>Each of these dimensions was predicted by unique abnormalities of brain networks,” Satterthwaire explained. “However, all dimensions were marked by abnormally high levels of connectivity between the default mode network and fronto-parietal network, two brain regions that usually become increasingly distinct as the brain matures. This loss of normal brain network segregation supports the hypothesis that many psychiatric illnesses may be disorders of brain development.”
I wonder if that points to failures of the synaptic pruning that's supposed to happen in preschool-to-primary-school age kids.
- ss2003 8y agoSure, but synaptic pruning happens at all ages. After all that's how we learn anything and forget unimportant experiences. It would be interesting if one could strengthen certain interconntions while weakening the mental illness causing ones.
- petra 8y agoMeditation and possible some states of enlightenment(fully quiet mind), are about reducing activity in the default-mode-network(DMN). Psychologically this is seen as a reduction/loss of the sense of self(or more exactly stopping self-referential thoughts) On the other hand, a common association[1] with several mental illnesses, is rumination("repetitive, self-directed thought") - which actually fits the current study. One wonders if specific mental illness cause rumination and why ? or is it backwards ?
