^a,d Means (± SE) within a column not sharing a common superscript differ (P < 0.05).

VCL = curvilinear velocity (µm/s); VSL = straight line velocity (µm/s); VAP = average path velocity (µm/s). LIN = linearity, ratio in percentage of VSL/VCL (%); STR = straightness, VSL/VAP; ALH = amplitude of lateral head displacement (µ).
