Visual-auditory integration

This research project explored how visual and auditory interactions occur at the cognitive level, focusing on cross-modal learning. Using an animal model, the study investigated where and how auditory signals are transformed into visuo-spatial information for navigation. Subjects were trained with spatial information from an ultrasonic "Bat Ear" device. Researchers used immunohistochemical methods to examine neural activation during training and visual deprivation. Electrode arrays recorded activities in the auditory and visual cortices, hippocampus, and perirhinal cortex. By analysing these neural structures, the study gained understandings on how memory aids in learning spatial information from auditory signals for cross-modal learning.
