我们研究了激活一个竞争性的、人工生成的神经表征对情境恐惧记忆编码的影响。我们使用基于cfos的转基因方法将hM3Dq DREADD受体引入神经元中,基于它们的自然活动模式。然后可以通过外源配体特异性地和诱导性地增加表达hM3Dq的神经元中的神经活性。当一个环境(ctxA)的神经元集合在不同环境(ctxB)的条件反射过程中被人工激活时,动物形成了混合记忆表征。在条件反射的背景下,人工刺激网络的重新激活是恢复记忆所必需的。记忆是特定的空间模式的神经元在学习过程中人工激活,而类似的刺激受损回忆时,不是最初的条件反射。
We investigated the effect of activating a competing, artificially generated, neural representation on encoding of contextual fear memory. We used a cfos based transgenic approach to introduce the hM3Dq DREADD receptor into neurons based on their natural activity patterns. Neural activity can then be specifically and inducibly increased in the hM3Dq expressing neurons by an exogenous ligand. When an ensemble of neurons for one context (ctxA) was artificially activated during conditioning in a distinct context (ctxB), animals formed a hybrid memory representation. Reactivation of the artificially stimulated network within the conditioning context was required for retrieval of the memory. The memory was specific for the spatial pattern of neurons artificially activated during learning while similar stimulation impaired recall when not part of the initial conditioning.
