abstract = {Ongoing neuronal oscillations in vivo exhibit non-random
amplitude fluctuations as reflected in a slow decay of
temporal auto-correlations that persist for tens of seconds.
Interestingly, the decay of auto-correlations is altered in
several brain-related disorders, including epilepsy,
depression and Alzheimer's disease, suggesting that the
temporal structure of oscillations depends on intact
neuronal networks in the brain. Whether structured amplitude
modulation occurs only in the intact brain or whether
isolated neuronal networks can also give rise to amplitude
modulation with a slow decay is not known. Here, we examined
the temporal structure of cholinergic fast network
oscillations in acute hippocampal slices. For the first
time, we show that a slow decay of temporal correlations can
emerge from synchronized activity in isolated hippocampal
networks from mice, and is maximal at intermediate
concentrations of the cholinergic agonist carbachol. Using
zolpidem, a positive allosteric modulator of GABA(A)
receptor function, we found that increased inhibition leads
to longer oscillation bursts and more persistent temporal
correlations. In addition, we asked if these findings were
unique for mouse hippocampus, and we therefore analysed
cholinergic fast network oscillations in rat prefrontal
cortex slices. We observed significant temporal
correlations, which were similar in strength to those found
in mouse hippocampus and human cortex. Taken together, our
data indicate that fast network oscillations with temporal
correlations can be induced in isolated networks in vitro in
different species and brain areas, and therefore may serve
as model systems to investigate how altered temporal
correlations in disease may be rescued with pharmacology.},
