Developmental sex differences in resting state functional connectivity of amygdala sub-regions
Open accessAbstract
During adolescence, considerable social and biological changes occur that interact with functional brain maturation, some of which are sex-specific. The amygdala is one brain area that has displayed sexual dimorphism, specifically in socio-affective (superficial amygdala [SFA]), stress (centromedial amygdala [CMA]), and learning and memory (basolateral amygdala [BLA]) processing. The amygdala has also been implicated in mood and anxiety disorders which display sex-specific features, most prominently observed during adolescence. Using functional magnetic resonance imaging (fMRI), the present study examined the interaction of age and sex on resting state functional connectivity (RSFC) of amygdala sub-regions, BLA and SFA, in a sample of healthy adolescents between the ages 10 and 16 years (n = 122, 71 boys). Whole-brain, voxel-wise partial correlation analyses were conducted to determine RSFC of bilateral BLA and SFA seed regions, created using the Eickhoff-Zilles maximum probability maps based on cytoarchitectonic mapping and FMRIB's Integrated Registration and Segmentation Tool (FIRST). Monte Carlo simulation was implemented to correct for multiple comparisons (threshold of 53 contiguous voxels with a z-value ≥ 2.25). Results indicated that with increasing age, there was a corresponding decrease in RSFC between both amygdala sub-regions and parieto-occipital cortices, with a concurrent increase in RSFC with medial prefrontal cortex (mPFC). Specifically, boys and girls demonstrated increased coupling of mPFC and left and right SFA with age, respectively; however, neither sex showed increased connectivity between mPFC and BLA, which could indicate relative immaturity of fronto-limbic networks that is similar across sex. A dissociation in connectivity between BLA- and SFA-parieto-occipital RSFC emerged, in which girls had weaker negative RSFC between SFA and parieto-occipital regions and boys had weaker negative RSFC of BLA and parieto-occipital regions with increased age, both standing in contrast to adult patterns of amygdala sub-regional RSFC. The present findings suggest relative immaturity of amygdala sub-regional RSFC with parieto-occipital cortices during adolescence, with unique patterns in both sexes that may support memory and socio-affective processing in boys and girls, respectively. Understanding the underlying normative functional architecture of brain networks associated with the amygdala during adolescence may better inform future research of the neural features associated with increased risk for internalizing psychopathology.

Written from the paper’s full text.
TL;DR
This fMRI study tested whether age and sex interact in resting-state functional connectivity of basolateral and superficial amygdala subregions in 122 healthy adolescents aged 10–16. It reports sex-specific developmental shifts in amygdala coupling with parieto-occipital and medial prefrontal regions, suggesting different maturational timing for BLA- and SFA-based networks.
Key findings
- Across age, both BLA and SFA showed weaker connectivity with parieto-occipital cortices and stronger connectivity with mPFC, but the direction of change differed by sex.
- Girls showed a shift from positive to negative BLA–parieto-occipital connectivity with age, whereas boys showed the reverse, with both shifting around age 14; for SFA–parieto-occipital connectivity, boys became more negative and girls more positive with age.
- mPFC coupling was lateralized by sex: boys showed increased left SFA–left vmPFC connectivity with age, while girls showed increased right SFA–dmPFC connectivity; neither sex showed increased mPFC–BLA coupling.
- Adding puberty as a covariate did not significantly change the connectivity results (all r² ≥ 0.52, p ≤ 0.001).
Methods
- Cross-sectional sample of 122 adolescents (71 boys), ages 10–16, without current DSM-IV psychiatric disorders, significant substance use, neurological illness, or other exclusionary conditions; scanned at 3T with two resting-state fMRI runs.
- Amygdala subregion ROIs were defined by intersecting Eickhoff-Zilles maximum probability maps with FIRST-based segmentation; BLA and SFA were analyzed, while CMA was excluded because many participants had zero or very few CMA voxels (BLA mean voxel count 905.1 ± 232.4; SFA 180.8 ± 85.6; CMA 0.9 ± 2.2).
- Whole-brain voxel-wise partial correlations modeled age, sex, sex-by-age, and residual framewise displacement; Monte Carlo correction used 53 contiguous voxels at z ≥ 2.25. Post-hoc models added puberty as a covariate.
Limitations
- The paper states that the cross-sectional design cannot capture developmental change or causal effects, that CMA could not be reliably analyzed, that the puberty measure had only modest agreement with clinician or Tanner assessments, and that a supplementary motion-censoring analysis was consistent but some effects became trend-like.
- The paper also notes the lack of adult comparison data, which limits conclusions about whether the observed adolescent patterns represent immature or transitional connectivity.
- Evident from the text: the sample is healthy and restricted to ages 10–16, and the authors describe behavioral and clinical interpretations as speculative because no direct behavioral or psychopathology outcomes were tested.

What the sources say
- Supportedcites Power et al., 2012 source
The Discussion concludes that head-motion artifacts contribute substantially to resting-state functional connectivity MRI signals and produce spurious correlation patterns. The Results also show motion-related BOLD changes persisting after standard correction, supporting the stated sensitivity to head motion. (LLM, conf=0.94)
- Supportedcites Satterthwaite et al., 2012 source
The Discussion reports that in-scanner head motion influences multiple measures of functional connectivity and concludes that it affects common analyses of resting-state functional MRI data. The Conclusions section also recommends accounting for motion when comparing connectivity. (LLM, conf=0.94)
- Supportedcites Van Dijk et al., 2012 source
The Introduction states that resting-state functional connectivity MRI is sensitive to head motion, even after common preprocessing. The Discussion reports that head motion systematically affects functional connectivity estimates, supporting the reason given for careful motion correction. (LLM, conf=0.95)

The Results (Amygdala hyperconnectivity; page unavailable) report greater left-amygdala connectivity with a medial parietal region in participants with remitted MDD, but do not report increased connectivity with occipital cortex. The Methods (Cross-Correlation Analysis; page unavailable) add that the left-amygdala differences became nonsignificant after accounting for movement.

“As such, it is believed that amygdalar functioning is not down-regulated effectively by medial prefrontal cortex (mPFC) and rostral anterior cingulate cortex (rACC) during adolescence (i.e. Dual Systems Model), which can manifest as heightened emotional reactivity typical of this developmental period (Hare et al., 2008, Perlman and Pelphrey, 2011, McRae et al., 2012, Gee et al., 2013).”

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Rated major: it would touch a result — a value a result rests on, reported and recomputed p-values on opposite sides of the significance level, two passages that conflict with no sign which is right, or a cited work retracted before this paper was published.
In the paper
§ Developmental sex differences in resting state functional connectivity of amygdala sub-regions > 4. Discussion
“in which SFA RSFC is more mature in girls, while BLA RSFC is more mature in boys.”
§ Developmental sex differences in resting state functional connectivity of amygdala sub-regions > 4. Discussion > 4.1 Age-by-sex effects
“the present results support an interpretation of increased maturity of limbic-parietal-occipital networks supported by BLA in girls and SFA in boys”
Rated major: it would touch a result — a value a result rests on, reported and recomputed p-values on opposite sides of the significance level, two passages that conflict with no sign which is right, or a cited work retracted before this paper was published.
In the paper
§ Developmental sex differences in resting state functional connectivity of amygdala sub-regions > 4. Discussion
“Rather, with age, boys showed coupling between vmPFC and BLA, while girls showed coupling between dmPFC and SFA”
§ Developmental sex differences in resting state functional connectivity of amygdala sub-regions > Abstract
“neither sex showed increased connectivity between mPFC and BLA”
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.
In the paper
“FD was negatively correlated with age (r2 = −0.22, p = 0.02). Following data scrubbing, there were no sex differences in FD (i.e. FD remaining mean) (t120 = 0.27, p = 0.79), but age was still negatively correlated with FD (r2 = −0.31, p = 0.001)”

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.
A language model drew the claims from the paper on 2026-10-05, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-05 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
