New research sheds light on how the brain's prefrontal cortex evaluates whether to persist or quit in uncertain situations. Using tasks mimicking real-life dilemmas, researchers found that different brain regions influence patience and adaptability.

 

 

Research reveals that the orbitofrontal cortex (OFC) and hippocampus (DH) play distinct roles in resolving ambiguous situations where the meaning of stimuli changes based on context. The OFC helps regulate behavior by using contextual knowledge, while the DH is critical for applying prior knowledge to accelerate learning new relationships.

 

 

New research suggests that certain nutrients may lower iron buildup in the brain, a factor linked to cognitive decline in aging. Excess non-heme iron, which accumulates over time, contributes to oxidative stress and can impair memory and executive function.

 

 

A new study reveals how the brain forms cohesive mental maps of spaces and highlights the critical role of sleep in this process. While "place cells" in the hippocampus mark specific locations, weaker spatial cells stitch these points into a comprehensive cognitive map.
