A new study in macaque monkeys has shed light on which parts of the brain support credit assignment processes (how the brain links outcomes with its decisions) and, for the first time, how low-intensity transcranial ultrasound stimulation (TUS) can modulate both brain activity and behaviours related to these decision-making and learning processes. While currently developed in an...
by Amy King, University of Plymouth Credit: Pixabay/CC0 Public Domain Imagine passing an exam, and thinking your success was down to the socks you wore or the number of biscuits you’d eaten, rather than the hours of study you’d put in. This is an issue of ‘credit assignment’, where a person or animal attributes the...
NOVEMBER 16TH, 2021 CONN HASTINGS RADIOLOGY, REHAB At Harvard University a team of scientists and engineers developed an exosuit that uses ultrasound to measure muscle activity. The capability allows for rapid calibration of the suit for users’ needs. The soft wearable device continuously assists when walking or running, reducing the energy required to perform these tasks, which...
Pauline Anderson A new noninvasive procedure is safe and effective for treating patients with mild Alzheimer’s disease (AD), new research suggests. Clinicians monitor a trial patient with AD undergoing low-intensity focused ultrasound. The approach uses MRI-guided low-intensity focused ultrasound (FUS) and injected microbubbles to temporarily open the blood-brain barrier (BBB). In a small group of patients, the...
By Ben Coxworth September 22, 2021 One of the “micro-robotic-swimmers,” groups of which may someday be used for targeted drug delivery Cornell University Although many scientists have been working on microscopic “robots” that could deliver drugs to specific locations within the body, one challenge remains – powering the things without the use of bulky onboard...
(HealthDay)—A new ulcerative colitis intestinal ultrasound (UC-IUS) index shows strong correlation with endoscopy for detection of disease activity, according to a study published in the August issue of the Journal of Crohn’s and Colitis. Steven Bots, M.D., from the Amsterdam University Medical Center, and colleagues developed an ultrasonographic activity index using endoscopy as the reference standard (evaluation of 207 colonic...
UNIVERSITY OF CALIFORNIA – SAN DIEGO Bioengineers at the University of California San Diego have developed cancer immunotherapy that pairs ultrasound with cancer-killing immune cells to destroy malignant tumors while sparing normal tissue. The new experimental therapy significantly slowed down the growth of solid cancerous tumors in mice. The team, led by the labs of...
by Zach Winn, Massachusetts Institute of Technology Credit: CC0 Public Domain It can be difficult to get drugs to disease sites along the gastrointestinal tract, which spans the mouth, esophagus, stomach, small and large intestine, and anus. Invasive treatments can take hours as patients wait for adequate amounts of drugs to be absorbed in the right...
