Hoverfly Optic Flow Neuron Responses to Figure Motion

Featuring neural impulse responses from hoverfly lobula plate tangential cells (LPTCs) to figure motion stimuli. The data were generated using maximal length shift register sequences (m-sequences) to investigate spatio-temporal dynamics. The author is Yu-Jen Lee.

Use Cases

• Analyze the time course of impulse responses to figure motion stimuli across different figure sizes.
• Compare impulse response time-to-peak and half-width between low-contrast and standard stimuli.
• Investigate differences in impulse response time-to-peak between female and male hoverflies.
• Model the relationship between figure size and the amplitude scaling of the neural impulse response.
• Compare the shape of impulse responses to figure motion versus widefield stimuli to infer shared neural inputs.

Strengths

• Data generated using m-sequences, a white noise technique effective for extracting response kernels in insect motion vision.
• Includes comparative analyses across stimulus conditions (figure size, contrast) and biological sex.
• Released under a permissive CC0 1.0 public domain license.

Limitations

• The specific data format, row count, column structure, and file size are unknown.
• The dataset scope is limited to a specific neural cell type (LPTCs) in a single insect species (Eristalis tenax).
• Sample data is unavailable for preview, hindering initial assessment of data structure.
