Hyperpolarization triggered burst firing in a subset of MHb neurons. A, Ramp hyperpolarization in a tonic firing neuron with a resting Vm of −40 mV converted tonic firing to burst firing. B, Progressively longer hyperpolarizing current injections triggered rebound burst firing in an MHb neuron. C, Progressively greater hyperpolarizing current injections triggered rebound burst firing in an MHb neuron. D, A 1.5-s-long hyperpolarizing current injection triggered rebound burst firing in an MHb neuron. E, Baseline state of MHb neurons that displayed burst firing from a hyperpolarized Vm (<−60 mV).
