چکیده

Mitchell et al. (2008) demonstrated that corpus-extracted models of semantic knowledge can predict neural activation patterns recorded using fMRI. This could be a very powerful technique for evaluating conceptual models extracted from corpora; however, fMRI is expensive and imposes strong constraints on data collection. Following on experiments that demonstrated that EEG activation patterns encode enough information to discriminate broad conceptual categories, we show that corpus-based semantic representations can predict EEG activation patterns with significant accuracy, and we evaluate the relative performance of different corpus-models on this task.

Stress and Perception of Emotional Stimuli: Long-term Stress Rewiring the Brain

Introduction: Long-term stressful situations can drastically influence one’s mental life. However, the effect of mental stress on recognition of emotional stimuli needs to be explored. In this study, recognition of emotional stimuli in a stressful situation was investigated. Four emotional conditions, including positive and negative states in both low and high levels of arousal were analy...

Meaningfulness of Religious Language in the Light of Conceptual Metaphorical Use of Image Schema: A Cognitive Semantic Approach

According to modern religious studies, religions are rooted in certain metaphorical representations, so they are metaphorical in nature. This article aims to show, first, how conceptual metaphors employ image schemas to make our language meaningful, and then to assert that image-schematic structure of religious expressions, by which religious metaphors conceptualize abstract meanings, is the ba...

Measuring out the relation between formal and conceptual semantics∗

In this paper, we argue that contemporary approaches of constructionalist syntax in which there is no generative lexicon provide an interface between formal and conceptual semantics with which the gap between formal and conceptual semantics can be bridged. We introduce the framework with the discussion of formal and conceptual aspects of meaning in German spatial denominal prefixand particle ve...

Visual stimulus-dependent changes in interhemispheric EEG coherence in ferrets.

In recent years, the analysis of the coherence between signals recorded from the scalp [electroencephalographic (EEG) coherence] has been used to assess the functional properties of cortico-cortical connections, both in animal models and in humans. However, the experimental validation of this technique is still scarce. Therefore we applied it to the study of the callosal connections between the...

Real Time Driver’s Drowsiness Detection by Processing the EEG Signals Stimulated with External Flickering Light

The objective of this study is development of driver’s sleepiness using Visually Evoked Potentials (VEP). VEP computed from EEG signals from the visual cortex. We use the Steady State VEPs (SSVEPs) that are one of the most important EEG signals used in human computer interface systems. SSVEP is a response to visual stimuli presented. We present a classification method to discriminate between...
