There are some theories considering physiological mechanisms of short-term memory. According to the theory of reverberation of impulses a substratum storing the arriving information, the neural trap formed of a chain нейронов that provides long circulation of excitation on such ring communications is. If импульсация will repeatedly arrive to the same нейронам there is a fastening of traces of these processes in memory.
