    Working memory refers to the short-term storage and manipulation of external information, which is the core function of brain cognition.
    Remembering and dialing a new number, chatting with friends, and listening to a lecture all require the participation of working memory.
    Based on previous findings, the research team of Luo Huan from the School of Psychology and Cognitive Sciences and the McGovern Institute for Brain Research has successfully developed a new "dynamic disturbance" behavioral paradigm, which presents a number of specific temporal relationships in the memory retention stage.
    The dynamic brightness sequence manipulates the human sequence working memory.
    The research team further cooperated with the researcher Mi Yuanyuan of Chongqing University to establish a neural network dynamics model to simulate the process, revealing the principle of neural network short-term synaptic plasticity behind "dynamic disturbance".
    The research has developed an original working memory manipulation paradigm, which provides new causal evidence for the dynamic neural mechanism of memory, and also provides new ideas in the time dimension of biological inspiration for artificial intelligence and brain-like research.

    There are two ways to understand the working principle of the human brain: forward and reverse: research on human brain activity to understand cognitive brain mechanisms; discover and design reverse input to manipulate cognitive behavior based on brain mechanisms.
    The Luo Huan team’s previous work suggested that 100-300 milliseconds is a window for working memory to store and integrate multiple objects (eLife, 2018).
    A subsequent hypothesis is: Is it possible to design an input that conforms to the working principle of the memory window to change or even manipulate memory in a "stealing way"?

    In a series of working memory experiments, the researchers manipulated the memory by presenting a flashing disk during the memory retention stage, and the results confirmed the effectiveness of this operation method (see Figure 1).
    Furthermore, Luo Huan's research group and the researcher Mi Yuanyuan of Chongqing University have cooperated to establish a neural network dynamics model to simulate the "dynamic disturbance" memory manipulation process (Figure 2).
    The memory reading performance of the model completely repeats all the aforementioned behaviors.
    Manipulate the results and reveal that "dynamic disturbance" is the effective manipulation of network storage information through short-term synaptic plasticity.
