Answer: an activity state followed by a synaptic state.
Step-by-step explanation:
Mark Stokes introduced the theory that short-term variations in the neural networks can be responsible for information being collected in the memory.
There´re two states involved in this process. First, during the activity state, when the person is working to memorize information, several neurons are activated. This leads to the next step, the synaptic state when neuron firing discontinues.
