Parsing Autism Spectrum Heterogeneity Through fMRI
Researchers from UNC and international partners published a cross‑species fMRI study in Nature Neuroscience that uncovers two principal dysconnectivity signatures in autism. The signatures emerged from analyses of 20 mouse models of autism risk and were each tied to distinct molecular pathways—one involving synaptic signaling, the other immune system processes. Parallel functional connectivity patterns were observed in autistic human participants, demonstrating translational relevance. The findings provide a biologically grounded framework for phenotyping the heterogeneous spectrum of autism.
