Have you heard? Susan Shore and Ross Maddox will present their research in this Science Café.
When ears aren't enough: how your eyes help you listen
We live in a world of many sights and sounds--sometimes too many. In noisy places where it's hard to hear, we often rely on what we're seeing to help us listen. We'll talk about some of the ways scientists study this "audio-visual integration," and how the results of those studies might be leveraged to improve communication in real world settings.
Why are my ears ringing? Multisensory systems contribute to tinnitus
Fifty million people in the United States suffer from some degree of tinnitus, commonly referred to as ‘ringing in the ear’. Scientists generally agree that tinnitus is generated in the brain, through ‘maladaptive neuronal plasticity’ in response to damage of the cochlea. Dr. Susan Shore, a professor of neuroscience in the department of Otolaryngology at the University of Michigan has spent the last decade studying the mechanisms underlying tinnitus generation. Her lab discovered that ‘touch’-sensitive neurons in the auditory part of the brain become hyperactive and synchronize with each other in animals that develop tinnitus. Calming these neurons down with specially-timed multisensory stimulation can reduce tinnitus in guinea pigs and humans.
UCSD scientists Drew Walker and Megan Bardolph will discuss the science underlying how our perceptions and beliefs shape our mental models of the world
Scientists Leslie Carver and Eric Courchesne will delve into science's current understanding about autism. Leslie will explore social reward processing in those with ASD, and Eric will explain why the constant reported "breakthroughs" haven't seemed to make a real difference yet.
Join UCSD researchers Erica Heinrich, Michael Tift, Esteban Moy and Naomi Deacon as they discuss the genetic and physiological adaptations in human populations living more than 14,000 feet above sea level in the Tibetan and Peruvian highlands, mammals that experience low oxygen while diving at sea and during sleep apnea events on land, and laboratory research in animal models that aims to better understand system-wide low oxygen tolerance.
