The Gate Theory of Pain Revisited: Modeling Different Pain Conditions with a Parsimonious Neurocomputational Model

Table 1

Configuration of a standard training epoch: (a) shows four binary combinations in terms of the presence/absence of certain nociceptive/mechanoreceptor input. (b) represents the same table in terms of afferent nociceptors and mechanoreceptors’ firing probabilities. Taking into account that axons of afferent nociceptors are not myelinated, their firing probability is lower than in the case of afferent mechanoreceptors.

(a)

Nociceptive input	Mechanoreceptor input
0	0
0	1
1	0
1	1

(b)

Nociceptive input	Mechanoreceptor input
0	0
0	0.6
0.3	0
0.3	0.6
