Calcium signaling is indeed crucial for various cellular processes, including neuronal communication. Neurons often use changes in intracellular calcium levels to transmit signals. These fluctuations in calcium concentrations play a role in processes such as neurotransmitter release and synaptic plasticity.

Systems context can change things and I'm not sure exactly how it's implemented in the brain, but I did some research modeling the Morris-Lecar neurons and, due to their slowness (relative to sodium-based models), you can get all kinds of neat of feedback and interference effects (in fact, chaos, when you couple many of them together via gap junctions.)

Another project I did for one of my theses was calcium-induced calcium release with calcium-modulated receptors, which is neat because it demonstrates a sort of interface between chemical and electrical signaling via activation that you don't get to explore much in pure ion models. This then allows a single neuron to have state transitions with "memory" (hysteresis - not to be confused with human memory).

And, In a groundbreaking discovery, scientists have uncovered a calcium-based signaling system within the human brain, a phenomenon never before observed. This unprecedented finding sheds new light on the intricacies of brain function and opens doors to a deeper understanding of neurological processes. I you want further information go here.
