motivene
Motivene is a term used in speculative science to denote a hypothetical chemical compound or class of compounds argued to influence motivational states or energy allocation in living systems. It is not an established molecule in chemistry or neuroscience, and it does not appear in major databases or peer-reviewed literature as of this writing. In hypothetical models, motivene might act as a neuromodulator that biases neural circuits related to reward, effort, and action selection, potentially affecting the balance between exploration and exploitation. In other uses, motivene may be imagined as an energy substrate that increases the efficiency of neural processing related to goal-directed behavior. The idea is often employed in thought experiments about motivation, behavioral economics, or bioethical discussions surrounding neuromodulation.
Etymology is uncertain; the word appears to combine motive or motivation with the chemical-sounding suffix -ene.
Because motivene lacks empirical support, any claims about its effects are speculative and not experimentally validated.
