The Cause of Depression Is Probably Not What You Think
Depression has often been blamed on low levels of serotonin in the brain. That answer is insufficient, but alternatives are coming into view and changing our understanding of the disease.
The Year in Biology
Momentum for new ideas in Alzheimer’s research joined advances in neuroscience, developmental biology and origin-of-life studies to make 2022 a memorable year of biological insights.
How the Brain Distinguishes Memories From Perceptions
The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.
What Causes Alzheimer’s? Scientists Are Rethinking the Answer.
After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.
