results the mean ± sd of the clonic seizure threshold was 61.84 ± 8.53 in the group that received estradiol, while it was 71.70 ± 10.85 in the control group, 64.69 ± 3.23 in rats with laparotomy without removing the ovaries, 51.30 ± 6.84 in rats with laparotomy and removing the ovaries, 52.7 ± 7.18 in ovariectomized rats that received sesame oil as vehicle, and 59.2 ± 4.91, in the soy groups. t...

Thresholds to anodal make, anodal break, cathodal make and cathodal break have been studied throughout the cardiac cycle in 13 dogs under pentobarbital anesthesia. Unipolar direct current pulses were applied through epicardial pacemaker electrodes to the left ventricle. Make and break responses were separated by letting the break and make occur in the refractory periods of the following and pre...

We describe evidence consistent with the proposal that the visual system contains a parallel array of size-tuned mechanisms sensitive to orientation texture-defined (OTD) form, and propose that the relative activity of these mechanisms determines spatial frequency discrimination threshold for OTD gratings. Using a pattern of short lines we measured spatial frequency discrimination thresholds fo...

The objective of this study was to determine whether impaired upper airway (UA) mucosal sensation contributes to altered swallowing function in obstructive sleep apnea (OSA). We determined UA two-point discrimination threshold (2PDT) and vibratory sensation threshold (VST) in 15 men with untreated OSA and 9 nonapneic controls (CL). We then assessed swallowing responses to oropharyngeal fluid bo...

Abstract For the progress of artificial neural networks, imitation multiple biological functions is indispensable for processing more tasks in a complex working environment. Memristors, which possess these advantages such as uniformity, high switching speed, and smaller device scale, are better candidates compared to conventional complementary metal–oxide–semiconductor (CMOS) technology network...

An overview of relationships between psychophysical measures of olfactory function and reproductive neuroendocrine processes is presented. Human studies are emphasized, and the influences of gender, menstrual cycle phase, pregnancy, and injected gonadal hormones upon olfactory perception are discussed in detail. Key Words-Pregnancy, olfactory threshold, odor preferences, hormones, estrous cycle...

Spectrum sensing enables detecting opportunities in licensed bands in order to access unused portions of the licensed spectrum. In this paper we propose two low complexity detectors based on a combination of two well-known and complementary signal detection mechanisms: energy detection and mono-cycle detection, which exploits cyclostationarity property of the signals. In the first algorithm the...
