“…Specifically, the inferior colliculus has been identified as the dominant neural generator underlying 80 Hz ASSRs (Giraud & Lorenzi, ). Alternatively, MEG studies have reported mainly cortical contributions to ASSRs, regardless of the modulation frequency (Ross, Borgmann, Draganova, Roberts, & Pantev, ; Schoonhoven, Boden, Verbunt, & de Munck, ; Tang, Brock, & Johnson, ). Given that MEG is relatively insensitive in recording sources with a radial orientation and sources that are deeply located in the brain, these findings were probably dominated by a (weak) cortical 80 Hz ASSR source.…”

Developmental dyslexia is defined as a learning disability, characterized by severe and persistent difficulties with reading and/or spelling, despite adequate intelligence and instruction (Peterson & Pennington, 2012). To date, it is widely accepted that dyslexia is associated with a specific cognitive deficit in phonological processing, that is, in the representation, storage, and retrieval of speech sounds (Vellutino,

“…The left and right auditory cortices are specialized to process acoustic features at different time scales, such as those conveyed by speech, simultaneously. Converging evidence suggests that slow, low-frequency temporal features (~200 ms; 3–7 Hz; syllables) are biased to right hemisphere auditory cortex, whereas fast, high-frequency temporal features (~20–50 ms; 20–50 Hz; phonemes) are biased leftward 1 2 3 4 . Parsing of a speech stream into finer units of information is hypothesized to occur through phase-locking of left-lateralized gamma oscillations and right-lateralized theta oscillations 5 6 7 .…”

Speech signals contain information in hierarchical time scales, ranging from short-duration (e.g., phonemes) to long-duration cues (e.g., syllables, prosody). A theoretical framework to understand how the brain processes this hierarchy suggests that hemispheric lateralization enables specialized tracking of acoustic cues at different time scales, with the left and right hemispheres sampling at short (25 ms; 40 Hz) and long (200 ms; 5 Hz) periods, respectively. In adults, both speech-evoked and endogenous cortical rhythms are asymmetrical: low-frequency rhythms predominate in right auditory cortex, and high-frequency rhythms in left auditory cortex. It is unknown, however, whether endogenous resting state oscillations are similarly lateralized in children. We investigated cortical oscillations in children (3–5 years; N = 65) at rest and tested our hypotheses that this temporal asymmetry is evident early in life and facilitates recognition of speech in noise. We found a systematic pattern of increasing leftward asymmetry for higher frequency oscillations; this pattern was more pronounced in children who better perceived words in noise. The observed connection between left-biased cortical oscillations in phoneme-relevant frequencies and speech-in-noise perception suggests hemispheric specialization of endogenous oscillatory activity may support speech processing in challenging listening environments, and that this infrastructure is present during early childhood.

“…As MEG mainly records cortical activities and not subcortical activities, it has been suggested that the maturation of cortical regions involved in the processing of 40 Hz modulations develop over age (28). This has also been observed more recently when comparing AMFR as measured with MEG in children between 3 to 5 years and adults (33). Listeners were presented with amplitude modulated noise at rates ranging from 1 to 80 Hz.…”

Human infants are able to acquire quickly a language by “simple” exposure to speech. This remarkable capacity is rather surprising knowing that the auditory cortices are still developing until the end of adolescence. Many psychoacoustic studies have explored how the adult auditory system processes the acoustic components of speech, showing that slow variations in sound amplitude over time (AM) are of crucial importance for speech perception. In the present study, we investigated the processing of AM using electroencephalography (EEG) in 3- and 10-month-old awake infants, as well as in young adults. We measured the auditory brain activity following the modulation frequency of sinusoidally amplitude modulated tones at 8 and 40 Hz. Results showed that the Amplitude-Modulation Following Response (AMFR) was observable at 8 Hz at all ages, but that only adults showed reliable responses at 40 Hz. In light of the previous literature, we propose that the neural processing sources of faster AM rates may be located preponderantly in subcortical regions at younger ages, while, in adults, both cortical and subcortical sources are activated. Such neuro-developmental trajectories might underlie the processing of fine acoustic cues that are necessary for speech and language development.
