Mother’s Touch Supports Pup's Brain Development
A mother's presence may have immediate and long-term effects on her child's developing brain by modulating the serotonin system, suggests a study of rat moms and their pups published in eNeuro. The research provides a potential mechanism by which separating a child from his or her mother early in life could derail development.
By wirelessly recording the brain activity of rat pups during interaction with their mother, Catia Teixeira and colleagues provide evidence for a direct connection between maternal care and the neurotransmitter serotonin — two factors known to be crucially involved in brain development. The researchers demonstrate that a mother’s presence in the nest increases activity in the pups’ prefrontal cortex, a slowly developing brain region rich in serotonin receptors. Blocking these receptors counteracted the effect, while treating isolated pups with the selective-serotonin-reuptake-inhibitor fluoxetine increased prefrontal cortex activity similarly to that observed in the mother’s presence. These results implicate maternal contact and the serotonin system as important regulators of neuronal activity in the developing brain.

Investigators Receive Funding to Probe Genetic Protection in Alzheimer's
Efrat Levy, PhD, Paul Mathews, PhD (Center for Dementia Research), and Donald Wilson, PhD (Emotional Brain Institute) are Co-Principal Investigators on a large RF1 NIA grant titled “Neuronal protective apolipoprotein E2-mediated endocytic and exocytic pathways”. This application was in response to a request for applications from the NIA designed to fill in the significant gap in the field's understanding of why the apolipoprotein E2 allele is protective against Alzheimer's disease. The success of this grant was made possible by preliminary findings by Kathy Peng during her graduate studies, by the efforts of Brett East and Gloria Fleming, and through NKI’s mouse resources, supported in part by the efforts of Monika Pawlik and by Kathleen Shannon and the rest of the facility staff.
