abstract = {Hippocampal local field potentials (LFP) are highly related
to behavior and memory functions. It has been shown that
beta band LFP oscillations are correlated with contextual
novelty and mnemonic performance. Evidence suggests that
changes in neuromodulators, such as acetylcholine and
dopamine, during exploration in a novel environment underlie
changes in LFP. However, potential downstream mechanisms
through which neuromodulators may alter the beta band
oscillation in vivo remain to be fully understood. In this
paper, we study the role of the membrane cationic channel
TRPC4, which is modulated by various neuromodulators through
G-protein-coupled receptors, by combining shRNA-mediated
TRPC4 knockdown (KD) with LFP measurements in the CA1 region
of the hippocampus in behaving mice. We demonstrate that the
increased beta oscillation power seen in the control group
mice in a novel environment is absent in the TRPC4 KD group.
A similar loss of modulation was also seen in the low-gamma
band oscillations in the TRPC4 KD group. These results
demonstrate that TRPC4 channels are involved in the
novelty-induced modulation of beta and low-gamma
oscillations in the CA1 region.},
