‘Genetic doppelgangers:’ Emory research provides insight into two neurological puzzles

An international team led by Emory scientists has gained insight into the pathological mechanisms behind two devastating neurodegenerative diseases. The scientists compared the most common inherited form of amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD) with a rarer disease called spinocerebellar ataxia type 36 (SCA 36). Both of the diseases are caused by abnormally expanded and strikingly similar DNA repeats. However, ALS progresses quickly, typically killing patients within a year or two, while the disease Read more

Emory launches study on COVID-19 immune responses

Emory University researchers are taking part in a multi-site study across the United States to track the immune responses of people hospitalized with COVID-19 that will help inform how the disease progresses and potentially identify new ways to treat it.  The study is funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The study – called Immunophenotyping Assessment in a COVID-19 Cohort (IMPACC) – launched Friday. Read more

Marcus Lab researchers make key cancer discovery

A new discovery by Emory researchers in certain lung cancer patients could help improve patient outcomes before the cancer metastasizes. The researchers in the renowned Marcus Laboratory identified that highly invasive leader cells have a specific cluster of mutations that are also found in non-small cell lung cancer patients. Leader cells play a dominant role in tumor progression, and the researchers discovered that patients with the mutations experienced poorer survival rates. The findings mark the first Read more

Going meta

Just before Thanksgiving, Slate writer Katy Waldman had a piece summarizing the growing body of evidence that linguistic metaphors reflect how we actually use our brains.

Emory neuroscientist Krish Sathian and his colleagues have been major contributors to this field (“conceptual metaphor theory”). In 2012, he and Simon Lacey published their brain imaging study, which found that when people listened to sentences involving touch metaphors (“having a rough day”), the parts of the brain involved in the sense of touch were activated. NPR’s Jon Hamilton talked about these findings with him in 2013.

At the recent Society for Neuroscience meeting, Sathian discussed his team’s ongoing work on how the brain processes metaphors that make references to body parts (head, face, arm, hand, leg, foot), as part of a nano symposium on language.
