Neurobehavioral Plasticity: Learning, Development, and Response to Brain Insults

By Norman E. Spear; Linda P. Spear et al. | Go to book overview

neuropeptides improved the capacity to process stimuli when no suppression of irrelevant stimuli was required. However, in a selective attention paradigm, when suppression of irrelevant stimuli is required, these neuropeptides impaired the performance ( Born, Fehm, & Voigt, 1986). Creativity is defined here as the conceiving of something new. It is affected by many factors (education, inherited disposition, distress, knowledge, ambition, working conditions, etc.). The subconscious is important because it stores much more information than one is aware of, and it is here, according to Ochse ( 1990) and others, that creativity unfolds. Access to the subconscious is better when arousal is low. If ACTH/MSH neuropeptides increase arousal, they might have a negative effect on creativity. However, because these peptides can block selective attention, the amount of information in the subconscious may increase. This might have a positive effect on creativity. These considerations do not offer an answer to the question as to whether ACTH/MSH neuropeptides stimulate creativity, and it is therefore suggested that the influence of these neuropeptides on creativity in human volunteers be investigated.


ACKNOWLEDGMENT

This chapter is dedicated to Dr. Robert Isaacson, a creative scientist.
