title: [Convergence of heterotopic nociceptive information onto neurons of the subnucleus reticularis dorsalis in the rat].
abstract: The nature of stimuli that activate neurones located within the Subnucleus Reticularis Dorsalis (SRD) was determined. These neurones do not respond to visual, auditory or proprioceptive stimuli but are preferentially or even exclusively activated by noxious stimuli applied to any part of the body; only neurones of a sub-group have a predominantly contralateral activation. All the neurones were exclusively activated by stimulation of A delta or A delta and C afferent fibres. These observations suggest that this well-delimited reticular structure is specifically involved in the processing of nociceptive information.
