This new insight emphasizes the importance of considering heterogeneities in public health research to understand who benefits from life satisfaction and who does not . Credit : Neuroscience News Not All Older Adults Reap Cognitive Benefits of Life Satisfaction Featured Neuroscience Psychology September 28, 2023 Summary : A new study delves into the link between life satisfaction and cognitive functioning in older adults . Surprisingly , while many studies advocate life satisfaction as a cognitive booster , this study suggests that it doesn’t benefit . everyone High life satisfaction did enhance cognitive functioning in most individuals , but it fell short for those with low socioeconomic status , in poor health , or facing psychological challenges . This granular analysis unveils the
Flexible neuron firing â known as plasticity â is related to positive learning and memory outcomes . Credit : Neuroscience News Protein p53’s Role in Autism-like Behavior and Memory Autism Featured Genetics Neuroscience September 28, 2023 Summary : Scientists have discovered a direct link between the protein p53 and autism-like behavior in mice . The researchers studied the effects of manipulating p53 levels in the mouse . hippocampus Reduced levels resulted in repetitive behavior , diminished sociability , and impaired learning , especially in male mice . This pivotal work uncovers the intricate role of p53 in neurodevelopmental disorders like . autism Key : Facts Lowered hippocampal p53 levels in mice led to repetitive behavior , decreased sociability , and hindered
Linking Age-Related Memory Decline to a Specific Brain Cell Featured Neuroscience September 28, 2023 Summary : Researchers have delved deeper into how specific interneurons in the brain affect memory as we . age In a study focusing on the hippocampus , they found that reducing the number of somatostatin-positive interneurons led to cognitive deficits resembling aging . The mice with decreased interneurons showed signs of impaired memory , similar to naturally aged . mice This breakthrough provides a new avenue to investigate potential treatments for age-related memory . decline Key : Facts A decline in somatostatin-positive interneurons in the hippocampus was linked to significant memory challenges in . mice Toxin-injected mice with reduced interneurons showed increased microglial
