Streamlining brain signals for speed and efficacy
Date:10/22/2008

LA JOLLA, CA Life exists at the edge of chaos, where small changes can have striking and unanticipated effects, and major stimuli may go unheard. But there is no space for ambiguity when the brain needs to transform head motion into precise eye, head, and body movements that rapidly stabilize our posture and gaze; otherwise, we would stumble helplessly through the world, and our vision would resemble an undecipherable blur.

In their latest study, published in the current issue of the journal Neuron, researchers at the Salk Institute for Biological Studies explain how the vestibular-ocular reflex, which keeps us and the world around us stable, achieves the accuracy it is famous for. Unlike most signals in the brain, whose transmission is frequency-dependent, signals from the vestibular system of the inner ear, which detects motion, are relayed in a linear fashion no matter how fast the neurons are firing.

"Most of what we know about signal transmission between neurons comes from studying special cortical or hippocampal neurons, but many vital functions, such as balance and breathing, are controlled by neurons in the brain stem, which, as we discovered, work very differently," says Howard Hughes Medical Institute investigator Sascha du Lac, Ph.D., an associate professor in the Systems Neurobiology Laboratory. "Pursuing the mechanisms that control neurons in the brain stem is important for developing new classes of biotherapeutic agents."

Du Lac and her team focus on a simple type of learning: How does the brain learn to stabilize an image on the retina and use eye movement to compensate for a moving head? This so-called vestibular-ocular reflex, or VOR, needs to be fast; for clear vision, head movements must be compensated for almost immediately. To achieve the necessary speed, the VOR-circuit involves only three types of neurons: sensory neurons, which detect head movement; motor neurons, directing eye muscles to relax or co
