Treatment-induced aphasia recovery studies with PET and MEG

Study	Aphasia types	LBT	Treatment	Dosage	Scan task (study)	Activation changes^*
Cornelissen et al. [13]	3 anomic	Naming	Contextual priming	3 wk; 3 1-h sess/wk	Delayed naming (MEG)	LH inferior parietal lobule (perilesional)
Breier et al. [43]	1 expressive and receptive	Unspecified; requesting items and responding to requested items	CIAT using dual card task	3 wk; 4 3-h sess/wk	Target word comprehension (MEG)	RH language homologues: immediate increase; BL recruitment after 3 mo of treatment
Raboyeau et al. [52]	2 Broca	Naming	Lexical training	4 wk; 5 15-min sess/wk	Picture naming in English and French (PET)	RH insula and inferior frontal gyrus
	3 conduction
	4 anomic
	1 apraxia of speech

Pretreatment to posttreatment activation changes, correlated with improved language function.

BL—bilateral; CIAT—constraint-induced aphasia therapy; LBT—language behavior targeted; LH—left hemisphere; MEG—magnetoencephalography; PET—positron emission tomography; RH—right hemisphere; sess—sessions.
