In Aplysia, the number of neurons involved in the memory circuit does not increase with the acquisition of a new memory. Rather, the existing neurons in the circuit undergo changes such as an increase in neurotransmitter production, branching of interconnecting branches, and the formation of new synapses. These changes facilitate the formation and storage of the new memory.
