ἀνθρώποισι πᾶσι μέτεστι γινώσκειν ἑωυτοὺς καὶ σωφρονεῖν.
Our hands and fingertips are amazingly sensitive to texture. We can easily distinguish coarse sandpaper from smooth glass, but we also pick up more subtle differences across a wide range of textures, like the slick sheen of silk or the soft give of cotton.

When a person takes a puff on a cigarette, nicotine floods into the brain, latching onto receptors on the surface of neurons and producing feelings of happiness. But nicotine does not simply stay on the surface of cells — the drug actually permeates into neural cells and alters them from the inside out. Now, a team of scientists has developed a protein sensor that glows in the presence of nicotine, allowing the researchers to observe nicotine’s movements in cells and reveal more about the nature of nicotine addiction.

Neural stimulation is a developing technology that has beneficial therapeutic effects in neurological disorders, such as Parkinson’s disease. While many advancements have been made, the implanted devices deteriorate over time and cause scarring in neural tissue. In a recently published paper, the University of Pittsburgh’s Takashi D. Y. Kozai detailed a less invasive method of stimulation that would use an untethered ultrasmall electrode activated by light, a technique that may mitigate damage done by current methods.

Experts from the Basque research centre BCBL have shown for the first time that the way in which the activity of two brains is connected depends on whether the dialogue takes place in the native language or in a foreign language. Continue reading “The language of conversation impacts on the ‘synchronization’ of our brains”
Here we present selected parts of the very interesting paper titled “Neurosciences in byzantine era” (Journal of Neurology & Stroke, Volume 8 Issue 4 – 2018), by Stavros J. Baloyannis. Continue reading “Neurosciences in the Christian Roman Empire”
Poor sleep has long been linked with Alzheimer’s disease, but researchers have understood little about how sleep disruptions drive the disease. Continue reading “Sleep deprivation accelerates Alzheimer’s brain damage”
