Behavioural and neuroscience studies have shown that observing objects activates affordances, evoking motor responses. The aim of the present study is twofold. First, we intend to investigate whether children are sensitive to the distinction between neutral/graspable (affordances) and dangerous objects. Second, we aim to verify whether children's responses are modulated also by the agent who is interacting with the objects (human hand contrasted with robot hand, and male hand contrasted to female hand). We conducted an experiment on school-age children using a priming paradigm: a prime given by a hand or a control object was followed by graspable or dangerous objects. Children were required to categorize them into artefacts or natural objects by pressing two keys on a keyboard. Our results clearly showed that children are able to distinguish between neutral and dangerous objects: the latter produced an interference effect. In addition, we demonstrated that children are sensitive to the difference between actions performed by biological and non-biological agents: responses were faster when the prime was a grasping hand of a human compared to control stimuli. Results were interpreted in terms of gradient of vulnerability (female hand induced the most inhibition, while robot hand induced the least one) and of motor resonance (resonance is higher when the similarity between the hand prime and the participant's hand is higher).

Statistical Approaches for the Analysis of Dependency Among Neurons Under Noise Gençağa, Deniz; Ayan, Sevgi Şengül; Farnoudkia, Hajar; Okuyucu, Serdar (MDPI AG, 2020-3-28) Neuronal noise is a major factor affecting the communication between coupled neurons. In this work, we propose a statistical toolset to infer the coupling between two neurons under noise. We estimate these statistical dependencies from data which are generated by a coupled Hodgkin–Huxley (HH) model with additive noise. To infer the coupling using observation data, we employ copulas and information-theoretic quantities, such as the mutual information (MI) and the transfer entropy (TE). Copulas and MI between...
Eş zamanlı gerçekleştirilen bilişsel ve motor görevin postür kontrolü üzerine etkisi Babajimopoulos, Zeren; Yılmaz, Uğur; Arpınar Avşar, Pınar; Kirazcı, Sadettin (2018-11-03) Amaç:Bu çalışmanın amacı farklı zorlukta postural motor görev sırasında eş zamanlı olarak gerçekleştirilen bilişsel görevin postür kontrolü üzerine etkisinin incelenmesidir. Yöntem:19 gönüllü katılımcı (yaş:23±6 yıl, boy:171.7± cm, v.ağırlığı:71.1± kg) 1 dk boyunca üç farklı zorluk düzeyinde bilişsel görev altında, kuvvet platformu üzerinde ayakta sakin duruş (QS) ve istemli postural salınım (VS) hareketi yapmaları istenmiştir. Bilişsel görev işitsel olarak kendilerine ardışık olarak sunulan basit aritmetik...
Investigating pain perception in somatosensory cortex for healthy and fibromyalgia patient populations by using fNIRS Eken, Aykut; Gökçay, Didem; Kara, Murat; Department of Medical Informatics (2016) In this study, we investigated the difference in hemodynamic responses between fibromyalgia (FM) and healthy controls via functional near infrared spectroscopy (fNIRS) during application of painful stimulus and transcutaneous electrical nerve stimulation (TENS). We collected several clinical data (pain threshold, Beck Depression Inventory (BDI) score, Fibromyalgia Impact Questionnaire (FIQ) score, pain ratings) before and during the experiment. After data collection, we analyzed it using general linear mode...
Towards linking affordances with mirror/canonical neurons Şahin, Erol (2009-09-16) The notion of affordances is often directly linked with studies on mirror and canonical neurons as well as studies that try to relate language. In our previous work, we had developed a formalization for the leaming, perception and use of affordances in autonomous robots. In this paper, we will present ideas on how this formatization can be used as a base to link affordances with mirror/canonical neuron studies. Specifically, we will review the studies on mirror and canonical neurons as well as studies on mo...
Estimation of nonlinear neural source interactions via sliced bicoherence Özkurt, Tolga Esat (2016-09-01) Neural oscillations and their spatiotemporal interactions are of interest for the description of brain mechanisms. This study offers a novel third order spectral coupling measure named "sliced bicoherence". It is the diagonal slice of cross-bicoherence allowing an efficient quantification of the nonlinear interactions between neural sources. Our methodology comprises an indirect estimation method, a parametric confidence level formula and a subtracted version for robustness to volume conduction. The methodo...
