Modulation of Electrocortical Brain Activity by Attention in Individuals with and without Tinnitus
Table 2
Relationship of ASSR and N1 responses on passive blocks and ASSR and N1 attention effects to subject and tinnitus variables. The table entries are product-moment correlations reported for the 500 Hz and 5 kHz conditions separately.
