Memory, defined as the storage and use of learned information in the brain, is necessary to modulate behavior and critical for animals to adapt to their environments and survive. Despite being a cornerstone of brain function, questions surrounding the molecular and cellular mechanisms of how ...
yup... competition between engrams influences fear memory formation and recall 2016-11-01 回复喜欢 Peng 我认为记忆是神经反馈的一系列活动,反馈活动主要由海马区主导,但存贮区域分散在多个部位,我生病后的情况就是,大脑有部分过往记忆,但不全,新的学习记忆绝大部份只能恢复到部分短时间存储,长时间存...
intrinsic cellular excitability — the propensity of a neuron to fire an action potential in response to input — can be a key determinant of participation in memory [16]. In the context of memory, neurons with high excitability can be biased towards ...
For instance, initially hippocampal-dependent memories become increasingly dependent on the cortex, including the anterior cingulate cortex (ACC), over time such that the hippocampus may not even be necessary for the retrieval of the memory at remote time points4,5. How can these observations be ...

Tremendous strides have been made in our understanding of the neurobiological substrates of memory – the so-called memory “engram”. Here, we integrate recent progress in the engram field to illustrate how engram neurons transform across the “lifespan” of a memory — from initial memory encodi...
