- •
Reading comprehension deficits in aphasia modulated predictability effect on N400.
- •
Patients with higher comprehension ability are more likely to show the typical N400.
- •
Low reading ability aphasics showed a prolonged and anterior-shifting N400 effect.
- •
The anterior-shift N400 may due to lesion or a greater reliance on frontal mechanism.
- •
Characteristics of N400 may index comprehension deficits and recovery in aphasia.
