...Georgia M. Shambes; John M. Gibson; Wally Welker We defined spatial patterns of tactile projections to cerebellar cortex of anesthetized albino rats using microelectrode micromapping methods. Low threshold natural stimulation of cutaneous mechanoreceptors of specific body structures evokes brisk...

.... Somatosensory Cutaneous Allometry Comparative method In vertebrates, sensory specializations are usually correlated with increases in the brain areas associated with that specialization. This correlation is called the ‘principle of proper mass’ whereby the size of a neural structure is a reflection...

...Jon W. Joseph; Georgia M. Shambes; John M. Gibson; Wally Welker We discovered a small tactile area in a single folium of the uvula of the caudal vermis of the rat's cerebellum. Gentle mechanical stimulation of relatively small cutaneous receptive fields (RFs) activated multiple units in the granule...

...) micromapping methods and low-threshold cutaneous (tactile) stimulation. Two sampling strategies were used: (1) a single cerebral SI locus in layers V-VI was stimulated electrically, while a responding region of the cerebellar granule cell (GC) layer was systematically mapped with a recording electrode; (2...
