The modulation of auditory event-related potentials (ERP) by attention generally results in larger amplitudes when stimuli are attended. We measured the P1-N1-P2 acoustic change complex elicited with synthetic overt (second formant, F2Δ=1000Hz) and subtle (F2Δ=100Hz) diphthongs, while subjects (i) attended to the auditory stimuli, (ii) ignored the auditory stimuli and watched a film, and (iii) ...

Background: Electroretinography (ERG) is known as a diagnostic test for evaluating the performance of different layers of the retina. Its normal values maybe different in different populations. Objectives: Determining the normal values of ERG parameters in patients presenting to an ophthalmologic center in Guilan in northern Iran. Materials and Methods: Fifty-five people presenting to a teach...

The aim of the present study was to investigate the sleep promoting effect of BR-16A, a polyherbal formulation along with GABAergic drugs. Pentobarbitone-induced hypnosis test was used as an animal model to explore its role in sleep. Pentobarbitone produces quick the sleep latency (onset) and prolongation of total sleep time (duration). Seep latency and total sleep time were used as parameters ...

in the present study, the effects of intracerebroventricular (icv) injections of histamine, chlorpheniramine (h1-receptor antagonist) and ranitidine (h2-receptor antagonist) were investigated on visceral nociception induced by an intraperitoneal (ip) injection of acetic acid in rats. the latency time to the beginning of the first abdominal wall contraction (the first writhe) was recorded and th...

The efficient use of bandwidth available on an external SDRAM interface is strongly dependent on the sequence of addresses requested. On-chip memory buffers can make possible data reuse and request reordering which together ensure bandwidth on an SDRAM interface is used efficiently. This paper outlines an automated procedure for generating an application-specific memory hierarchy which exploits...

objective: resin cements, regardless of their biocompatibility, have been widely used in restorative dentistry during the recent years. these cements contain hydroxy ethyl methacrylate (hema) molecules which are claimed to penetrate into dentinal tubules and may affect dental pulp. since tooth preparation for metal ceramic restorations involves a large surface of the tooth, cytotoxicity of thes...
