How does the vagus nerve work?

Vagus nerve stimulation (VNS) works through a device implanted under the skin that sends electrical pulses through the left vagus nerve, half of a prominent pair of nerves that run from the brainstem through the neck and down to each side of the chest and abdomen. The vagus nerves carry messages from the brain to the body's major organs (e.g. heart, lungs and intestines) and to areas of the brain that control mood, sleep, and other functions.

What is the function of triggered neurotransmitter signals?

The triggered neurotransmitter signals become part of a computation of all the signals landing on one dendrite from many different neurons. The summation of all of these signals on the dendrite of a postsynaptic neuron determines whether the next neuron will send a signal or not.

How does the brain generate the mind?

The two major theories of how the brain generates the mind are the neuronal connections where electrical signals travel along axons triggering a chemical connection at another neuron’s dendrite ( see post Connectome) and electrical brain waves, which oscillate together at specific frequencies ( see post Brain Oscillations ).

In this experiment it appears that synchronous waves are ...

What is the electrical signal that travels along the axon?

This electrical signal, called the “action potential” travels along the axon and usually triggers the delivery of a neurotransmitter to another neuron. Occasionally this signal sends a more direct electrical signal through a “gap (electrical) junction,” to another neuron.

How do synaptic connections affect computation?

Perhaps the neuronal synaptic connections are involved in computation by summing the inputs in the network of connections arriving at the dendrite.
