“…The 2-3 Hz range emerging in the present study would endorse a prosodic/word level rather than syllabic frame. Furthermore, these slow oscillations may represent an essentially subcortical template, potentially supported even by brainstem pattern generators (Barlow et al, 2010), on which detailed gestural patterning can be interwoven at the cortical level.…”

Human speech features rhythmicity that frames distinctive, fine-grained speech patterns. Speech can thus be counted among rhythmic motor behaviors that generally manifest characteristic spontaneous rates. However, the critical neural evidence for tuning of articulatory control to a spontaneous rate of speech has not been uncovered. The present study examined the spontaneous rhythmicity in speech production and its relationship to cortex-muscle neurocommunication, which is essential for speech control. Our MEG results show that, during articulation, coherent oscillatory coupling between the mouth sensorimotor cortex and the mouth muscles is strongest at the frequency of spontaneous rhythmicity of speech at 2-3 Hz, which is also the typical rate of word production. Corticomuscular coherence, a measure of efficient cortex-muscle neurocommunication, thus reveals behaviorally relevant oscillatory tuning for spoken language.

“…Most of these sounds do not excite the vocal tract’s full resonance yet and phonation does not involve a distinct systematic mouth opening [17]. These very first vocalisations have also been discussed to be CPG-generated behaviour [60]. Basic understanding of the CPG circuitry for mouth movements and respiration suggests multiple foci in the brain stem [61].…”

Purpose of ReviewSubstantial research exists focusing on the various aspects and domains of early human development. However, there is a clear blind spot in early postnatal development when dealing with neurodevelopmental disorders, especially those that manifest themselves clinically only in late infancy or even in childhood.Recent FindingsThis early developmental period may represent an important timeframe to study these disorders but has historically received far less research attention. We believe that only a comprehensive interdisciplinary approach will enable us to detect and delineate specific parameters for specific neurodevelopmental disorders at a very early age to improve early detection/diagnosis, enable prospective studies and eventually facilitate randomised trials of early intervention.SummaryIn this article, we propose a dynamic framework for characterising neurofunctional biomarkers associated with specific disorders in the development of infants and children. We have named this automated detection ‘Fingerprint Model’, suggesting one possible approach to accurately and early identify neurodevelopmental disorders.

“…For example, the Ruffini ending is most responsive to slow indentations of the lip and encode position, whereas the Meissner corpuscle is most responsive to rapid changes in skin indentation and pressure (e.g., vibration). Collectively, these mechanoreceptors make it possible for the infant to appreciate a wide range of oral experiences, some of which are presumed to be soothing (e.g., light touch from a caretaker’s finger, stiffness of a pacifier, infant’s fingers, mother’s breast) whereas other unexpected orosensory experiences may lead to maladaptive oral aversion (e.g., orotracheal intubation, nasogastric feeding tube, ventilator, tape on the skin) at a critical period of brain development for ororhythmic pattern formation (Barlow, 2009a; Barlow et al, 2010; Shiao et al, 1995). …”

The precocial nature of orofacial sensorimotor control underscores the biological importance of establishing ororythmic activity in human infants. The purpose of this study was to assess the effects of comparable doses of three forms of orosensory experience, including a low-velocity spectrally reduced orocutaneous stimulus (NT1), a high-velocity broad spectrum orocutaneous stimulus (NT2), and a SHAM stimulus consisting of a blind pacifier. Each orosensory experience condition was paired with gavage feedings 3x/day for 10 days in the neonatal intensive care unit (NICU). Four groups of preterm infants (N=214), including those with respiratory distress syndrome (RDS), chronic lung disease (CLD), infants of diabetic mothers (IDM), and healthy controls (HI) were randomized to the type of orosensory condition. Mixed modeling, adjusted for gender, gestational age, postmenstrual age, and birth weight, demonstrated the most significant gains in non-nutritive suck (NNS) development among CLD infants who were treated with the NT2 stimulus, with smaller gains realized among RDS and IDM infants. The broader spectrum of the NT2 stimulus maps closely to known response properties of mechanoreceptors in lip, tongue, and oral mucosa and is more effective in promoting NNS development among preterm infants with impaired oromotor function compared to the low-velocity, spectrally reduced NT1 orosensory stimulus.
