BACKGROUND The import of the cavum variation and its prevalence rate in healthy individuals is still not clear, likewise in neurologically diseased patients. PURPOSE To evaluate the frequency and pattern of caval variations in neurologically diseased patients. MATERIAL AND METHODS The presence or absence of the cavum septum pellucidum (CSP), cavum vergae (CV), or cavum velum interpositum (C...

Automatic recognition of human emotion has become an interesting topic among brain-computer interface (BCI) researchers. Emotion is one the most fundamental features a subject. With proper analysis emotion, inner state subject can be assessed directly. The brain response competently represented by electroencephalography (EEG). selection potential in EEG related to very important task for develo...

In this paper, we propose an improved filter selection method using Welch’s t-test based on discriminative filter bank common spatial pattern (DFBCSP). Existing DFBCSP used the Fisher ratio in order to find out discriminative filters. However, the Fisher ratio can be used to know only comparative value of distinguishability but may not become a meaningful criterion to reject null hypothesis. As...

iranian traditional cities were created with a system based on experiments and gradual establishment of society through time. qajar era is especially important in iranian art history. until mid qajar era, iranian cities’s architecture mainly took benefit of its common traditional architecture that is already seen in most desert-surrounding cities. till this era, there was not any connection bet...

PURPOSE To develop perimetric stimuli for which sensitivities are more resistant to reduced retinal illumination than current clinical perimeters. METHODS Fifty-four people free of eye disease were dilated and tested monocularly. For each test, retinal illumination was attenuated with neutral density (ND) filters, and a standard adaptation model was fit to derive mean and SEM for the adaptati...

This paper proposes a noise robust talker localization method based on weighted CSP (Cross-power Spectrum Phase) analysis with an average speech spectrum as the pre-process of microphone array steering. The proposed method consists of two processes. First, CSP coefficients are weighted by analysis weight coefficients based on an average speech spectrum, which is trained with speech database, in...

the present study aims to simulate the spatial pattern of land use change in lisar protected area,iran. land cover maps for 1989, 2000, and 2007 were depicted using tm, etm+, and irs liss-iii images ofthe area at stake. images were classified using a merge of unsupervised and supervised classification. camarkov model was used to predict land cover maps as a top-down approach in investigating la...

The presence of cavum septum pellucidum (CSP) has been reported to be a neurodevelopmental marker of psychopathy. We scanned 26 violent offenders and 25 controls; 2 offenders and 2 controls had CSP (8% in both groups). Thus, the presence of CSP is not a common or a unique feature of antisocial personality disorder or psychopathy.

The cholinergic neurons in the laterodorsal tegmental nucleus (LDT) play a crucial role in the regulation of rapid eye movement (REM) sleep. Because penile erection occurs during REM sleep, the involvement of the LDT in penile erection was examined in unanesthetized head-restrained rats. To detect penile erection, corpus spongiosum of the penis (CSP) pressure was measured through a telemetric d...

In some tasks that require sustained attention, vigilance levels of the operator might become very important. EEG has been proved very effective for measuring vigilance. However, many difficulties exist in this field such as how to label the EEG data, how to remove the noise from the EEG data and so on. In this paper, we introduce a very useful signal transform method, Common Spatial Pattern, t...
