Saccadometry and LATER model shed light on brain plasticity in aging

As frequency of falls increases in older adults, understanding how motor training programs counteract motor decline is a challenging issue. This study examined ocular saccades to test the effects of fall prevention (FP) on central motor control of older fallers. Saccades were recorded using a saccadometer in twelve participants aged 64–91 years before and after 2.5-month training in FP. We performed LATER analysis enabling us to examine the changes in motor control. FP decreased saccade latency and increased left-right symmetry of motor responses. LATER analysis showed that FP modulated decisional thresholds extending our knowledge of FP influence on motor control.
