Global differences in EEGs between the healthy subjects and tinnitus patients.

Condition	Number of tests performed	Number of significant tests	Significance
Basic recording	228	6	0.9734
Eyes open	228	3	0.9969
Acoustic stimulation	228	10	0.5910
Photostimulation	228	7	0.8870
Hyperventilation	228	34	0.0000
Pathologic patterns	152	26	0.0000

Number of tests performed: measurements of mean and maximal amplitudes of cortical activity gathered from each EEG electrode (together = 228 results to compare); number of significant tests: number of tests showing a significant difference (p<0.05) between the healthy and tinnitus groups based on Student's t-test; significance: results of Student's t-test for the whole analyzed condition. Significant differences between groups with regard to hyperventilation are explained in the Discussion (line 11).
