New non-invasive technique controls size of molecules penetrating the blood-brain barrier

August 14, 2014 4:14 pm | by EurekAlert! | News | Comments

A new technique developed by Elisa Konofagou, professor of biomedical engineering and radiology at Columbia Engineering, has demonstrated for the first time that the size of molecules penetrating the blood-brain barrier (BBB) can be controlled using acoustic pressure—the pressure of an ultrasound beam—to let specific molecules through.

Bypass commands from the brain to legs through a computer

August 14, 2014 10:08 am | by EurekAlert! | News | Comments

Gait disturbance in individuals with spinal cord injury is attributed to the interruption of neural pathways from brain to the spinal locomotor center, whereas neural circuits locate below and above the lesion maintain most of their functions. An artificial connection that bridges the lost pathway and connects brain to spinal circuits has potential to ameliorate the functional loss.

Hijacking the Brain's Blood Supply: Tumor Discovery Could Aid Treatment

August 12, 2014 11:21 am | by University of Michigan Health System | News | Comments

Dangerous brain tumors hijack the brain's existing blood supply throughout their progression, by growing only within narrow potential spaces between and along the brain's thousands of small blood vessels, new research shows for the first time. The findings contradict the concept that brain tumors need to grow their own blood vessels to keep themselves growing ...

Expert Panel Concludes Neurostimulation Can Be Life-Changing Therapy for Chronic Pain

August 12, 2014 11:07 am | by Johns Hopkins Medicine | News | Comments

Chronic pain, which persists despite the fact that an injury has healed, can last for many months or years and may affect up to 15 percent of the adult population at any point in time. While it is a condition in its own right, it can be a component of other conditions. Neurostimulation, which involves stimulating pain-sensing nerves to convert painful sensations into nonpainful ones, offers ...
