From: Auditory evoked BOLD responses in awake compared to lightly anaesthetized zebra finches
BOLD responses in the zebra finch auditory forebrain in response to sound (vs rest) for the different conditions. (a) The images represent results of the voxel based group analysis for all sounds > rest (one-tailed t-tests) in awake, Med/Iso anaesthetized or isoflurane anaesthetized conditions. T-values are colour coded according to the scale next to the figures and only voxels with T-values > 3.32 (p uncorrected < 0.001) are displayed. The statistical maps are superimposed on images from the population based template. (b–d) The graphs illustrate the cluster size (b), peak T (c) and mean T (d) of the activated cluster within the auditory forebrain in response to sound in awake, Med/Iso anaesthetized and isoflurane anaesthetized conditions. Individual measurements are depicted by grey circles and the group mean by the black line (*p < 0.05; °p < 0.10).
