Is Handedness Associated with the Depth of the Olfactory Sulcus?

Background: Structural and functional asymmetry is frequent in biological systems. The aim of the present study was to examine whether there is a relation between handedness and the depth of the olfactory sulcus (OS) and reinvestigate whether there is a lateralization of OS depth.

Methods: Forty-two healthy volunteers (mean age 24.

Examination of olfactory training effectiveness in relation to its complexity and the cause of olfactory loss.

Objective: Although the effectiveness of olfactory training (OT) had already been documented, the optimal regimen for such training remains unexplored. We examined whether the complexity of OT, namely alteration of odor quantity and quality, increases its effectiveness.

Design: One-hundred eight patients (M = 60.
