Optimists exhibit similar brain activity patterns, while pessimists have varied, unique brain patterns. This finding suggests mental-health implications since pessimism is linked to depression. The COVID-19 pandemic has accelerated brain aging in healthy individuals, evidenced by structural changes in brain scans, while cognitive decline in mental agility was noted only in COVID-19 infected individuals. Additionally, a study showed that US academics increase their publication rates significantly in the year before obtaining tenure status, indicating a shift in research productivity after securing this job security.
A brain-imaging study reveals that optimistic people's brain activity patterns are alike, whereas pessimists exhibit more varied and idiosyncratic brain activities, suggesting implications for mental health.
During the COVID-19 pandemic, healthy individuals' brains aged faster than those analyzed before, with cognitive tests indicating mental agility declined only in those who contracted the virus.
Research revealed that US academics' publication output fundamentally shifts upon securing tenure, with a peak in production occurring in the year prior to tenure.
The research highlighted a visible connection between abstract feelings of collective thinking among optimists and the physical brain activity patterns that correspond to these feelings.
