With the help of the models created and in the light of experimental studies, it is tried to understand the biological networks of memory structures and their motifs which is the basic building block of them. These are believed to be basic building blocks of neural networks and to perform important functional roles in them.. In this study we examined long term and short term memory functions of all neuronal motifs that consist of tree neurons. All motifs consists of three neurons which are modelled with single compartment Hodgkin Huxley neuronal model. The results show that a lot of motifs have revealed long-term and short-term memory behavior.
