Spinal cord motor neuronProximal equivalent dendriteGlycineIa interneurons release GLYGlycine from some Renshaw interneurons; IPSPs are Cl- mediated, potentially blocked by strychnine (Cullheim S and Kellerth JO, 1981 [cat ]26 ). Ia IPSPs are chloride mediated (Coombs, 195229 ); blocked by strychnine. Ia IPSPs are located near the cell soma (Burke RE et al, 1971 [cat ]60 ; reviewed in Young and MacDonald, 198323 ). Ia IPSPs are readily affected by soma current or Cl- injection, indicating location at the soma or proximal dendrites (Burke RE et al, 1971 [cat ]60 , SOBiv p94). Glycine ionophoresis mimics Ia IPSPs (reviewed by Young and MacDonald, 198323 , SOBiv p94). Ia IPSPs are blocked by strychnine, a known blocker of Glycine receptors (SOBiv p94).
