Human astrocyte. The vivid color is from GFP, not drugs.
The real news is the importance of a type of brain cells called astroglia, which have long been ignored while researchers focus on neurons. THC, the psychoactive chemical in marijuana, impairs working memory by connecting to astroglia, according to a new paper published in Cell. So the star-shaped astroglia turn out to be the real star of this study.
New research suggests the mere act of walking through a doorway helps people forget, which could explain many millions of confusing moments that happen each day around the world. A study published recently in The Quarterly Journal of Experimental Psychology found that participants who walked through doorways in a virtual reality environment were significantly more likely to forget memories formed in another room, compared with those who traveled the same distance but crossed no thresholds.
