title: Non-associative learning in the mouse. Effect of morphine and naloxone.
abstract: The study evaluates the effect of morphine and naloxone on the process of non-associative learning in the mouse. Exploratory behavior was measured in thirty-six male albino mice (Suisse) placed on a Boissier and Simon hole-board, the procedure being repeated 24 h later after administration of naloxone and/or morphine, or bidistilled water i.p. The results show that the inhibitory effect naloxone has on the recollection process of the mnemonic traces appears to be masked by morphine.
