Here's a short selection of our favorite neuroscience stories from the last week!
Fully characterizing how the brain goes awry in disease states depends heavily upon the ability to visualize specific neuron subtypes. Thankfully, neuroscience has been revolutionized by microscopy tools such as SIM, dSTORM, and STED. In this article, we explore how these techniques are fueling the field's progress.
1. We are all drawn to happy places, but what are the brain mechanisms behind this? Scientists identified the brain cells that could be responsible.
2. The herb kratom is increasingly being used to manage pain and treat opioid addiction, but it’s not safe to use as an herbal supplement, according to new research.
3. Data from over 12,000 multiple sclerosis (MS) patients formed the basis of a study which investigated the population's vaccination behavior in relation to MS. It showed that five years before their diagnosis, MS patients were actually less likely to receive vaccinations than comparator groups, ruling out vaccines as a risk factor.
4. A chimeric mouse model has made it possible to learn how key human brain cells respond to Alzheimer's, vaulting a major obstacle in the quest to understand and one day vanquish it.

5. Researchers examining the brains of 324 men and women with a special form of magnetic resonance imaging called diffusion tensor imaging have identified interesting differences in the wiring of general knowledge buffs' brains.
