The Teenage Brain: Public Perceptions of Neurocognitive Development during Adolescence.

ABSTRACT: Over the past decade, important insights have been obtained into the neurocognitive development during adolescence. To better understand how these neuroscientific insights impact the real world, we investigated how neuroscience has shaped public perceptions of the "teenage brain" and if these perceptions influence adolescent behavior. When asking to generate free associations with the word "teenage brain," adolescents ( n = 363, Mage = 14.47 years) and parents ( n = 164, Mage = 47.16 years) more often mention undesirable behaviors (e.g., "irresponsible") than desirable behaviors (e.g., "creative"). Despite these dominantly negative associations, priming adolescents with positively versus negatively framed statements about adolescent brain development did not influence their subsequent risk-taking, impulsivity, and performance on response-to-failure tasks. However, we did find a more nuanced effect, related to how much adolescents agreed with the negative versus positive priming statements: Adolescents' negative beliefs about adolescent brain development reinforced negative behaviors by increased risk-taking behaviors, and adolescents' positive beliefs reinforced positive behaviors by using positive strategies to cope with academic setbacks. The current findings underline the impact of views that build up over time and that these are not easily influenced by a one-time instance of information but rather reinforce the impact of new information. To prevent negative perceptions of the teenage brain from becoming self-fulfilling prophecies, it is important that communication about adolescent neurocognitive development is framed in a more balanced way. Neuroscientists need to be more aware of how their research impacts the real world, before we are fully ready for "real-world neuroscience."

Project description:Targeting mitochondrial ion homeostasis using Kaempferol, a mitochondrial Ca2+ uniporter channel activator, improves energy metabolism and behavior soon after a traumatic brain injury (TBI) in developing rats. Because of broad TBI pathophysiology and brain mitochondrial heterogeneity, Kaempferol-mediated early-stage behavioral and brain metabolic benefits may accrue from diverse sources within the brain. We hypothesized that Kaempferol influences TBI outcome by differentially impacting the neural, vascular, and synaptic/axonal compartments. After TBI at early development (P31), functional magnetic resonance imaging and diffusion tensor imaging (DTI) were applied to determine imaging outcomes at adolescence (2 months post-injury). Vehicle and Kaempferol treatments were made at 1, 24, and 48 h post-TBI, and their effects were assessed at adolescence. A significant increase in neural connectivity was observed after Kaempferol treatment as assessed by the spatial extent and strength of the somatosensory cortical and hippocampal resting-state functional connectivity (RSFC) networks. However, no significant RSFC changes were observed in the thalamus. DTI measures of fractional anisotropy (FA) and apparent diffusion coefficient, representing synaptic/axonal and microstructural integrity, showed significant improvements after Kaempferol treatment, with highest changes in the frontal and parietal cortices and hippocampus. Kaempferol treatment also increased corpus callosal FA, indicating measurable improvement in the interhemispheric structural connectivity. TBI prognosis was significantly altered at adolescence by early Kaempferol treatment, with improved neural connectivity, neurovascular coupling, and parenchymal microstructure in select brain regions. However, Kaempferol failed to improve vasomotive function across the whole brain, as measured by cerebrovascular reactivity. The differential effects of Kaempferol treatment on various brain functional compartments support diverse cellular-level mitochondrial functional outcomes in vivo.
