Endogenous histamine facilitates long-term potentiation in the hippocampus during walking

T Luo, LS Leung - Journal of Neuroscience, 2010 - Soc Neuroscience
Long-term potentiation (LTP) in hippocampal CA1 depends on the behavioral state of LTP
induction. We hypothesize that histaminergic activity in the septohippocampal system, which …

Cholinergic activity enhances hippocampal long-term potentiation in CA1 during walking in rats

LS Leung, B Shen, N Rajakumar, J Ma - Journal of Neuroscience, 2003 - Soc Neuroscience
Long-term potentiation (LTP) at the basal-dendritic synapses of CA1 pyramidal cells was
induced by a single 200 Hz stimulation train (0.5-1 sec duration) in freely behaving rats …

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

SK Tai, LS Leung - Behavioural brain research, 2012 - Elsevier
Vestibular stimulation induced acetylcholine release in the hippocampus, and acetylcholine
is known to facilitate long-term potentiation (LTP) in the hippocampus. Thus, we hypothesize …

(R)alphamethylhistamine Suppresses Inhibitory Neurotransmission in Hippocampal CA 1 Pyramidal Neurons Counteracting PropofolInduced Amnesia in Rats

WW Li, LZ Cheng, Z Zou, ML Tian… - CNS Neuroscience …, 2014 - Wiley Online Library
Background Propofol is a shortacting, intravenous general anesthetic that is widely used in
clinical practice for short procedures; however, it causes depressed cognitive function for …

Chewing rescues stress-suppressed hippocampal long-term potentiation via activation of histamine H1 receptor

Y Ono, T Kataoka, S Miyake, K Sasaguri, S Sato… - Neuroscience …, 2009 - Elsevier
We have previously found in rats that chewing, an active behavioral strategy to cope with a
stressful situation, rescues long-term potentiation (LTP) in the hippocampus through …

Cholinergic modulation of hippocampal CA1 basal-dendritic long-term potentiation

S Doralp, LS Leung - Neurobiology of learning and memory, 2008 - Elsevier
Extensive research suggests that long-term potentiation (LTP) may serve as a cellular
mechanism for memory and that alterations in synaptic plasticity may underlie the gross …

Histamine innervation and activation of septohippocampal GABAergic neurones: involvement of local ACh release

C Xu, KA Michelsen, M Wu, E Morozova… - The Journal of …, 2004 - Wiley Online Library
Recent studies indicate that the histaminergic system, which is critical for wakefulness, also
influences learning and memory by interacting with cholinergic systems in the brain …

Histaminergic modulation of synaptic plasticity in area CA1 of rat hippocampal slices

RE Brown, NB Fedorov, HI Haas, KG Reyman - Neuropharmacology, 1995 - Elsevier
The effects of histamine on baseline synaptic transmission and long-term potentiation (LTP)
were investigated in the CA1 region of rat hippocampal slices. Bath applied histamine …

Cognitive enhancers and hippocampal long-term potentiation in vitro

S Kaneko, T Maeda, M Satoh - Behavioural brain research, 1997 - Elsevier
We review our works on the pharmacological modulation of long-term potentiation (LTP) at
guinea pig hippocampal mossy fiber-CA3 synapses in vitro. The magnitude of tetanus …

Ventral hippocampal histamine increases the frequency of evoked theta rhythm but produces anxiolytic-like effects in the elevated plus maze

M Yeung, D Treit, CT Dickson - Neuropharmacology, 2016 - Elsevier
The neurobiological underpinnings of anxiety are of paramount importance to the
development of effective therapeutic treatments. To date, there is considerable …
