中文摘要 記憶在穩固化和再穩固化的階段,對於失憶及提升記憶的治療是相當容易受影響的。目前已知電痙攣刺激會減損記憶的穩固化作用。因此,我們假設記憶的再穩固化作用也可以受電痙攣刺激干擾。由古柯鹼誘發的小鼠制約場地偏好學習記憶模式中,發現當提取制約場地偏好的記憶後,立即在小鼠的兩耳耳廓上施予200毫秒的電痙攣刺激(500V, 25mA),該學習記憶的後來表現會因此減弱。相對的,未經提取制約場地偏好記憶時,雖然施予相同的電痙攣刺激,對場地偏好的行為表現並無影響。當記憶被提取後立即給予全身性Pentobarbital麻醉注射,並不影響爾後的制約場地偏好學習記憶表現;該現象在不同的電痙攣刺激程序,都發現Pentobarbital麻醉下的電痙攣刺激,對爾後的記憶表現並無影響。最後,分別以食物誘發的制約場地偏好學習記憶模式及被動規避學習試驗(Passive avoidance learning test),發現在非麻醉狀況下的動物,提取相關記憶後,立即給予電痙攣刺激,同樣可以減低動物對食物求償及恐懼記憶的行為表現。綜合以上結果,經由Pavlovian條件所建立的相關記憶,藉由短暫性的電痙攣刺激,可以破壞該記憶的再穩固化作用,降低爾後的行為表現,即使這些記憶已經形成或穩固一段時間,仍然有效。
英文摘要 The deduced memory consolidation and reconsolidation phases are both sensitive to similar amnesic and memory-enhancing treatment. Electroconvulsive stimuli have been well known to impair memory consolidation. Therefore, we hypothesized that electroconvulsive stimuli may disrupt memory reconsolidation. Delivery of a 200-msec electroconvulsive stimulus (500V, 25mA) between mouse pinnas immediately after recall of the cocaine-induced conditioned place preference (CPP) impaired the reconsolidation and subsequent expression of this memory. In contrast, a similar electroconvulsive stimulus did not affect subsequent cocaine-induced CPP performance when the recall procedure was omitted. Systemic pentobarbital injection immediately after the CPP test did not affect subsequent cocaine-induced CPP. Interestingly, various electroconvulsive procedures given immediately after the recall of cocaine-induced CPP did not affect subsequent CPP performance when mice were anesthetized by pentobarbital during the electroconvulsive procedures. Finally, delivery of this 200-ms electroconvulsive stimulus immediately after the reactivation of passive avoidance (PA) and food-induced CPP impaired subsequent performance of these memories in the retest. Taken together, we conclude that a short-lasting electroconvulsive stimulus can deteriorate the reconsolidation of various Pavlovian associative memories, therefore impair their subsequent performance even these memories are already established and stabilized.
