Information about fcx-1 (frontal cortex, number 1).


This data was recorded using silicon probe electrodes in the frontal cortices of male Long Evans rats between 4-7 months of age. The design was to have no specific behavior, task or stimulus, rather the animal was left alone in it’s home cage (which it lives in at all times). Data includes both local field potentials (LFP) and spikes. 11 total animals, 27 recording sessions, 1360 total units recorded, 1121 units considered stable, 995 putative excitatory units and 126 putative inhibitory units. Only recordings including a “WAKE-SLEEP” episode wherein at least 7 minutes of wake are followed by 20 minutes of sleep. On average 2 such WAKE-SLEEP episodes per recording session. The data is used in the following publication:

Network Homeostasis and State Dynamics of Neocortical Sleep. Watson BO, Levenstein D, Greene JP, Gelinas JN, Buzsáki G.; Neuron. 2016 Apr 27. pii: S0896-6273(16)30056-3. doi: 10.1016/j.neuron.2016.03.036

Of note, Table 1 and Supplementary Figure 1 contain histological and overview data as well as definitions of brain states used.

Format of the data.

Data are organized into folders. Each folder contains the data for one recording session (lasting between about 1 and 8 hours duration). Data are mostly in .mat matlab format, there are also .csv files and lfp data in binary files called either .eeg or .lfp. More information is given in the data description document, linked to at the bottom of this page. Total size of the data is about 83 GB (compressed)
