Think nothing. Your brain is always on, as your heart, liver or kidneys are, so thinking nothing is the closer you’ll get to a resting state for it, because even when we sleep the brain is quite active. We know that the interactions among different brain regions can be studied with functional magnetic resonance imaging […]
Smartphones are our everyday travel companion. Be it for work, in our leisure time or to connect with family and friends they accompany us. However, for some this utility turns into a need. A need such that it could even be called addiction. New research from Heildelberg University has shown that smartphone addiction is also […]
A team of scientists at two British universities, Bath and Bristol, have developed neuron-like chips that could revert the neurological damage caused by neurodegenerative diseases like Alzheimer’s. These chips do not only resemble neuronal function but are also very efficient and low energy consuming. Can we ask for more? Obviously, when I say chip, I […]
I n a 2017 interview, the famous actress Kate Walsh – whom you may know from the TV show Grey’s anatomy – reported the following: “ I started having more cognitive difficulties. It felt like aphasia [language problems] , but it was not just not being able to find words; I would lose my train […]
Families with members with autism spectrum disorders (ASD) are easy prey for scam artists who offer them magical solutions and therapies not backed by science. Many of these pseudotherapies are included in the so-called alternative medicine, a misnomer because they are not medical treatments and do not meet the same criteria required of a medicine: […]
The cerebral cortex is a limited resource. Evolution has employed some impressive tricks to increase the amount of cortex available, such as folding it, therefore getting more surface in the same volume, or putting different things in the left and right hemisphere instead of duplicating them, thus enlarging its capacity to accommodate specific functions such […]
Some people are cool not getting enough sleep. I am, however, not one of those. After almost two years of sleep deprivation I can say I am close to becoming the grumpy dwarf from Snow White. And up until now, I didn’t have a reason to justify why me and not others. But Sahil Bajaj […]
Cortical neurons often fire together as a group, rather than independently, and these coactive groups, also known as neuronal ensembles (or chains, assemblies, attractors, clicks, motifs, songs, bumps, etc.), could constitute emergent functional units of the brain, as modular building blocks of memories, thoughts, motor programs, computations, or perceptual or mental states. In order to […]
As one of those people who REALLY love to sleep -and doesn’t get close to enough of it- I am always interested to read on the topic. What I didn’t expect was to read about sleeping fish and how that relates to its origin . But let’s get down to the details, because if the […]
Autism spectrum disorders (ASD) have among their diagnostic characteristics problems for communication and social interaction. The typical example is the difficulty to understand the facial expressions or the body language of other people, but in addition to these aspects mediated by the visual system there may be other senses affected and, in fact, it has […]
