Cercus Electric Stimulation Enables Cockroach with Trajectory Control and Spatial Cognition Training.

Area of Science:

• Neuroscience
• Robotics
• Animal Behavior

Background:

• Cyborg insects offer adaptable platforms for detection and recognition tasks via electrical stimulation for locomotion control.
• The potential for these control strategies to enhance insect memory formation and training remains largely unexplored.

Purpose of the Study:

• To investigate if artificial locomotion control strategies can induce memory formation in cyborg insects.
• To evaluate the efficacy of electrical stimulation for training cockroaches in a T-maze for spatial recognition.

Main Methods:

• A steering control strategy was applied to cyborg cockroaches during operant learning in a T-maze.
• Unilateral cercus electrical stimulation was used to induce steering behavior and guide locomotion.

Main Results:

• Cockroaches demonstrated a significant preference for specific maze channels after only five training sessions.
• A memory score of 83.5% was achieved, surpassing traditional punishment-based training methods.
• Electrical stimulation of the cercus was confirmed to improve spatial cognition and choice-making.

Conclusions:

• Artificial locomotion control facilitates predetermined insect movement and promotes preferential memory formation for specific paths.
• Electrical stimulation of insect sensory organs presents a potent and efficient training method for spatial recognition learning.
