A study comparing regular psychedelic users and non-users found differences in brain activity during self-reflection tasks, with users showing weaker activation in regions associated with self-processing, though results varied across datasets and may be influenced by lifestyle factors. The research highlights potential long-term effects of psychedelics on brain function related to self-related thoughts, but causality remains unclear.
A study found that higher cognitive ability is linked to better synchronization of brain regions, specifically through theta connectivity, which may serve as a marker for intelligence and cognitive control, with potential implications for future diagnostics and brain training tools.
A study by MIT researchers found that using ChatGPT for essay writing may weaken neural connectivity and reduce critical thinking skills, as evidenced by EEG analysis and performance assessments, raising concerns about the long-term educational effects of relying on large language models.
