Theta band oscillation and synchrony in the hippocampal formation and associated structures: the case for its role in sensorimotor integration

Vestibular stimulation enhances hippocampal long-term potentiation via activation of cholinergic septohippocampal cells

“…Besides participating in formation of spatial memory [3,88,89], septohippocampal cholinergic neurons may also be important for sensorimotor processing in which activation of the vestibular system provides a sensory signal to assist in motor planning [90]. A number of studies have demonstrated that vestibular stimulation can improve cognition in humans (reviewed in [91][92][93]).…”

“…However, a few experiments in which a short (<15 s) afterdischarge was evoked were included, since the magnitude of LTP (expressed at a ratio of the baseline) was similar to experiments without afterdischarge [42]. Following tetanus, AEPs were recorded at "fixed" times at 5,10,15,20,30,60,90,120,150 and 180 min. Previous data showed that LTP magnitude was not significantly different among test pulses of 1.5-2× fEPSP threshold intensity [43]; therefore, all AEPs were recorded with test pulse of 1.5× the fEPSP threshold.…”

Seizure logging: A new approach to synchronized cable-free EEG and video recordings of seizure activity in mice

“…Previously, such comparisons have relied on data from experiments with cablebased recordings from rodents, both during normal (cf. Bland and Oddie, 2001) and epileptic behavior (Moraes et al, 2005). With situation-related seizure activity, such as the handling-provoked seizures ofSynDKOmice, seizure induction can be problematic with cable-based systems.…”

Role of a neuronal small non-messenger RNA: behavioural alterations in BC1 RNA-deleted mice

“…Thus, the specific impact of BC1 RNA on exploratory behaviour can be expected to reflect expression and function of the RNA in brain areas that subserve such behaviour. Exploratory behaviour strongly depends on septal modulation of the hippocampus [7,42], and because expression of BC1 To analyse behavioural effects of deleting the BC1 gene in vivo a wide ranging test battery was conducted. With pooled data from all three lines strong effects on exploratory and anxiety related behaviour were found.…”
