Sniff response of patients and healthy controls during odor detection. A, Difference measurement between non-odor and odor sniffs. Means and SE bars are plotted (blue, control group; cyan, right thalamic lesioned patients; green, left thalamic lesioned patients). The difference between odor and non-odor sniffs was significant among healthy controls and right thalamic patients only. Left thalamic lesioned patients did not modulate their sniff in relation to odorant content. B, Left and right thalamic lesioned patients took sniffs that were similar in duration but significantly reduced in volume compared with healthy controls. Normalized means and raw SE bars are plotted. B1, Sniffs of non-odor stimuli; B2, sniffs of odor stimuli.
