Membrane Potential Records from Cat Visual Cortex Neurons in Response to Drifting Gratings

Membrane potential traces from neurons recorded in cat visual cortex from the Ferster Lab. The 16.7 MB dataset in MATLAB format contains responses to drifting gratings, with fields for sample rate, stimulus duration, and background potential. The data were published by Nicholas Priebe et al. in Nature Neuroscience in 2004 and last updated on 2026-05 06.

Use Cases

• Analyzing neural response dynamics to visual stimuli based on membrane potential traces.
• Studying the relationship between spike threshold and cell classification based on the associated publication.
• Modeling cortical simple and complex cell responses based on electrophysiological recordings.
• Benchmarking spike detection or signal processing algorithms based on raw membrane potential data.

Strengths

• Data is directly linked to a peer-reviewed publication in Nature Neuroscience (2004).
• Dataset size is 16.7 MB, making it manageable for download and local analysis.
• Specific metadata fields are described, including sample rate (datafreq) and stimulus parameters (stimdur, tf).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is stored in a proprietary MATLAB format, requiring specific software for access.
