Abstract :Learning and memory formation in living things is a subject under investigation. It is thought that the memory formed in the brain\\\'s neural network structure is closely related to the connections between neurons. Connections called \\\"motifs\\\" have been identified, usually consisting of three or four neurons and repeating within the neural network. The basic structure of biological memory is thought to be related to such repetitive neural connections. In this study; the effect of the structures of motifs on short- and long-term memory was examined for all triple-neuronal network motifs. We used the Hodgkin-Huxley model of neurons. Using graph theory, we generated all triple-neuron motifs. In the created motifs; the effects of synaptic inputs between neurons, types of synaptic inputs of neurons, and chemical synapse duration on short- and long-term memory were examined. From the data obtained in all triple-neural network motif models; from the structure of the motif and the type of synaptic input, we determined the status of long- and short-term memory. We classified all triple-neural network motifs for situations in which they exhibit short- and long-term memory behaviour. We show that short-term memory varies with synaptic connection duration.
