2026-07-30 A whole-brain dataset of astrocytic calcium and behavioral responses to directional visual motion in larval zebrafish doi:10.57760/sciencedb.42302 en The dataset contains six fish-level records, corresponding to `fish_1` to `fish_6`. Each record includes two major types of data: whole-brain astrocytic calcium imaging data, and synchronously acquired bilateral motor nerve/swim signals together with visual-motion stimulus information.  For the imaging data, `cell_resp_processed.stackf` stores the processed calcium activity traces of each astrocytic ROI over time. The matrix is stored as baseline-offset normalized fluorescence values; subtracting 1 gives the corresponding ΔF/F0 traces. `cell_resp_dim_processed.mat` records the dimensions of this matrix, including the number of astrocytic ROIs and the number of imaging frames. `cell_info.mat` provides basic spatial information for each astrocytic ROI, including the ROI center position, area, imaging plane, pixel indices, and bounding ranges. `ave.tif` contains the time-averaged image stack used for ROI detection and visualization of the imaged volume. In addition, each record contains files related to motion-correction quality control. `motion.tif` shows the segmented grids used for inspecting motion correction, `motion_graph.tif` shows drift changes of segmented grids across different imaging planes during the recording, and `motion_tcourse.tif` shows the drift time course of segmented grids in each plane across recording time points. These files are provided to evaluate motion drift and registration quality during the recording.  For the swim and stimulus data, `left_swim.mat` and `right_swim.mat` store the left and right swim signals, respectively. `orient.mat` stores the continuous visual-motion direction stimulus vector along the swim/electrophysiology sampling time axis. `trial_stage.mat` stores the trial-stage information used to define the temporal structure and order of the visual-stimulation epochs for each recording. `frames.mat` records the correspondence between imaging frames and swim/electrophysiology sampling points, enabling alignment among calcium imaging data, swim signals, and stimulus timing. `stages.mat` records the onset and offset of each stimulus event in temporal order using the swim/electrophysiology sampling rate as the time base, whereas `stages_framed.mat` records the onset and offset of the same stimulus events on the imaging-frame time axis. `trials.mat` records the total trial number during the recording period.
