“”Ultrasound has great potential for bringing unprecedented resolution to the growing trend of mapping the human brain’s connectivity,” said William “Jamie” Tyler, an assistant professor at the Virginia Tech Carilion Research Institute, who led the study. “So we decided to look at the effects of ultrasound on the region of the brain responsible for processing tactile sensory inputs.””
“”It opens the door to understanding opioid related drugs for treating pain and mood disorders, among others,” said lead author Dr. Gustavo Fenalti, a postdoctoral fellow in the laboratory of Professor Raymond C. Stevens of TSRI’s Department of Integrative Structural and Computational Biology.
“This discovery has helped us decipher a 40-year-old mystery about sodium’s control of opioid receptors,” said Stevens, who was senior author of the paper with UNC pharmacologist Professor Bryan Roth. “It is amazing how sodium sits right in the middle of the receptor as a co-factor or allosteric modulator.””
“The research is published online today in the Journal of Behavioral and Developmental Pediatrics. It was led by Robin Hansen, director of the Center for Excellence in Developmental Disabilities at the MIND Institute and chief of the Division of Developmental Behavioral Pediatrics in the UC Davis School of Medicine.
“In our Northern California study population, it does not appear that families use complementary and alternative treatments due to the lack of availability of conventional services, as has been suggested by other research,” Hansen said. “Rather, they use the treatments in addition to conventional approaches.””
“In the following interview, Dr. Freberg offers a rare glimpse of her struggle to gain the education required to become an accomplished professional psychologist. Dr. Freberg also discusses her range of experiences during a typical workday now, and when she was a young mother juggling all the demands of career and home life. The span of her accomplishments and assortment of outreach to wide variety of populations is a central component of this highly informative interview.”
“”Sleep is the price the brain must pay for learning and memory,” says Dr. Giulio Tononi, of the UW Center for Sleep and Consciousness. “During wake, learning strengthens the synaptic connections throughout the brain, increasing the need for energy and saturating the brain with new information. Sleep allows the brain to reset, helping integrate, newly learned material with consolidated memories, so the brain can begin anew the next day. “
Tononi and his co-author Dr. Chiara Cirelli, both professors of psychiatry, explain their hypothesis in a review article in today’s issue of the journal Neuron. Their laboratory studies sleep and consciousness in animals ranging from fruit flies to humans; SHY takes into account evidence from molecular, electrophysiological and behavioral studies, as well as from computer simulations. “Synaptic homeostasis” refers to the brain’s ability to maintain a balance in the strength of connections within its nerve cells.”
“Such body language, known as a “dominance threat display” and labeled as “triumph” in other studies, was observed in winners of Olympic and Paralympic judo matches. It appears to be innate and stems from an evolutionary need to establish order and hierarchy in society, said San Francisco State University Professor of Psychology David Matsumoto, who co-authored the study with Hyisung Hwang, an adjunct faculty member in psychology at SF State.”
