[Effect of stimulation of splanchnic mechanoreceptors on the activity of purkinje cells (author's transl)].
Climbing and mossy fibre activity in Purkinje cells of cat cerebellum (vermis part of lobules V and VI) were recorded by means of extracellular microelectrodes. Responses were obtained by stimulation of different types of mechanoreceptors in the gastro-intestinal tract: muscular receptors connected with C fibres, peritoneal movement receptors connected with A gamma delta or B fibres, Pacinian corpuscules connected with A beta fivres. The characteristics of the splanchnic fibre projections on this cerebellar area were defined. Splanchno-somatic, splanchno-visceral, and splanchno-cortical convergences were demonstrated.
