Vision Drives Accurate Approach Behavior during Prey Capture in Laboratory Mice.

Area of Science:

• Neuroscience
• Ethology
• Behavioral Biology

Background:

• Advancements in genetic tools facilitate neural circuit research in mice.
• Previous studies on mouse visual behavior primarily focused on fear responses.
• Understanding complex, ethologically relevant behaviors requires further investigation.

Purpose of the Study:

• To investigate the role of vision in prey capture behavior in mice.
• To determine the necessity of visual input for accurate orienting and approach behaviors.
• To develop an assay for analyzing visually guided approach in an ethological context.

Main Methods:

• Differential perturbation of visual and auditory input in mice during prey pursuit.
• Development of a simplified assay to isolate visual cues and analyze approach.
• Quantification of approach accuracy and capture rates with and without visual input.

Main Results:

• Mice robustly pursue, capture, and consume live insect prey.
• Vision is essential for maintaining accurate bearing towards prey during approach (within 11°).
• Capture accuracy and rate significantly declined when visual input was perturbed.

Conclusions:

• Laboratory mice exhibit dynamic, visually guided approach behaviors during prey capture.
• Vision plays a critical role in the accuracy of approach and capture success.
• The developed assay provides a method to study visually guided behaviors in an ethological context.
