by Trinity College Dublin Figure 1. Spatial vision following rotenone insult. Rotenone was delivered bilaterally via intravitreal injection. Optokinetic responses were measured 2 months and 4 months post-injection using an OptoMotry virtual optokinetic system (Cerebral Mechanics). Bar charts represent the mean combined spatial frequency threshold. Error bars represent SD, ** p < 0.01, **** p...
by Massachusetts Institute of Technology Credit: Pixabay/CC0 Public Domain Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites—branch-like extensions that protrude from neurons—help to perform those computations. The researchers found that within a single neuron, different types of dendrites receive input from distinct parts...
by Griffith University Schematics illustrating the process for quantifying the amount of viable infectious C. pneumoniae present in various mouse tissues. (A) Mice were first intranasally inoculated with C. pneumoniae (i), some with epithelial injury and some without. Following either 24 h, 3 days or 7 days or 28 days post inoculation, selected tissues were collected and homogenized in...

Credit: public domain Advanced imaging technology developed by Yale researchers has helped them confirm that the destruction of brain synapses underlies the cognitive deficits experienced by patients with Alzheimer’s disease, according to a study published Feb. 17 in the journal Alzheimer’s & Dementia. For...
by Clare Collins, Erin Clarke, Rebecca Williams, The Conversation Credit: Shutterstock In the 1970s, low-carb diets were all the rage. The Dr. Atkin’s Diet Revolution book claimed carbohydrate restriction was a “high calorie way to stay thin forever.” Carbohydrates are found in breads, cereals and other grains, fruit, vegetables and milk. They’re also in ultra-processed fast foods, cakes, chips...

This is why evidence-based recommendations have long existed to advise people on how much exercise, and what type...
by Ilima Loomis, University of Chicago Medical Center Credit: Pixabay/CC0 Public Domain Proponents of LSD “microdosing”—taking small amounts of the drug at regular intervals—claim it can improve mood and cognitive function. But new research by the University of Chicago has not found evidence to support those claims. Harriet de Wit, Ph.D., Professor of Psychiatry and...
