Ring of Neurons with Delayed Connections

The animations below show the oscillation patterns that can occur in a ring of neurons with timed delayed connections between the neurons. In each case, all neurons are oscillating with the same frequency, all that changes is the phase differences between the neurons and the amplitudes of the oscillations.

For an odd number of neurons there are 4 possible patterns.

For an even number of neurons two patterns are stable. All animations were prepared using XPPAUT.

Here is the pdf file of a talk relating to these animations.
