Heat-treated and untreated sera from rats immune to Strongyloides ratti are capable of arming both immune and non-immune macrophages and eosinophils in vitro. These cells are capable of killing larvae of the parasite. Electron microscopy has indicated multi-point attachment of the cells to the epicuticular transverse grooves of the larvae within 4 and 24 h(More)
Functional near-infrared spectroscopy (fNIRS) is an optical imaging technique that allows real-time monitoring of the oxy-hemoglobin (oxy-Hb) and deoxy-hemo-globin (deoxy-Hb) levels in brain tissues in a noninvasive fashion [1,4,6]. The characteristic absorption spectra of oxy-Hb and deoxy-Hb recorded on the scalp can be used to detect the oxygen demands of(More)
This study provides a computational scheme to decode intentional arm movement direction using optical imaging of the motor cortex for future implementation on a neuro-prosthetic device that enables physically disabled patients to navigate a wheelchair using brain-derived signals. To this end, we developed a signal-processing algorithm for detecting movement(More)
This study aims to identify the acute effects of physical exercise on specific cognitive functions immediately following an increase in cardiovascular activity. Stair-climbing exercise is used to increase the cardiovascular output of human subjects. The color-naming Stroop Test was used to identify the cognitive improvements in executive function with(More)
A theoretical model of social empathic emotion is derived based on the principles of survival by extending the maximization of self-gains to include others as an extended-self. This extended-self model of optimization for survival provides the computational mechanisms in the optimization process to maximize self-gains without minimizing the gains (or(More)
The present study derives the evolution of social emotions by inclusion of other-regarding concerns from the non-social emotions of self-regarding concerns. Emotional processing is a self-discovered error-correction feedback process in which computations are involved to assess the accuracy of the internal brain-generated predictions with respect to the(More)
Assessment of long-term studies on the carcinogenic potential of certain environmental agents has indicated that all of the following appear to activate and/or promote the inherent tumors of the host strains of the animals used irrespective of the extent of additional immunological modulation accompanying the agents: tobacco smoke inhalation, the(More)
This study provides an experimental confirmation of the proportionality hypothesis predicted by the theoretical model of emotion [1,2] based on EEG recordings. The computational emotional model [1,2] proposed that emotion is an error-feedback signal provided to an organism to estimate the accuracy of the internal brain prediction of external world. It is(More)
