Interventions

Group 1: Ten patients with either left or right-sided pure hemianopia (without neglect) received one hour of unilateral passive auditory stimulation on either their anopic or their intact side by appl

upper cutoff frequency 11 kHz). Stimuli were trains of ten sound bursts. Each stimulus train had an overall duration of 960 ms

single sound bursts had a duration of 60 ms with triangular envelope (onset/offset time 30 ms) and were presented at a rate of 10 Hz. The stimulus trains were presented at a rate of one per 5 s (inter
