We investigate the utility of near-infrared spectroscopy (NIRS) as an alternative technique for studying infant speech processing. NIRS is an optical imaging technology that uses relative changes in total hemoglobin concentration and oxygenation as an indicator of neural activation. Procedurally, NIRS has the advantage over more common methods (e.g., fMRI) in that it can be used to study the neural responses of behaviorally active infants. Older infants (aged 6–9 months) were allowed to sit on… 

Optical brain imaging reveals general auditory and language-specific processing in early infant development.

This study is the first to discover a significantly higher sensitivity to L1 in 4 month-olds and reveals a neural precursor of the functional specialization for the higher cognitive network.

In this review of empirical findings from human infants, ranging in age from birth to 12 months of age, a number of interpretive concerns are raised about what can be concluded from NIRS data, and inconsistencies across studies are highlighted.

Cerebral hemodynamics in newborn infants exposed to speech sounds: A whole‐head optical topography study

A whole‐head optode cap for 72‐channel optical topography and visualized the spatiotemporal hemodynamics in the brains of 17 Japanese newborns showed that the left temporal‐parietal region was significantly more active for Japanese FW than Japanese BW or English FW, while no significant difference between FW and BW was shown for English.

Hemodynamic responses to speech and music in preverbal infants

A new way to conceptualize the variable cortical blood flow patterns that are frequently observed across infants and stimuli is highlighted, with hemodynamic response volumes potentially serving as an early indicator of developmental changes in auditory-processing sensitivity.

erebral lateralization and early speech acquisition : A developmental cenario

During the past ten years, research using Near-infrared Spectroscopy (NIRS) to study the developing brain has provided groundbreaking evidence of brain functions in infants. This paper presents a



Assessing infants' cortical response to speech using near-infrared spectroscopy

Brain imaging in awake infants by near-infrared optical topography

Functional brain imaging of awake infants viewing visual stimuli by means of multichannel near-infrared spectroscopy shows event-related increases in oxyhemoglobin were evident in localized areas of the occipital cortex of infants aged 2–4 months in response to a brief presentation of a checkerboard pattern reversal.

Using near-infrared spectroscopy to assess neural activation during object processing in infants.

Examination of the extent to which increased neural activation, as measured by NIRS, could be observed in two neural areas known to be involved in object processing, the primary visual cortex and the inferior temporal cortex, during an object processing task suggests these neural areas support object processing in the young infant.

Hemodynamic response to featural changes in the occipital and inferior temporal cortex in infants: a preliminary methodological exploration.

The present research examined the extent to which near-infrared spectroscopy (NIRS) could be used to assess the relation between object processing and brain functioning in infants and the viability of using NIRS to study brain-behavior relations in infants.

Activation of Olfactory Cortex in Newborn Infants After Odor Stimulation: A Functional Near-Infrared Spectroscopy Study

It is concluded that monitoring Hb changes by NIRS can be valuable in assessing olfactory responsiveness in infants and that the magnitude of the [Hb O2] increase over the illuminated region during colostrum exposure was inversely related to postnatal age.

Assessment of Infant Brain Development With Frequency-Domain Near-Infrared Spectroscopy

This is the first report to demonstrate quantitative monitoring of infant brain development with frequency-domain near-infrared spectroscopy (FD-NIRS), and new information includes the relatively constant tissue oxygenation with age and location, suggesting a tight control between local oxygen delivery and consumption in healthy infants during brain development.
