Table 1 Statistical values obtained with sequences 1 and 2 in the single animal and group analysis

From: Auditory functional magnetic resonance imaging in dogs – normalization and group analysis and the processing of pitch in the canine auditory pathways

Sequence 1

  1. The average t-value of all voxels included in the ROI, the mean percentage signal change between sound and silence conditions and the percentage of voxels showing significant activation are listed for the different sequences and ROIs (CC caudal colliculi, MGN medial geniculate nuclei, TC temporal cortex). The statistical values for the subcortical ROIs are higher with sequence 1, whereas only sequence 2 recorded a positive t-value and signal change for the cortical ROI
