OndesDès le ventre de la mère, la perception auditive est influencée par ce qu'entend le fœtus pendant les neuf mois de grossesse. Il réagit aux sons environnants, apprenant même l'accent maternel, qui influence à son tour les cris du nouveau-né après la naissance.

The organization of neural integration windows in the human auditory cortex

Temporal integration is fundamental to sensory processing. In the auditory domain, the brain must integrate across hierarchically organized structures (e.g., phonemes, syllables, and words) spanning tens to hundreds of milliseconds to derive meaning from sound. Yet surprisingly little is known about the specific timescales over which different regions of the human auditory cortex integrate information, in part due to their complex, nonlinear tuning for natural sounds.

Plasticity of temporal integration in ferret auditory cortex

Retrieving meaning from complex auditory stimuli requires flexible binding in time of auditory features at different timescales. Recent reports suggest that sensory perception relies on a hierarchy of auditory timescales and progressive processing of information through a hierarchy of cortical areas. Although temporal dynamics of auditory perception have been thoroughly studied, little is known about the plasticity of temporal integration windows (or timescales) in the auditory cortex.
