Scientists reverse core symptom of schizophrenia in adult mice

Neuronal branches in SETD1A deficient mice are shorter and stunted. Switching off another gene, LSD1, nullifies the harmful effects of SETD1A on neuron and axon growth. After inhibiting LSD1, SETD1A deficient mice showed improved memory and axon growth. Inhibiting LSD1 not only acted on memory deficits linked to schizophrenia but also acted on the underlying molecular mechanisms associated with axonal growth.

Parenting stress may affect mother’s and child’s ability to tune in to each other

Mothers who reported higher levels of parental stress had less synchrony in brain activity with their young children than moms who were more stress-free. The findings shed new light on how parental stress can impact the mother-child relationship on a day-to-day basis.
