Receptive Field Locations of V1 neurons, supporting "Distance-tuned neurons drive specialized path integration calculations in medial entorhinal cortex"

During navigation, animals estimate their position using path integration and landmarks, engaging many brain areas. Whether these areas follow specialized or universal cue integration principles remains incompletely understood. We combine electrophysiology with virtual reality to quantify cue integration across thousands of neurons in three navigation-relevant areas: primary visual (V1), retrosplenial (RSC) and medial entorhinal cortex (MEC). The data shared here contains receptive field locations of V1 neurons recorded in this study.

Receptive_fields: Data from receptive field mapping experiments. Contains Folders for each Recording session. Each folder contains receptive field information for all ‘good’ units from VISp, from that particular recording. Data is contained in receptive_fields.mat with these fields:

-good_cells: list of VISp cluster IDs for which receptive fields were attempted to extract

-staMat: nRows x nCols x nRepetitions x nClusters spike triggered average of stimulus movie frames for each repetition of the stimulus movie

-fields: for each cluster, contains a list with number of extracted receptive fields (can be 0 if no significant receptive field was detected). Relevant variables are:

-field_sign: +/-1 for on/off field

-PixelList: list of significant pixels

-mu: (x/y) coordinates of center of receptive fields

-sig: 2D covariance matrix of gaussian fit

-xy: list of x,y coordinates of ellipse for plotting

-area: area of ellipse
