Key Parameters

Metrics automatically extracted by ConductVision.

Total Distance

Cumulative walking distance over the recording session, reported in millimeters with per-minute time bins

Mean Velocity

Average walking speed during active bouts, excluding quiescent frames below configurable threshold

Activity/Rest Ratio

Proportion of time in active locomotion vs. quiescence, using species-standard 5-minute inactivity criterion

Boundary Interaction

Time and frequency of contact with arena walls, quantifying thigmotaxis as a proxy for anxiety-like behavior

Angular Velocity

Rate of heading change per frame, distinguishing exploratory turning from stereotypic circling patterns

Bout Duration

Length of consecutive walking episodes separated by pauses, analyzed as gamma-distributed bout architecture

+ 4 more parameters trackedShow all

Path Tortuosity

Ratio of actual path length to straight-line displacement, distinguishing directed locomotion from random walk

Maximum Speed

Peak instantaneous velocity within each active bout, sensitive to motor neuron and muscle function deficits

Center vs. Periphery Time

Fractional occupancy of inner arena zone relative to wall-adjacent annulus, an open-field anxiety metric

Initiation Frequency

Number of locomotor bout starts per minute, reflecting arousal state and dopaminergic drive

What is Drosophila Locomotor Activity Tracking?

Locomotor activity tracking is a foundational Drosophila assay for assessing motor function, arousal, and drug effects. Changes in walking speed, activity patterns, and rest/wake balance are sensitive indicators of dopaminergic modulation, circadian disruption, neurodegeneration, and the sedative or stimulant effects of compounds.

ConductVision provides sub-millimeter tracking in single-fly or multi-fly arenas, outputting distance, velocity, activity bout statistics, and time-binned activity profiles. The system supports both open-field and shallow-chamber formats for high-throughput pharmacological screening.
