Infantile autism and the temporal lobe of the brain.
Autism traits line up with bilateral temporal-lobe dysfunction, so treat sound and face cues like sensory inputs, not social snubs.
01Research in Context
What this study did
The authors pulled together animal and human brain studies. They asked: do autism traits look like damage to both temporal lobes?
They looked at language delays, sound sensitivity, face memory, and tantrums. They mapped each trait to a spot in the temporal lobe.
What they found
They say the map fits. Kids who later get autism act like monkeys with scarred temporal lobes.
The review claims the root problem is not bad parenting or slow learning. It is hidden brain disconnection.
How this fits with other research
Demello et al. (1992) moved the talk from brain to checklists. Their DSM study shows the field shifted from "why" to "how to diagnose."
Brosnan et al. (2010) kept the brain angle but added hormones. They link strong systemizing and high testosterone to the same kids, widening the 1981 model.
Aragon-Guevara et al. (2025) warn the public story is now broken. Three out of four viral TikTok clips about autism are wrong, so the old brain model is buried under myths.
Why it matters
When a child ignores your voice but hears the faucet drip across the room, think temporal lobe, not defiance. Use clear visuals, reduce background noise, and check hearing first. The 1981 paper reminds you that some "behavioral" problems are wiring issues, not skill deficits.

03Original abstract
Studies are reviewed that support the hypothesis that infantile autism results from a neuropathology of the temporal lobes of the brain. First, there are parallels between symptoms noted in autism and those found in the Kluver-Bucy and amnesic syndromes. Second, there is a similarity between developmental dysphasia and autism. Third, the formation of cross-modal associations may be deficient in autistic children, a symptom resembling aspects of Geschwind's disconnection syndromes. Finally, a large number of organic factors have been associated with the development of autism, some of these having specific implications for temporal lobe involvement. It is concluded that the main autistic symptoms are most consistent with a neurological model involving bilateral dysfunction of the temporal lobes. Individual differences in the extent of bilateral involvement and/or other coexistent neuropathologies could contribute to the heterogeneity of the autistic population.
