    According to the researcher's report, the tufted tit can use a mammalian-like neural mechanism to process spatial memory
    .

    The tufted tit is a small songbird with a strong memory
    .

    Storage animals like tufted tits have excellent memories, they can accurately remember the location of thousands of hidden food places in the environment
    .

    Therefore, they are often regarded as models of spatial memory and idols of higher cognition among animals in textbooks
    .

    Although vertebrates with spatial memory are very common, the anatomical structure of the hippocampal brain regions related to this memory differs among vertebrates of different branches
    .

    Therefore, it is generally believed that the memory neural mechanism used by non-mammalians is very different from that used by mammals
    .

    Hannah Payne and colleagues used electrophysiological recordings of free-moving birds to analyze neuronal activity in the hippocampal homologous organs of tufted tits and zebra finches; these two birds have or do not have feeding behavior, respectively
    .

    Payne et al.
    discovered mammalian-like neural activity in the hippocampus of the tufted tit, including sharp wave ripples and ordered spatial recognition cells in anatomical structures
    .

    However, compared with tufted tits, non-storage zebra finch hippocampus has weaker and less space-related neural activities
    .

    These findings suggest that the basic neural mechanisms of spatial memory in birds and mammals are similar, and they are conserved in a variety of very different hippocampal brain circuits
    .
