Neural Oscillators on the Edge: Harnessing Noise to Promote Stability
... Abnormal neural oscillations are implicated in certain disease states, for example repetitive firing of injured axons evoking painful paresthesia, and rhythmic discharges of cortical neurons in patients with epilepsy. In other clinical conditions, the pathological state manifests as a vulnerability ...

... Short-term sensitization of the gill-withdrawal reflex in Aplysia. A. Sensitization of the gill-withdrawal reflex is produced by applying a noxious stimulus to another part of the body, such as the tail. A shock to the tail activates tail sensory neurons that excite facilitating (modulatory) interne ...
