Dopamin und das Warten auf Belohnungen🤩🎁
Eine neue Studie zeigt, dass L-DOPA, eine Vorstufe des Neurotransmitters Dopamin, Menschen dazu bringt, länger auf Belohnungen zu warten. Sie zeigt, dass der Effekt einer Verringerung der Impulsivität um etwa 20 % entspricht.

‼️New preprint‼️
There does not seem to be an effect of ghrelin on risky decision-making in probability discounting. Not in behaviour, underlying computational processes, or neural activity.
