Natural Movie Stimuli for Retinal Recordings (100 clips)

This dataset contains 100 natural movie clips used as visual stimuli in multi-electrode array (MEA) recordings of retinal ganglion cells. These clips represent dynamic natural scenes designed to investigate neural coding under ecologically relevant viewing conditions. Dataset Contents: 100 unique natural movie clipsDuration: 2.5 seconds per clipFrame rate: 60 Hz (150 frames per clip)Spatial resolution: 72×72 pixelsTotal stimulus duration: 250 secondsFormat: MATLAB (.mat) files Each stimulus file contains: clip_frames: Three-dimensional array (5184, 150, clip_index) First dimension: Flattened spatial information (72×72 = 5,184 pixels)Second dimension: Temporal frames (150 frames at 60 Hz)Third dimension: Clip identifierData type: uint8 (0-255 grayscale intensity values) time: One-dimensional array (1, 150) Temporal timestamps for each frameData type: float64Units: seconds (0.0 to 2.5) Reconstructing 2D Frames:To convert the flattened spatial format back to 2D images: MATLAB: frame_2D = reshape(clip_frames(:, frame_idx, clip_idx), 72, 72);Python: frame_2D = clip_frames[:, frame_idx, clip_idx].reshape(72, 72)
