Toward this end, we have developed an integrate-and-fire model that predicts with millisecond …

Tactile allodynia is a symptom of neuropathic pain where normally innocuous moving tactile stimuli produce pain. People with tactile allodynia typically experience a burning, tender sensation during soft stroking of the affected skin (Rasmussen et al., 2004). Even a very light stimulus, such as a ...
