Extracellular CA1 spike trains recorded from Fmr1-null and wild-type mice during free exploration in a variety of environments that include a small and a large box, a ring, and a circular open field that is either stationary or rotating.

The data are extracellular single unit action potential, spike trains recorded from the hippocampus CA1
region of freely-behaving wild-type (WT) and Fmr1-null mice. The recordings were made using tetrodes and
the Axona dacqUSB recording system, while the mice explored open field environments. Spike sorting was
performed manually and single unit isolation quality was quantified using the IsoIBG and IsoINN measures
(Neymotin et al., 2011). Results from these data are reported in Talbot et al., (in press), Dvorak et al.,
(in press) as well as BioRxiv doi: https://doi.org/10.1101/152462 and BioRxiv doi: https://doi.org/10.1101/152488,
respectively.
