Fig 3. Paradigm for recording spontaneous and odor-evoked LFPs from head-fixed awake mice.

Fig 3.

A, After a variable inter-trial interval (ITI), the odor valves are turned on for 8 secs and the vacuum for 4 secs. This allows the animal to be presented with an odor for 4 secs. B, Schematic showing the recording paradigm. An epoch of spontaneous LFP activity was recorded before and after odor presentation. During odor presentation, 7 odors were presented in a pseudo-random order for 4–5 sessions, and their odor-evoked activity recorded. C, Average photoionization detector trace in response to 12 presentations of 1 Torr isopentyl acetate, depicting the rapid temporal dynamics and stability of odor presentation (10 Hz, low pass filtered). Data are mean +/− SEM.
