells in the brain. In fact, … Continue reading An Unexpected Invasion: How SARS-CoV-2 affects the human brain
Researchers at the Pasteur Institute in Paris identified a molecular pathway that links the gut microbiome to mood disorders. Continue reading Bacteria in the Gut can Influence Brain Function and Mood Disorders
Zebrafish shed insight into how the brain responds to social isolation: their neuronal gene activity changes depending on how many others are around them. Continue reading The Effect of Social Isolation on the Zebrafish Brain
For dogs, the rhinarium is the furless tip of their snouts. Researchers have found that this cold and wet small surface area may detect heat even from far away. Continue reading Dog Noses Can Sense Warmth Far Away
Land animals are often smarter than aquatic animals but it is still unclear exactly how their cognition developed. In @NatureComms, @malcommaciver and #UgurcanMugan found that complex landscapes and the ability of land animals to see more in air compared to fish in water may have led to planning circuitry in the brains of land animals.

Researchers from the University of Sussex recently found that wood ants seem to store long-term and short-term memories in different brain hemispheres. They found this by studying ants as they were conditioned to associate a visual input with food.
