A free neuroscience textbook
Today I want to tell you about an excellent neuroscience textbook that you can read online absolutely for free! Neuroscience: Canadian 2nd Edition Open Textbook” is a very complete, typical undergraduate-level treatment of its subject, divided into four units: 1. Neuroscience: The Basics; 2. Neurodegeneration; 3. Fundamental Neuroscience Techniques (and when to use them); and 4. Emergent Topics in Neuroscience. Unit 1 covers not only the anatomy and physiology of the entire nervous system, but also those of the system, which is so closely linked to it. Unit 3, on neuroscience techniques, is fairly extensive, explaining highly complex techniques such as optogenetics. Unit 4 delves into subjects that are getting a lot of attention from cognitive scientists today and that you’d never have seen in a neuroscience textbook 10 or 20 years ago, such as the beneficial effects of art, exercise and meditation on the brain. The book also includes quiz questions and links to videos on other websites. (more…)

Neurons as Works of Art
If you visit the website that I’m going to tell you about today, you’re likely to kill a lot of time there, as I just did. But if visiting a museum to enjoy beautiful art isn’t really killing time, then neither is visiting NeuroArt® —an online gallery of gorgeous images of neurons and the brain, produced with dyes, tracers and a variety of other technical methods.

Who Fact-Checks the Fact-Checkers?
That’s not so simple a question as it may seem, because although we are often rightfully warned against people who claim to have “done their research” on some subject or other and to have discovered unbelievable secrets about it, we are also often asked to accept fact checkers as sources of absolute truth, when they’re really not. They’re just ordinary journalists who are being paid to do their jobs as best they know how while dealing with complex, specialized disciplines and concepts with which they are no more familiar than you or I. So in the end, what do fact checkers offer us? Their own subjective accounts of small slices of reality that they think they have understood and that we hope most of them are presenting in a responsible way—in other words, a far cry from what is suggested by the categorical labels of “true” and “false” that all too often litter fact checkers’ articles on complex subjects such as the human brain, or Covid-19.

Rediscovery of the traces of another hominin species from the same time as Lucy
The earliest traces of bipedalism are associated with Australopithecus afarensis, the species of the famous fossil Lucy. But if a study published recently in the journal Nature is accurate, scientists have just authenticated different traces of another bipedal species that lived at exactly the same time. (more…)

Ultrasound localization microscopy provides unprecedented view of blood flow in the brain
The technologies that can now be used to image various aspects of the anatomy and physiology of the brains of living human beings are triumphs of scientific and technical inventiveness. One of the newest of these techniques is ultrasound localization microscopy, which was recently used to provide the first-ever dynamic images of blood flowing through the capillaries of the brain. This new ability to view blood circulation in the brain so rapidly and precisely opens opportunities for a better understanding of the irrigation of the brain and the problems that can arise with it, such as aneurysms.
