RT Journal Article SR Electronic T1 Coupling of tactile LFP signals between mouse cortex and olfactory bulb JF bioRxiv FD Cold Spring Harbor Laboratory SP 144279 DO 10.1101/144279 A1 Parabucki, Ana A1 Lampl, Ilan YR 2017 UL http://biorxiv.org/content/early/2017/05/31/144279.abstract AB Local field potentials are an important measure of brain activity and have been used to address various mechanistic and behavioral questions. We revealed a prominent whisker evoked local field potential signal in the olfactory bulb and investigated its physiology. This signal, dependent on barrel cortex activation and highly correlated with its local activity, represented a pure volume conductance signal that was sourced back to the activity in the ventro-lateral orbitofrontal cortex, located a few millimeters away. Thus, we suggest that special care should be taken when acquiring and interpreting LFP data.
