Parkinson’s disease is characterized by neuronal loss in the brain’s substantia nigra region. What if another cell type, namely, astrocytes, could replace them? The work of two research groups recently published Zhou, H. et al. Cell 181, 590–603.e16 (2020). shows that, at least in mice, transforming astrocytes (a non-neuronal cell type in the brain) into […]
We all know some of the symptoms of sleep deprivation: bad mood, tiredness…but when bad comes to worst, this lack of sleep can even lead to death. A recently published article by neuroscientists at Harvard Medicine School have shown, in flies, that lack of sleep might be killing from the gut. Because flies share many […]
Amyloid plaques are a hallmark of some neurodegenerative diseases like Alzheimer’s or Parkinson’s. Even though the exact role of amyloid protein in the disease is not clear, being able to follow amyloid protein misfolding and plaque formation could be a step forward for the study of the disease. Now, Matthew Lew’s lab has developed a […]
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 […]
