Summary of the data

This dataset contains in vivo two-photon Ca2+ imaging recordings obtained from Layer 2/3 somatosensory cortex of several mice of two genotypes (wild-type C57/B6 and Fmr1 knock-out) and three developmental age groups (postnatal days 9—11, 14—16, and 30—40). The mice were un-anesthetized, head-fixed, and not engaged in any experimental task. The dataset comprises: 1) the raw TIFF imaging movies, 2) estimated firing rates of individual neurons (MATLAB), and 3) the estimated anatomical distance between each pair of recorded cells (MATLAB). The number of animals in each group ranges from 6—13, while the number of simultaneously imaged neurons in each animal ranges from 40—149. Each recording was performed at a frame rate of 3.9 Hz, and the total duration of each recording is approximately 7—8 minutes.
