The role of MSH in man is unknown. Administration of 10 mg synthetic alpha melanocyte-stimulating hormone (MSH) to 5 human subjects resulted in a significant increase in the averaged somatosensory cortical evoked response (AER). This change in the amplitude of the somatosensory evoked response was so marked that it could be seen on single trials of the EEG. The AER further increased during attention. Performance on the Benton Visual Retention Test also improved significantly after infusion of MSH. These findings demonstrate extra-pigmentary effects of MSH in man and suggest an effect upon the attentive process.
