Event and apparent horizons are key diagnostics for the presence and properties of black holes. In this article I review numerical algorithms and codes for finding event and apparent horizons in numerically-computed spacetimes, focusing on calculations done using the 3 + 1 ADM formalism. The event horizon of an asymptotically-flat spacetime is the boundary between those events from which a futu...

Background and Aim: The aim of the present study was to investigate the effect of Garlic extract on cortical spreading depression (CSD) specifications as underlying mechanism of aura and subsequent pain in migraine in rats' neocortical slices. Materials and Methods: In this experimental study, CSD was induced in rats' somatosensory cortical slices using two models as follows: first, after KCl m...

Abstract of spoken word recognition is proposed. This model is particularly concerned with extraction of cues from the signal leading to a specification of a word in terms of bundles of distinctive features, which are assumed to be the building blocks of words. In the model proposed, auditory input is chunked into a set of successive time slices. It is assumed that the derivation of the underly...

Objective(s) Bupropion is an atypical antidepressant that is widely used in smoke cessation under FDA approval. The study of synaptic effects of bupropion can help to finding out its mechanism(s) for stopping nicotine dependence. In this study the effects of perinatal bupropion on the population spike (PS) amplitude of neonates were investigated. Materials and Methods Hippocampal slices were...
