Recently, researchers in the Department of Neuroscience at the Scripps Institution in Florida found that dopamine neurons in fruit flies mediate memory suppression for short-term forgetting, the first time scientists have discovered a neurological mechanism of temporary forgetting.
the study, published in the journal Nature, is entitled Dopamine-base mechanism for transient forgetting.
study, researchers conducted a series of experiments and analyses on fruit flies to find a pair of neurons, PPL1-alpha2 alpha'2, that mediated temporary forgetting.
When the neuron is artificially stimulated, the neuron releases dopamine, which briefly inhibits the retrieval function of memory memory, resulting in the inability to effectively extract long-term memory, which can be recovered over time.
further study found that this transient forgetting mechanism is triggered by disturbing external stimuli before retrieving memory memory, and that these neurons can restore memory by stimulating dopamine DAMB subjects.
researchers believe that temporary oblivion may be a protective mechanism for living things, and similar mechanisms exist in humans.
the study also adds new clues to the mechanisms of human learning, memory and active forgetting.
