[ 1 ] - An Emotion Recognition Approach based on Wavelet Transform and Second-Order Difference Plot of ECG

Emotion, as a psychophysiological state, plays an important role in human communications and daily life. Emotion studies related to the physiological signals are recently the subject of many researches. In This study a hybrid feature based approach was proposed to examine affective states. To this effect, Electrocardiogram (ECG) signals of 47 students were recorded using pictorial emotion elici...

[ 2 ] - Power Spectral Density Analysis of Purkinje Cell Tonic and Burst Firing Patterns From a Rat Model of Ataxia and Riluzole Treated

Introduction: Purkinje Cell (PC) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. Riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. Here, the spectral analysis of PCs firing in control, 3-acety...

[ 3 ] - Contribution of Somatic and Dendritic SK Channels in the Firing Rate of Deep Cerebellar Nuclei: Implication in Cerebellar Ataxia

Introduction: Loss of inhibitory output from Purkinje cells leads to hyperexcitability of the Deep Cerebellar Nuclei (DCN), which results in cerebellar ataxia. Also, inhibition of small-conductancecalcium-activated potassium (SK) channel increases firing rate  f DCN, which could cause cerebellar ataxia. Therefore, SK channel activators can be effective in reducing the symptoms of this disease, ...

[ 4 ] - تحلیل آنتروپی سیگنال نرخ ضربان قلب در هنگام تفکر خلاق

زمینه: خلاقیت را می‌توان یکی از مهم‌ترین رفتارهای شناختی نامید که شکوفایی جوامع و تسلط بر جنبه‌های مختلف زندگی پیرامون در سایه‌ی توجه به آن امکانپذیر است. تا کنون در چندین مطالعه اثر فعالیت‌های خلاقانه بر روی مغز مورد بررسی قرار گرفته است. اما تغییرات سیستم خودمختار در این گونه فعالیت‌ها چندان بررسی نشده است. در این مطالعه با تکیه بر روش‌‌های مبتنی بر استخراج ویژگی‌های آشوبی و غیر خطی از سیگنال...

[ 5 ] - A Predictive Model for Emotion Recognition Based on Individual Characteristics and Autonomic Changes

Introduction: The importance of individual differences in the problem of emotion recognition has been repeatedly stated in the studies. The major concentration of this study was the prediction of heart rate variability (HRV) changes due to affective stimuli from the subject characteristics. These features were age (A), gender (G), linguality (L), and sleep (S) information. In addition, the most...
