Why does time move slowly sometimes, and quickly at others? 🤔
Instead, it seems to fly by at one moment and practically stand still at others. This distorted sense of time may be caused, in part, by brain cells getting tired, according to a new study.
We have only very recently begun to understand how our brains perceive time. It was only in 2015, that researchers found the first evidence of neurons whose activity fluctuates with our perception of time. But it wasn't clear if these neurons, found in a small brain region called the supramarginal gyrus , were keeping accurate time for the brain, or creating a subjective experience of time.
After this, the participants were shown another circle for a set period of time as a"test stimulus." They were then told to listen to white noise for a certain amount of time and asked if the test stimulus was longer or shorter than the white noise. The idea is that this repetition"tire[d] out neurons," that are sensitive to that time duration, said lead author Masamichi Hayashi, a cognitive neuroscientist at the Center for Information and Neural Networks at the National Institute of Information and Communications Technology in Japan. But"other neurons that are sensitive to other durations [were] still active."

How Consultants Project Expertise and Learn at the Same TimeFor consultants, work is largely a performance. Like skillful actors, they use a combination of “backstage” preparation and “front stage” performance to make clients believe the story they want to tell. But consulting often depends on in-depth situational knowledge that consultants simply can’t have when they start a project. How do consultants learn about their clients’ challenges while also showing they have the expertise to solve them? In a study of consultants over almost two years, the authors found several techniques that these professionals use.
