In response to a published assertion to the contrary, this paper briefly reviews many studies that document remote wounding effects of ballistic pressure waves including experiments in pigs and dogs that find brain injury resulting from animal models shot in the thigh and case studies in humans that document both remote brain and spinal cord injuries ascribed to ballistic pressure waves. The au...

A measurement based formula for consciousness, C, as a function of time t, is constructed. The formula depends on identifying a natural relevant self-generated, timedependent dynamical process inherent in any entity. For human beings the relevant dynamical process identified is the ensemble of brain waves, observed in EEG measurements, that are represented in the model by their measured time de...

brain death is defined as the permanent, irreversible and concurrent loss of all brain and brain stem functions. brain death diagnosis is based on clinical criteria and it is not routine to use paraclinical studies. in some countries, electroencephalogram (eeg) is performed in all patients for the determination of brain death while there is some skepticism in relying on eeg as a confirmatory te...

EEG signals are records of nonlinear solitary waves in human brains. The waves have several types (e.g., α, β, γ, θ, δ) in response to different levels of consciousness. They are classified into two groups: Group-1 consists of complex storm-like waves (α, β, and γ); Group-2 is composed of simple quasilinear waves (θ and δ). In order to elucidate the mechanism of EEG wave formation and propagati...

  Purpose: Blast-induced traumatic brain injury (bTBI) is one of the causes of death or permanent   invalidity which can occur unexpectedly in both military and civilian populations. This study   set out to conduct a combined Eulerian-Lagrangian computational analysis of the interaction   between a single planar blast wave and a human head in order to assess the extent of intracranial   shock w...

Timely detection of unusual and/or unexpected events in natural and man-made systems has deep scientific and practical relevance. We show that the recently proposed conceptually simple and easily calculated measure of permutation entropy can be effectively used to detect qualitative and quantitative dynamical changes. We illustrate our results on two model systems as well as on clinically chara...

T N a previous communication (3), the induction •*• of sleep, accompanied by typical brain wave patterns, during hypnosis was reported and described. The present communication concerns the brain wave changes associated with hypnotic modifications of behavior less profound than alternation of sleep and waking. The significance of these changes will be discussed in terms of the function of the br...

This article reviews literature on the characteristics and possible interpretations of the event-related potential (ERP) peaks commonly identified in research. The description of each peak includes typical latencies, cortical distributions, and possible brain sources of observed activity as well as the evoking paradigms and underlying psychological processes. The review is intended to serve as ...
