title: Phase control of neural pacemakers.
abstract: An electrical stimulus resets the phase of a spontaneously rhythmic neuron. The "new phase" versus "old phase" curve shows either of two distinct topological characters, depending on the stimulus magnitude. These features, and a phase singularity implicit in them, are common to many stable oscillations deriving from continuous feedback between two or more biophysical quantities.
