Learning, or more generally, plasticity may be studied using cultured networks of rat cortical neurons on multi electrode arrays. Several protocols have been proposed to affect connectivity in such networks. One of these protocols, proposed by Shahaf and Marom, aimed to train the input-output relationship of a selected connection in a network using slow electrical stimuli. Although the results ...

The protocol used for intermittent photic stimulation (IPS) may determine the likelihood of evoking a photoparoxysmal response (PPR). One-hundred and thirty-five electroencephalograms (EEGs) presenting PPRs, from 125 patients were studied in order to identify the most effective stimulation frequency to evoke a PPR and the effects of repetition of IPS on the occurrence of a PPR. Two stimulation ...

We propose a transformer building a silent self-stabilizing with service guarantee 1-hop clustering protocol T P of an input silent self-stabilizing 1-hop clustering protocol P. From an arbitrary configuration, T P reaches a safe configuration in at most 3 rounds, where the following useful minimal service is provided: “each node belongs to a 1-hop cluster having an effective leader”. During st...

OBJECTIVE To compare the two GnRH-a protocols (long GnRH-a protocol and short GnRH-a protocol) for ovarian stimulation in IVF/ICSI cycles in patients of various age ranges. METHODS A total of 5662 IVF-ET/ICSI cycles from 2010 to 2013 were retrospectively identified. The cycles were divided into two groups: a long protocol group and short protocol group. In each group, the patients were divide...

A protocol for programmed ventricular stimulation is described in which the effect of increasing stimulation current on ventricular refractoriness and arrhythmia induction was specifically examined. The protocol was evaluated prospectively in 70 patients undergoing electrophysiological study for documented or suspected ventricular arrhythmias. Programmed electrical stimulation was performed at ...

We used the perforated-patch technique to examine the relationship between Ca2+ entry and exocytosis of large dense-cored vesicles in bovine adrenal chromaffin cells. Exocytosis evoked by single-step depolarizations was monitored by capacitance detection. Ca2+ entry was varied by changing external calcium concentration, stepping to different test potentials, depolarizing for different durations...

background: based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (fsh) and luteinizing hormone (lh) put on their main effects on the granulosa and theca cells. lh is essential for androgens production. androgens are used for estradiol production by granulosa cells. profound suppression of lh concentrations in some normogonadotropic patients can cau...

In this issue of Neuron, Huang et al. show that a version of the classic theta burst stimulation protocol used to induce LTP/LTD in brain slices can be adapted to a transcranial magnetic stimulation (TMS) protocol to rapidly produce long lasting (up to an hour), reversible effects on motor cortex physiology and behavior. These results may have important implications for the development of clini...

objective: the objective of this study is to compare rates of pregnancy and ivf parameters in subjects who were stimulated with follicle stimulating hormone (fsh) plus either recombinant human luteinizing hormone (r-lh) or human menopausal gonadotropins (hmg), in long gonadotropin releasing hormone (gnrh) agonist ivf protocols. materials and methods: this is a cohort study of patients undergoin...
