EEG

EEG is increasingly valuable in neuropsychiatry, aiding in the diagnosis and treatment of conditions like epilepsy, depression, and ADHD. It holds immense promise as a biomarker as it can pinpoint unique neural patterns associated with different disorders, even distinguishing between subtypes. This capability extends to monitoring disease progression and treatment response, including distinguishing between treatment and placebo effects. Consequently, EEG enables treatment customization based on individual patient profiles, paving the way for a new era of personalized medicine in neuropsychiatry.

Insights into Psychedelic Actions

EEG research is significantly advancing our understanding of how psychedelics influence the human brain. Here are several key findings:

• Disruption of Normal Brainwave Patterns: Psychedelics disrupt typical brainwave patterns, indicating that the brain is entering a unique functional state.
• Alterations in Brain Connectivity: Psychedelics promote hyperconnectivity and increased entropy across the brain, This allows for greater communication between different areas and networks, particularly those associated with higher-level functions like imagination. This hyperconnected state may underpin the changes in consciousness and perception associated with psychedelic experiences.
• Increased Neuroplasticity: One major finding is the sustained increase in theta power following psilocybin administration. Theta waves, associated with relaxation, creativity, meditation, and dreaming, are indicators of neuroplasticity. Their increase implies that psychedelics might promote neural flexibility, potentially leading to lasting changes in brain function.
• Correlation with Symptom Improvement: The increase in EEG theta power post-psilocybin administration correlated with improvements in depression symptoms. This suggests a direct link between the changes in brain activity induced by psychedelics and their potential therapeutic effects.
• Cross-species Similarities: The EEG patterns elicited by psychedelics in animals closely resemble those observed in human studies, indicating strong translational validity and hinting at a consistent cross-species mechanism of action.
• EEG is helping drive significant advancements in neuroscience by providing real-time insights into the intricate workings of the human mind. As technology advances, so too will our understanding of brain function. This will not only provide enhanced insights into underlying psychedelic mechanisms but also opens doors to pioneering novel treatments for various neuropsychiatric disorders.
