|
+**Data Summary**
|
|
|
+
|
|
|
+The data set contains processed data from neurons in primary visual
|
|
|
+cortex of mice during presentations of static sinusoidal gratings. Mice
|
|
|
+were trained in either BCI experiments or visual discrimination
|
|
|
+experiments. In addition, neuronal data during BCI experiments are also
|
|
|
+present in this dataset
|
|
|
+
|
|
|
+**Visual Stimulus**
|
|
|
+
|
|
|
+The visual stimuli consisted of 180 full-field static gratings of
|
|
|
+various orientation and spatial frequency. The stimulus set was
|
|
|
+generated and presented using Psychtoolbox-3 in MATLAB. The code to
|
|
|
+generate and present the stimulus is 'presentStaticGrating_Rapid.m'
|
|
|
+
|
|
|
+**'allsignals.mat' File**
|
|
|
+
|
|
|
+Each grating presentation session has a MATLAB data file, corresponding
|
|
|
+to the session named 'allsignals.mat'. We used the MATLAB version of the
|
|
|
+Suite2P, not the PYTHON version. Note: only the variables that were used
|
|
|
+in the analysis of the data are described here.
|
|
|
+
|
|
|
+'**data**' variable contains the fluorescence intensity values of the
|
|
|
+cells as well as the frame at which each stimulus was presented. Each
|
|
|
+row represents a single 'file' recording. Each file of recording
|
|
|
+contains 4 repetitions through the 180 grating set.
|
|
|
+
|
|
|
+**[Variables saved in data]{.ul}**
|
|
|
+
|
|
|
+**dF**: neuropil-subtracted fluorescence trace of all the cells for each
|
|
|
+file. The dimension of the field is number of cells by number of frames.
|
|
|
+For details on neuropil subtraction, refer to
|

|
+<https://www.biorxiv.org/content/10.1101/061507v2>.
|
|
|
+
|
|
|
+**signal_decov:** deconvolved events amplitude for each neuron.
|
|
|
+
|
|
|
+**usable_motionCorrection:** If there was too much motion in the image,
|
|
|
+mark the frame. 1 means it is a usable frame, 0 means it is not.
|
|
|
+
|
|
|
+**usable_global:** frame by frame information on whether a given frame
|
|
|
+has a large drop in signal, 1 means it is a usable frame, 0 means it is
|
|
|
+not.
|
|
|
+
|
|
|
+**usable_eyetracking:** frame by frame information on whether the pupil
|
|
|
+was detected in a given frame. If not detected, the mouse was most
|
|
|
+likely blinking. 1 means it is a usable frame, 0 means it is not.
|
|
|
+
|
|
|
+**running_speed:** speed of the locomotion.
|
|
|
+
|
|
|
+**usable_balltracking:** frame by frame information on whether the mouse
|
|
|
+was in locomotive state. 1 means it is a usable frame, 0 means it is
|
|
|
+not.
|
|
|
+
|
|
|
+**usable_frames:** A frame is usable if and only if it passes the four
|
|
|
+"usable" criteria. 1 means it is a usable frame, 0 means it is not.
|
|
|
+
|
|
|
+**stimOn**: the frame at which a stimulus was presented. In each file,
|
|
|
+720 stimuli were presented.
|
|
|
+
|
|
|
+**stimBlocks**: the identity of the presented stimulus matching the
|
|
|
+presented frame information in '**stimOn**'. The first column of this
|
|
|
+variable is the unique ID assigned to the stimulus. The second column is
|
|
|
+the orientation of the stimulus in degrees. The third column is the
|
|
|
+spatial frequency of the stimulus in cycles per degree.

+**'BCIData.mat' File**
|
|
|
+
|
|
|
+Data file containing BCI experiment data.
|
|
|
+
|
|
|
+**cellTrackingData:** x-y coordinates of neuron location in pixels.
|
|
|
+
|
|
|
+**decoderData:** Contains direct neuron activity as well as the frame at
|
|
|
+which the trial started and ended. Length of this variable is the number
|
|
|
+of trials.
|
|
|
+
|
|
|
+**suite2pData:** suite2p fluorescence of all segmented neurons.
|
|
|
+
|
|
|
+**targetReachedProb:** proportion of trials that the target was reached.
|
|
|
+
|
|
|
+**baselineData:** Fluorescence data of all neurons in the field of view
|
|
|
+during baseline measurement.
