The Roots of Fear: Understanding the Amygdala (ucdavis.edu)
Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists at the University of California, Davis have identified new clusters of cells with differing patterns of gene expression in the amygdala of humans and non-human primates. The work could lead to more targeted treatments for disorders such as anxiety that affect tens of millions of people.
What's so special about the human brain? (nature.com)
Torrents of data from cell atlases, brain organoids and other methods are finally delivering answers to an age-old question.
Study Reveals the Brain Divides the Day into Chapters Like a Book (sciencealert.com)
Life can feel like a novel some days, full of romance and mystery, and perhaps a touch of horror or even a little fantasy. So perhaps it comes as little surprise that the human brain keeps track of narratives in discrete chunks not unlike the chapters of a book.
Brain detects patterns in the everyday: without conscious thought (nature.com)
The human brain is constantly picking up patterns in everyday experiences — and can do so without conscious thought, finds a study1 of neuronal activity in people who had electrodes implanted in their brain tissue for medical reasons.
The Human Brain in Numbers: A Linearly Scaled-Up Primate Brain (nlm.nih.gov)
The human brain has often been viewed as outstanding among mammalian brains: the most cognitively able, the largest-than-expected from body size, endowed with an overdeveloped cerebral cortex that represents over 80% of brain mass, and purportedly containing 100 billion neurons and 10× more glial cells.
