“Emotional arousal can produce lasting, vivid memories for emotional experiences, but little is known about whether emotion can prospectively enhance memory formation for temporally distant information. One mechanism that may support prospective memory enhancements is the carry-over of emotional brain states that influence subsequent neutral experiences. Here (the authors) found that neutral stimuli encountered by … Continue reading

Cognitive reserve is thought to prevent cognitive decline and delay neurodegeneration. Recent data suggest that lifelong bilingualism may act through cognitive reserve to delay the onset of dementia by ∼4.5 y. The authors studied brain metabolism, a direct index of synaptic function and density, and neural connectivity to shed light … Continue reading

Intestinal microbiota influence neurodevelopment, modulate behavior, and contribute to neurological disorders. However, a functional link between gut bacteria and neurodegenerative diseases remains unexplored. Synucleinopathies are characterized by aggregation of the protein α-synuclein, often resulting in motor dysfunction as exemplified by Parkinson’s disease. Using mice … Continue reading
