A recent study by the Max Planck Institute for Human Development found that spending time outdoors positively affects brain structure and gray matter in the right dorsolateral-prefrontal cortex. This area is involved in planning, regulation of actions, and cognitive control. The results persist even when other factors are kept constant.
A study of 1,978 people with an average age of 80 found that those who engaged in cognitively stimulating activities such as reading and playing card games delayed the onset of Alzheimer's dementia by up to five years. The research suggests that it may be beneficial to start doing these things, even in your 80s.
Researchers discovered a link between theta rhythm of the brain and gender differences in attitudes towards risk. The study found that men showed a higher risk appetite than women, with stronger frontal theta asymmetry and oscillations in the anterior cingulate cortex correlating with risk-taking behavior.
A recent meta-analysis found that acute aerobic exercise temporarily improves cognitive performance. However, approximately 50% of studies failed to show a link between the two. The analysis revealed that benefits were greater in those with lower pre-test scores and were more generalized across different types of cognitive performance.

The majority of younger patients under 50 exhibit these symptoms, highlighting the need for adequate support and treatments to alleviate symptoms.
A long-term study on wild chimpanzees found that young orphaned chimps experience high levels of stress when their mothers die, but this stress subsides over time. Adult orphaned chimps are supported by other chimps, which may contribute to their recovery from maternal loss.

The researchers suggest that variations in wellness visits and cognitive assessments between Medicare coverage types are not well understood, and more research is needed to validate the differences.
A new study shows that getting only half a night's sleep hijacks the brain's activity during learning and memory consolidation, leading to increased vulnerability to conditions like anxiety and posttraumatic stress disorder. The research found that even partial sleep deprivation can be worse than no sleep at all.
A study published in eLife found that individuals with bipolar disorder who exhibit pessimistic beliefs are more likely to experience relapse. The study suggests that the way patients update their beliefs can be used as a risk prediction tool, allowing for timely intervention and improved outcomes.

Researchers from UNIGE discovered that when the neuronal fibres connecting the hemispheres are missing, the brain reorganises itself and creates new connections. Intra-hemispheric connections increase, enabling communication between the two hemispheres to be maintained.
A brain protein that regulates time-keeping also plays a crucial role in normal memory formation, according to new research in fruit flies. Memory regulation by this protein, PDF, likely occurs without direct signaling to the main memory structure.
A multidisciplinary team has successfully visualized superficial white matter in living human brains using high-field MRI. The study reveals that this region contains significant amounts of iron, necessary for myelination, which can occur throughout lifespan but is predominant during development.
A new study from Colorado State University found that older adults who spent more time sitting performed better on vocabulary and reasoning tasks, contrary to expectations. The study suggests that sedentary time may be meaningful for cognitive health, especially when accompanied by educational activities.
A study found that people with severe apathy are 80% more likely to develop dementia than those with low apathy. Greater apathy was also associated with worse cognitive scores, highlighting its potential as an early sign of the disease.
