on the basis of increased electron density as a selective `` '' labelling ' , sg cells are shown to be postsynaptic both to thin ( a delta and c ) and to thick ( a beta ) afferents as well as to descending ( or propriospinal ) fibres , while their recurrent axon collaterals establish inhibitory synapses upon somata of neighbouring sg cells and upon a beta terminals .
