+
+The repository contains in vivo single unit activity (SUA) data recorded from the V1 and S1 areas of developing mice (5-12 postnatal days).
+
+
+## SUA
+
+SUA data is provided as two .csv files, one for the PFC and one for the HP.
+
+The first two columns give a unique single unit identifier.
+1. the first column corresponds to the animal ID (same as in the meta_data file)
+2. the second column corresponds to unit ID
+
+The third column corresponds to the channel on which the unit has been recorded from. There can be multiple units recorded from the same channel. 
+
+The columns from the forth onwards (a variable number for every row) correspond to the timestamps of spikes fired by that single unit. The timestamps are given with a sampling rate of 32kHz. 0 corresponds to the beginning of the recording.
