Auditory comprehension of language in young children: Neural networks identified with fMRI

Ahmad, Z., Balsamo, L. M., Sachs, B. C., Xu, B., Gaillard, W. D.·2003·Neurology

Abstract

OBJECTIVE: The organization of neuronal systems that process language in young children is poorly understood. The authors used fMRI to identify brain regions underlying auditory comprehension in healthy young children. METHODS: Fifteen right-handed children (mean age 6.8 years) underwent fMRI at 1.5-T using blood oxygen level dependent echoplanar imaging. They listened to stories with a reverse speech control condition. Group data were analyzed with statistical parametric mapping. Individual subject data were analyzed with a region of interest approach based on t-maps. An asymmetry index (AI = [(L-R)/(L+R)]) was calculated for each region. RESULTS: Group analysis showed significant activation in the left middle temporal gyrus (Brodmann area [BA] 21) and left superior temporal gyrus (BA 22) along the superior temporal sulcus extending back to the angular gyrus (BA 39). Individual maps showed lateralized activation in temporal regions (AI > 0.49 +/- 0.39). There was minimal activation in the frontal lobe. There were no significant correlations between age and regional AI. CONCLUSION: Networks for auditory language processing are regionally localized and lateralized by age 5. These data may provide a means to interpret language fMRI studies performed in preparation for brain surgery, and may be employed to investigate the effect of chronic disease states, such as epilepsy, on language organization during critical periods for plasticity.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A temporal-parietal network including middle temporal gyrus (BA21), superior temporal gyrus (BA22), and angular gyrus (BA39) is important in auditory language processing in children.

    “A network in the temporal-parietal cortex consisting of the middle temporal gyrus (BA 21), the superior temporal gyrus (BA 22) and the angular gyrus (BA 39) has been shown to be important in processes related to auditory language processing in children (Ahmad et al., 2003).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
