Introduction: Direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. We compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (LFP) and LFPspike signals, respectively. Methods: Signals recorded from MT area of a macaque’s brain was used in a simulation ...

Based on psychophysiological research, coherent heart-brain interaction can change afferent cardiac signal pattern sent to the brain. Accordingly, the present study aimed at facilitating the emotion-cognition interaction through HeartMath Institute self-regulated emotional techniques to investigate the efficacy of heart-brain coherence on reading anxiety reduction that significantly enhances at...

Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...

An Electroencephalogram (EEG) is produced as a consequence of the electrical voltage neurons in brain. The EEG signal crucial for detecting brain activity and attitude. Because this has very low amplitude, it easily corrupted by different artefacts. study analysis signals presence these artifacts challenging task. ECG, EOG, EMG, motion are popular that induce disturbance to signal. This survey ...

background: noise pollution is one of the most harmful ambiance disturbances. it may cause many deficits in ability and activity of persons in the urban and industrial areas. it also may cause many kinds of psychopathies. therefore, it is very important to measure the risk of this pollution in different area. methods: this study was conducted in the department of medical physics and biomedical ...

introduction: interhemispheric transmission of signal is done by corpus callosum (cc) as the largest fiber tract in brain. cc comprised 5 segments of rostrum, genu, body, isthmus, and splenium. contradictory reports exist about sexual dimorphism of cc. we designed this study to assess probable sexual differences of cc and its different parts in men and women. methods: we analyzed magnetic reson...

The divalent cation zinc is an integral requirement for optimal cellular processes, whereby it contributes to the function of over 300 enzymes, regulates intracellular signal transduction, and contributes to efficient synaptic transmission in the central nervous system. Given the critical role of zinc in a breadth of cellular processes, its cellular distribution and local tissue level concentra...

This brief paper provides an introduction to the area of brain signal processing, and also serves as an introductory presentation for the special session entitled Advanced Signal Processing of Brain Signals: Methods and Applications at APSIPA 2010. Several topics related to the processing of brain signals are discussed: preprocessing, inverse modeling (a.k.a. source modeling), and signal decodi...

Our perceptions, sensations, emotions and memories rely on the approximately 80 billion neurons we have in our brain. You may wonder, nevertheless, if this number is actually too large, too small or barely enough. Is it the "billions" that makes us special? Or is there more to it than just a number, some neural mechanism that we have not yet envisioned? Cognitive Neuroscience has greatly advanc...
