The principle of “Mirror Neurons System (MNS)” emphasizes that, the brain mechanism is not only able to acknowledge the actions but as well be able to imitate that actions from an observers own perspective. Thus, the concept of MNS also substantiates the development of motor related cortical activity in the human brain, since the neurons fires when a person observes another's action as though the...
EEG signals collected non-invasively from the cerebral cortex are often contaminated with signals from eye movement [EOG], which considerably degrades the reliability of extracting proper information from the actual signals. This study attempts a two-step algorithm to obtain an EOG artifact free EEG signal with best performance index. Two types of decomposing methods namely Discrete Wavelet Transform...
Man-machine interfacing holds the key for developing assistive technology. Moving towards this direction, here we present a simple and novel design that uses photoplethysmography for interfacing application. The intent behind this development was to aid people having disabilities with novel rehabilitation tool. Present research, illustrates a set of pilot experiments that successfully demonstrates...
Human brain behaves differently with the different task conditions presented. This is due to the cognitive load that each task condition imposes. In this article we are looking for the difference in cognitive load that each subject faces when subjected to different task conditions. We will try to differentiate the two category of subjects i.e. alcoholic and controls on the basis of the cognitive demand...
Human brain is still known to be the ultimate and the best machine in its ability for decision making. Researchers are in a constant process of understanding and duplicating the functions of the brain; though these efforts are still in infancy. In this present study, we are trying to analyze the processing of different perceptual tasks given to alcoholic and control subjects. The aim is to correlate...
Manual classification of ictal and non-ictal activities continues to be very perplexing even for any experienced neurophysiologist. Mostly due of the presence of considerable heterogeneity in the seizure patterns. Extensive research efforts have gone in solving this issue. But, the shortcomings and complexity of the deployed methods till date have been noteworthy to realize their practical applications...
The classification of normal and ailing brain activities through visual inspection proves to be very challenging even for any experienced neurologist. The case is even worse for detection of heterogeneous anomalies like epileptic seizures. Authors have presented robust expert system design for classification of epileptic seizures automatically with an improvement over the existing systems. The developed...
An Image is a representation of the information in visual form. The quality of the image acquired depends greatly on the type of image acquisition systems. Sometimes these systems fail to give the good results and we need to process the image to get the desired information. In this paper we will discuss the Multi-focus images and their fusion. A multi-focus image is the result of the inability of...
