Repeated actions with a specific purpose create habits in the brain, and thus the speed of information transmission and information storage is improved, which is explained by brain neuroplasticity, or the increase in the number of synapses. The process of learning is the main factor in increasing the number of synapses and is the basis of intelligence. Neurons and synaptic structures, which are the main features of memory, are formed through regular exercise and support our brain's ability to transmit and store information. Based on the neurobiological factors of the brain, this research article tries to explain how this ability to store and express information is the main measure of human intelligence
