Most people think mental health is only about mood or therapy. The truth is bigger: your mental health shapes your lifespan.

Smells interpreted as taste!
When we eat or drink, we don’t just experience taste, but rather a ‘flavor’. This taste experience arises from a combination of taste and smell, where aromas from food reach the nose via the oral cavity, known as retronasal odor. Researchers have now shown that the brain integrates these signals earlier than previously thought – already in the insula, a brain region known as the taste cortex – before the signals reach the frontal cortex, which controls our emotions and behavior.
“We saw that the taste cortex reacts to taste-associated aromas as if they were real tastes,” explains the lead author. “The finding provides a possible explanation for why we sometimes experience taste from smell alone, for example in flavored waters. This underscores how strongly odors and tastes work together to make food pleasurable, potentially inducing craving and encouraging overeating of certain foods.”
The study involved 25 healthy adults who were first taught to recognize both a sweet taste and a savory taste through combinations of taste and smell. This was followed by two brain imaging sessions using functional magnetic resonance imaging (fMRI), in which the participants were given either a tasteless aroma or a taste without smell. The researchers trained an algorithm to recognize patterns in brain activity for sweet and savory tastes, and then tested whether the same patterns could be identified when the participants were only given aromas.
Single psilocybin trip delivers two years of depression relief for cancer patients
Psilocybin, the active ingredient in magic mushrooms, might just revolutionize how depression and anxiety are treated in cancer patients. In a groundbreaking trial, a single dose combined with therapy significantly reduced emotional suffering, and these effects often lasted over two years. As follow-up studies expand the research to multiple doses and larger samples, scientists are eyeing a possible new standard of care that merges psychedelics with psychological support.
Daniel Yon Explains Why Your Brain Is a Brilliant Illusionist
You probably think you’re listening to my voice right now. But what if I told you that you’re actually experiencing a sophisticated hallucination?
Perception isn’t the passive process that most of us imagine it to be, with our senses simply recording reality and sending it up to our brains for processing. Instead, our brains are constantly constructing theories about what’s going on around us—and sometimes our brains get reality wrong.
Here to explain this mind-bending way of looking at, well, the mind, is Daniel Yon, an associate professor of cognitive neuroscience and director of the Uncertainty Lab at Birkbeck, University of London. Daniel is also the author of a recent book called A Trick of the Mind: How the Brain Invents Your Reality.
Thank you so much for coming on to chat with us.
Thank you for having me.
So why don’t you start by telling me a little bit about your background and how it led you to write your latest book.
Yeah, so I’m an experimental psychologist and a cognitive neuroscientist, so that means my day job is to try and understand how your mind and brain work and how what happens inside your skull kind of makes the world that you live in.
