Short-term potentiation of miniature excitatory synaptic currents causes excitation of supraoptic neurons.

Journal of Neurophysiology, 2000
Magnocellular neurons (MCNs) of the hypothalamic supraoptic nucleus (SON) secrete vasopressin and oxytocin. With the use of whole-cell and nystatin-perforated patch recordings of MCNs in current- and voltage-clamp modes, we show that high-frequency ...

Short-term potentiation of breathing in humans.

Journal of applied physiology, 1991
The purpose of this study was to determine if the increase in ventilation induced by hypoxic stimulation of the carotid bodies (CB) persists after cessation of the stimulus in humans.

Short-term potentiation of carotid chemoreflex: an NMDAR-dependent neural integrator.

NeuroReport, 1999
Repetitive stimulation of the carotid sinus nerve (CSN) elicits a short-term potentiation (STP) of the reflex response in respiratory motor output in mammals. The input-output transformation approximates a leaky integrator with a time constant of several

Afferent and association fiber differences in short-term potentiation in piriform (olfactory) cortex of the rat.

Journal of Neurophysiology, 1990
1. The effects of low-frequency stimulus trains on synaptically evoked responses in piriform cortex pyramidal cells were studied by the use of intracellular recording techniques in an in vitro slice preparation.

Hippocampal long- and short-term potentiation is modulated by adrenalectomy and corticosterone.

Neuroendocrinology, 1996
The effect of acute corticosterone (CORT) treatment on elaboration of long-term potentiation (LTP) and short-term potentiation (STP) in intact and adrenalectomized rats was investigated.

Short-term potentiation of ventilation after different levels of hypoxia.

Journal of applied physiology, 1999
Short-term potentiation of ventilation (VSTP) may be observed in healthy subjects on sudden termination of an hypoxic stimulus. We hypothesized that the level of hypoxia preceding normoxia would modify the duration and magnitude of the ensuing ...

Tetanic stimulation induces short-term potentiation of inhibitory synaptic activity in the rostral nucleus of the solitary tract.

Journal of Neurophysiology, 1998
Whole cell recordings from neurons in the rostral nucleus of the solitary tract (rNST) were made to explore the effect of high-frequency tetanic stimulation on inhibitory postsynaptic potentials (IPSPs).

Effect of hypoxic sensitivity on decay of respiratory short-term potentiation.

Chest, 1995
In normal conscious humans, when a brief hypoxic ventilatory stimulus is followed immediately by breathing 100% O2, ventilation during hyperoxia gradually declines to baseline prehypoxic levels without an undershoot.

Cholinergic mechanisms and short-term potentiation.

Ciba Foundation symposium, 1977
Acutely prepared rabbits were used to study, electrophysiologically, tetanic and post-tetanic potentiation of the pathway from the medial septal region to hippocampal field CA1. It was found that tetanic potentiation, evoked by short stimulus trains, was

Mitragyna speciosa Korth standardized methanol extract induced short-term potentiation of CA1 subfield in rat hippocampal slices

, 2012
Mitragyna speciosa Korth or ketum or kratom has long been used by local people in Thailand and Malaysia to treat various types of diseases and to boost energy. There is lack of information available on the effect of M.
