What gives rise to human consciousness? Are some parts of the brain more important than others? Scientists began tackling these questions in more depth about 35 years ago. Researchers have made progress, but the mystery of consciousness remains very much alive. In a recently published article, I reviewed over 100 years of neuroscience research to […]
One of the most famous quotes that Santiago Ramón y Cajal wrote in his work “Rules and tips on scientific research” was “Every man can, if he so desires, become the sculptor of his own brain.” . However, the use of dental material as mud and stones to model or repair sculptures probably sounded like […]
Author: Mohamady El-Gaby, Postdoctoral Neuroscientist, University of Oxford For decades, neuroscientists have developed mathematical frameworks to explain how brain activity drives behaviour in predictable, repetitive scenarios, such as while playing a game. These algorithms have not only described brain cell activity with remarkable precision but also helped develop artificial intelligence with superhuman achievements in specific […]
Author: Albert HiuKa Fok, Postdoctoral Fellow in Neuroscience, McGill University The puzzle of memory has intrigued philosophers and intellects for a very long time. Plato and Aristotle believed that memory was found only in the realm of the soul and the mind, but there was nothing corporeal or physical about it. Memory is closely tied […]
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 […]
