Memory doesn't belong to you! Nature Sub-journal New Study: Collective Memory Changes Individual Memory.
Time of Update: 2020-07-23
the research team pointed out in the paper that when people are asked to remember something, they will replace their actual experience with these collective memories, which shows that these memories are "co constructed" by collective memory and personal memory, which are interwoven with the brain's coding of memory.

Nature Sub-Journal: The seahorse circadian clock reveals the role of time in regulating memory recovery.
Time of Update: 2020-07-23
subsequently, the researchers traced the role of BMAL1 in memory retrieval to the hippocampus, and found that the memory retrieval ability of BMAL1 deficient mice was related to the down-regulation of dopamine cAMP signal in hippocampus, and the crosstalk between D1 / d5r and cAMP signal controlled by the hippocampal biological clock affected the time rule of memory retrieval, and BMAL1 mediated Da D1/ D5r and cAMP signal transduction can enhance memory retrieval by targeting GluA1 s845 phosphorylation.

Current Biology . . . How long meat you eat at night is dopamine in the brain's biological clock center.
Time of Update: 2020-07-23
this study revealed the important role of dopamine type 1 receptor-mediated dopamine signaling pathway in the regulation of eating time, food intake and weight gain in the hypothalamus.
this proves that DRD1 mediated dopamine signaling pathway in the suprachiasmatic nucleus alone is enough to make mice overeat high-fat food and become obese.
