Therefore, polyvagal theory predicts that the NA branch will inhibit acceleratory sympathetic nervous system (SNS) input to the heart when attention and social engagement are adaptive, and withdraw this inhibitory influence when fighting or fleeing are adaptive.Wiki.
Bounded function are timeless and spaceless, so we need a basic rate counter. The theory proposes the heart beat.
We pace our basic channel rate to match our bounded functions with others, a phase lock loop for interpersonal actions. Consider multiple individuals with a meeting function, a bounded function that defines action in a business meeting. Under the scenario that all members of the meeting agree on the bounds, then they would also have to agree on the basic rate. The heart would be a natural pace maker. Look up the Polyvagal theory, the theory talks about regulating channel rates.
And this:
The vast computational power of the brain has traditionally been viewed as arising from the complex connectivity of neural networks, in which an individual neuron acts as a simple linear summation and thresholding device. However, recent studies show that individual neurons utilize a wealth of nonlinear mechanisms to transform synaptic input into output firing. These mechanisms can arise from synaptic plasticity, synaptic noise, and somatic and dendritic conductances. This tool kit of nonlinear mechanisms confers considerable computational power on both morphologically simple and more complex neurons, enabling them to perform a range of arithmetic operations on signals encoded in a variety of different ways.
R. Angus Silver is doing the research on rate counter in our head. The brain paces a bounded function via phase locking.
