UCLA and Stanford researchers pinpoint origin of sighing reflex in the brain

Researchers now have a better understanding of how the brain triggers sighing, which is vital to lung function.

Scientists, including UCLA’s Jack Feldman (department of Neurobiology in the David Geffen School of Medicine at UCLA and a member of the UCLA Brain Research Institute), have pinpointed two tiny clusters of neurons that are responsible for transforming normal breaths into sighs, which could one day allow physicians to treat patients who cannot breathe deeply on their own.

Anti-bullying program focused on bystanders helps the students who need it the most

Programs meant to reduce bullying in primary and secondary schools are often ineffective. However, after studying more than 7,000 students in 77 elementary schools in Finland, Jaana Juvonen (department of Psychology) has found one that works very well and greatly benefited the mental health of sixth-graders who experienced the most bullying. This program has also significantly improved their self-esteem and reduced signs of depression.

Research conducted by Andrew Leuchter (Semel Institute for Neuroscience and Human Behavior, department of Psychiatry and Biobehavioral Science) and David Geffen School of Medicine’s  Ian Cook (department of Psychiatry and Biobehavioral Sciences) and Christopher DeGiogio (department of Neurology) is currently underway to figure out the effectiveness of the NeuroSigma Inc. electric patch, a box about the size of a deck of cards. Patients can use it to self-administer trigeminal nerve stimulation, or TNS. The therapy has been proven to significantly reduce symptoms in veterans with PTSD and major depressive disorders.

UCLA scientists create graphene barrier to precisely control molecules for making nanoelectronics

Paul Weiss (California Nanosystems Institute, department of chemistry and biochemistry) and a team of scientists developed a technique to precisely control molecules for making nanelectronics. This technique would make it much more efficient to build nanoelectronic and nanobioelectronic devices that could measure brain cell and circuit function in real time. Neurosensors that could measure brain cell and circuit function immediately could provide further insight into diseases like depression and provide further support to the Depression Grand Challenge.
