Juan Valverde de Amusco’s anatomical drawings in 1556 corrected some earlier errors while making anatomy more accessible.

by SUKANYA CHARUCHANDRA It wasn’t until the latter half of the 13th century that human dissections became acceptable in Italy. Previously, both the Roman Empire and Islamic law had prevented the dissection of humans and its depiction. While the Greek surgeon Galen’s anatomical drawings from the second century had been preserved and studied until theContinue reading “Juan Valverde de Amusco’s anatomical drawings in 1556 corrected some earlier errors while making anatomy more accessible.”

The Gut of Mice Communicates with the Brain Through the Vagus Nerve, forming a possible basis for a 6th Sense

by SUKANYA CHARUCHANDRA Previous research has shown that the gut-brain connection, which refers to signaling between the digestive and the central nervous systems, is based on the transport of hormones, but a study published today (September 21) in Science suggests there may be a more direct link—the vagus nerve. This research presents “a new setContinue reading “The Gut of Mice Communicates with the Brain Through the Vagus Nerve, forming a possible basis for a 6th Sense”

A protein in skeletal muscles helps mice recover from sleep deprivation.

by SUKANYA CHARUCHANDRA The protein Bmal1, which helps regulate the body’s internal clock, is found in especially high levels in the brain and in skeletal muscles. Mice completely deficient in Bmal1 were known to suffer from sleep impairments, but the specifics at play weren’t clear. At the University of California, Los Angeles, Ketema Paul andContinue reading “A protein in skeletal muscles helps mice recover from sleep deprivation.”

LRRK2 enzyme is implicated in even more Parkinson’s disease cases than originally realized, suggesting that inhibitors of the enzyme could treat more patients.

by SUKANYA CHARUCHANDRA Even when Parkinson’s patients don’t have mutations in a gene called LRRK2, more of the active enzyme the gene generates is present in their brains than in healthy brains, researchers reported last week (July 25) in Science Translational Medicine. The finding suggests that LRRK2 inhibitors could help to reduce harmful effects ofContinue reading “LRRK2 enzyme is implicated in even more Parkinson’s disease cases than originally realized, suggesting that inhibitors of the enzyme could treat more patients.”
