Hall's Neural Imprint Syndrome (HNIS): A Synthesis of Emerging Evidence for Cellular and Bioelectrical Mechanisms

This paper synthesises emerging evidence relevant to Hall's Neural Imprint Syndrome (HNIS), also known as Harmonic Neurodivergent Imprinting Syndrome: an independently developed theoretical framework proposing that neurodivergent nervous systems encode formative and traumatic experience through mirror neuron imprinting at a cellular and bioelectrical level. Drawing on five lines of recent research (predictive coding and trauma; bioelectrical cellular memory; the biological "third state"; theta-burst stimulation in autistic children; and mirror neuron research in autism), it argues that HNIS proposes a candidate mechanism for the rigidity that predictive coding models of trauma describe but leave open. HNIS is offered as a hypothesis for testing, not as an established clinical entity.
