Does Dopamine Depletion Trigger a Spreader Lexical-Semantic Activation in Parkinson’s Disease? Evidence from a Study Based on Word Fluency Tasks

Table 2

Average (SD) number of words generated by PD patients and HC in the letter-cued and category-cued fluency tasks. Note that PD patients performed the tasks in two distinct pharmacological conditions (ON versus OFF L-Dopa treatment), whereas HC took no drugs prior to either task session.

	Letter-cued		Category-cued
	PD; ()	HC; ()	PD; ()	HC; ()
ON L-Dopa/green	26.7 (10.2)	31.2 (7.2)	21.9 (5.6)	21.6 (5.8)
OFF L-Dopa/blue	28.5 (10.7)	30.9 (8.6)	20.1 (8.3)	21.6 (4.5)
