Sequential organization after excitotoxin lesions: rates of syntactic chain completion. The percentage of first, second, third, and fourth grooming chains begun within a session that were completed syntactically (i.e., Phases I, II, III, and IV without interruption). Only rats with lesions of the anterior dorsolateral neostriatum had a reliable disruption of grooming syntax throughout a session. Abbreviations: VM STR., ventromedial neostriatum;VP, ventral pallidum; GP, globus pallidus;DM STR., dorsomedial neostriatum; VL STR., ventrolateral neostriatum; DL STR., anterior dorsolateral neostriatum.
