Summary

Evoked potentials (EP) offer insights into psychopharmacology by measuring rapid brain activity. While not specific for classifying drugs, EP show promise in predicting patient responses to treatments like stimulants and lithium.

Context:

Evoked potentials (EP) serve as a crucial research tool in psychopharmacology, bridging neurobiological and psychological descriptions of central nervous system processes.
EP allow for the investigation of neural activity within millisecond timescales, offering high temporal resolution.

Purpose:

To review the literature on the effects of major psychoactive drug classes on evoked potentials (EP) in healthy subjects and patients.
To assess the suitability of EP as predictors for clinical response to psychopharmacological treatments.

Summary:

The review found that psychoactive drugs generally have non-specific effects on EP, which are influenced by subject-specific factors, treatment parameters, and recording conditions.
Consequently, the utility of EP for classifying new psychoactive drugs is currently limited.
However, EP research has contributed to psychological models of drug action and shows promise for predicting treatment response, particularly for stimulants and lithium salts.

Impact:

EP research has advanced the understanding of psychoactive drug mechanisms, informing psychological concepts of drug action.
The predictive value of EP for treatment response, especially for stimulants and lithium, suggests potential clinical applications in personalized psychopharmacology.
Further research into EP may refine the selection of psychopharmacological treatments for improved patient outcomes.
