Physiologic studies have demonstrated that, in general, swaddling decreases startling, 301 increases sleep duration, and decreases spontaneous awakenings.310 Swaddling also decreases arousability (ie, increases cortical arousal thresholds) to a nasal pulsatile air - jet stimulus, especially in infants who are easily arousable when not swaddled but less so in infants who have high arousal thresholds when not swaddled.301 One study found decreased arousability in infants at 3 months of age who were not usually swaddled and then were swaddled but found no effect on arousability in routinely swaddled infants.301 In contrast, another group of investigators showed decreased arousal thresholds310 and increases in autonomic (subcortical) responses311 to an auditory stimulus when swaddled.

«It's difficult to say at the moment,» says Diane Lazard, «but the idea is also to be able to spot in advance the people who will have a propensity for the written stimulus and to offer them active means for remaining with orality, particularly with auditory prostheses and speech therapy used much earlier than is currently practised.»

Auditory stimuli (mono, 44,100 Hz sampling rate, 16 bits per sample) were delivered at a comfortable volume through circumaural headphones (with foam earplugs inserted inside the MRI scanner).
They do not bark in response to auditory stimuli like dogs with normal hearing, but they may bark at visual stimuli or at sounds that they can still hear if they are not fully deaf.
To acclimatize the animals to the auditory stimuli, music and voice recordings, similar to those used in the experimental phase, were played during the last 10 min of the acclimation phase at approximately 5 dB above the background noise level.
