From: The normal environment delays the development of multisensory integration
Exemplars illustrate a gradual development of multisensory integration capabilities, and receptive field register, during the cross-modal exposure period. Shown are 3 typical neurons recorded from the same noise-reared animal after being exposed to an increasing number of cross-modal stimuli. Below each schematic are the numbers of exposures (5,400 trials ≈ 9 hours of experience; 21,600 ≈ 36 hours; 39,600 ≈ 66 hours) provided prior to the tests generating these data. Conventions are the same as in Figs 2 and 3. Left: The RFs and visual and auditory spatial response profiles increased their overlap with increased cross-modal exposure. Middle: rasters and summary graphs show progressive increases in multisensory enhancement with increasing cross-modal exposure. Right: Summary of the changes in responsiveness and ME. *P < 0.05. Conventions are the same as in previous figures.
