Past neuroscience and psychology studies have shown that people’s expectations of the world can influence their perceptions, either by directing their attention to expected stimuli or by reducing their sensitivity (i.e., perceptual acuity) to variations within the categories of stimuli we expect to be exposed to. While the effects of expectations on perceptions are now […]
Author: Frédéric Bernard, associate professor in neuropsychology, Université de Strasbourg We’ve all experienced it: you’re in the middle of a conversation, searching for a word, a name, or a title, and… nothing. You know you know it–you can almost feel it–but it just won’t come. This phenomenon, known as having a word “on the tip […]
You have probably heard the saying that the eyes are the windows to the soul, but now it turns out that they are also connected to how we breathe. Scientists have long studied the size of our pupils to understand attention, emotion and even medical conditions. But now, new research has surprisingly revealed that they […]
The complexity of the human brain—86 billion neurons strong with more than 100 trillion connections—enables abstract thinking, language acquisition, advanced reasoning and problem-solving, and the capacity for creativity and social interaction. Understanding how differences in brain signalling and dynamics produce unique cognition and behaviour in individuals has long been a goal of neuroscience research, yet […]
A predictive tool for determining the age at which individuals may develop mild cognitive impairment (MCI) or Alzheimer’s dementia (AD) has demonstrated the ability to predict MCI onset within 2.78 years and AD onset within 1.48 years. Developed by Florey Institute of Neuroscience and Mental Health researchers, collaborating with the Alzheimer’s Disease Neuroimaging Initiative (ADNI) […]
It has been known for a while that pregnancy changes the brain. We had available data for humans and other mammals showing that after becoming mothers, women’s brains had undergone such profound changes that it is sometimes compared to the reorganization the brain suffers during puberty. What’s new then? A recent study put a scientist […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. Alzheimer’s disease (AD) is a […]
Odi et amo. I hate and I love. Maybe you’re wondering why I do that. I do not know. But I feel it happening, and I suffer. So Catullus, famous ancient Roman poet, described the painful and puzzling feeling of love’s contradiction. And if you have ever experienced heartbreak, it’s very likely that you understand […]
Authors: Albert HiuKa Fok, Postdoctoral Fellow in Neuroscience, McGill University and Sabrina Chierzi, Research Associate, Neuroscience, McGill University Astrocytes — named for their star-like shape — are a type of brain cell as abundant as neurons in the central nervous system, but little is known about their role in brain health and disease. Many neurological […]
Authors: Sven Vanneste, Professor of Clinical Neuroscience, Trinity College Dublin and Elva Arulchelvan, Lecturer in Psychology and PhD Researcher in Psychology and Neuroscience, Trinity College Dublin Forgetting is part of our daily lives. You may walk into a room only to forget why you went in there – or perhaps someone says hi on the […]
