From crayfish to humans: An evolutionary perspective of addiction redalyc.org 6 facts
referenceDatta, U., Van Staaden, M., & Huber, R. (2018) demonstrated that crayfish self-administer amphetamine in a spatially contingent task.
claimLobsters and crayfish have been observed to develop a preference for the specific contexts in which they received a drug.
claimLobsters and crayfish exhibit a vulnerability to relapse similar to that of mammals such as humans.
referenceNathaniel, T. I., Panksepp, J., & Huber, R. (2010) studied the effects of single and repeated morphine treatment on conditioned and unconditioned behavioral sensitization in crayfish.
claimLobsters and crayfish are motivated to learn and perform simple operational behaviors to obtain a new dose of substances.
claimIn lobsters and crayfish, learning and associative memories linked to the reinforcing power of drugs are extinguished after pairings with a conditioned stimulus without drug administration, but reappear when the drug is readministered.
The Deep Evolutionary Roots of 'Addiction' mentalhealthjournal.org 3 facts
referenceHuber R, Imeh-Nathaniel A, Nathaniel TI, et al. (2018) explore the neural basis of addiction in crayfish using automated learning paradigms to study drug-sensitive reward.
referenceImeh-Nathaniel A, Okon M, Huber R, et al. (2014) observed exploratory behavior and withdrawal signs in crayfish following chronic central morphine injections and termination of the injections.
referenceAlcaro A, Panksepp J, and Huber R (2011) report that D-amphetamine stimulates unconditioned exploration and approach behaviors in crayfish, suggesting a conserved evolutionary function of ancestral drug reward.
