Brain fingerprinting is a technique that measures recognition of familiar stimuli by measuring electrical brain wave responses to words, phrases, or pictures that are presented on a computer screen. Brain fingerprinting was invented by Dr. Lawrence Farwell. The theory is that the suspect's reaction to the details of an event or activity will reflect if the suspect had prior knowledge of the event or activity. This test uses the Memory and Encoding Related Multifaceted Electroencephalographic Response to detect familiarity reaction. It ...

Some believe brain fingerprinting needs far more refinement before its use becomes widespread and court cases are decided on its evidence. A large proportion of the scientific community believes that this new test will have the same limitations as the older polygraph test. Several studies have shown it is possible to control electroencephalographic response in much the same way as it is possible to fool a polygraph test; however, a higher level of training and discipline is required. Neither American or Euro ...

Sleep - Methodology. Before advances in the fields of neurology, neuroscience, electronics and genetics were made, scientists studied the behavioral characteristics of sleep, such as its pattern, depth and varying frequency. In more recent times, the electrical impulses generated by the brain are recorded using a device called an electroencephalograph (EEG), and individual genes relating to sleep-related brain function, such as the circadian rhythm, are isolated. Molecular biology, medical science and epidemiology all play an ...

As a young man Walter was greatly influenced by the work of the famous Russian physiologist Ivan Pavlov. He visited the lab of Hans Berger, who invented the electroencephalograph, or EEG machine, for measuring electrical activity in the brain. Walter produced his own versions of Berger's machine with improved capabilities, which allowed it to detect a variety of brain wave types ranging from the h ...

Biofeedback

A scientific technique to tune into and consciously control bodily functions through the use of EEG (electroencephalographic) feedback instruments to monitor brain waves and skin resistance with the goal of modification of brain waves. and feeds that information back to the user.

Participants can learn to control heart rates or generate brain wave activity (alpha, beta, and delta) at will to induce altered states of consciousness. Enhances the capacity for relaxation and/or inducing meditative states and physiological control similar to that in yoga and Zen.

Meditation like yoga originated in Vedic Hinduism many centuries ago, it was much later adopted into a wide variety of practices of religious and non-religious formats which emphasize mental activity or quiesscence. The English word comes from the Latin meditatio, which originally indicated every type of physical or intellectual exercise, but which later could perhaps be better translated as "contemplation." This usage is found in Christian spirituality, for example, when one "meditates" on the sufferings of Christ; as w ...

In the recent years there has been a growing interest within the medical community to study the physiological effects of meditation (Venkatesh et al., 1997; Peng et al., 1999; Lazar et al., 2000; Carlson et.al, 2001). Many concepts of meditation have been applied to clinical settings in order to measure its effect on somatic motor function as well as cardiovascular and respiratory function. Also the hermeneutic and phenomenological aspects of meditation are areas of growing interest. Meditation has entered the mainstream of health care as a ...

Most traditions address the integration of mind, body, and spirit (this is a major theme of the Bhagavad-Gita); or that of spiritual practice with family life, work, and so on. Often, meditation is said to be incomplete if it doesn't lead to positive changes in one's daily life and attitudes. In that spirit some Zen practitioners have promoted "Zen driving," aimed at reducing road rage. Meditation is often presented not as a "free-standing" activity, but as one part of a wider spiritual tradition. Nevertheless, many meditators today d ...

These vary so much that it is difficult to venture any general comments. On one extreme there exist monks and nuns whose whole lives are ordered around meditation; on the other hand, one-minute meditations are not out of the question. Twenty or thirty minutes is probably a typical duration. Experienced meditators often find their sessions growing in length of their own accord. Observing the advice and instructions of one's spiritual teacher is generally held to be most beneficial. Many traditions stress regular practice. Accordingly, many meditators experience guilt or frustration upon failing to do so. Poss ...

The purposes for which people meditate vary almost as widely as practices. Meditation may serve simply as a means of relaxation from a busy daily routine; as a technique for cultivating mental discipline; or as a means of gaining insight into the nature of reality, or of communing with one's God. Many report improved concentration, awareness, self-discipline and equanimity through meditation. Many authorities avoid emphasizing the effects of meditation — sometimes out of modesty, sometimes for fear that the expectation of results mi ...

According to Bogart (1991) and Perez-De-Albeniz & Holmes (2000) the different techniques of meditation can be classified according to their focus. That is, whether they focus on the field or background perception and experience, also called mindfulness, or whether they focus on a preselected specific object, also called "'concentrative' meditation." There are also techniques that shift between the field and the object. Categorizing the varieties of meditation is difficult. One common way is according to religion or lineage. Of cou ...

Different spiritual traditions, and different teachers within those traditions, prescribe or suggest different physical postures for meditation. Most famous are the several cross-legged postures, including the so-called Lotus Position. For example, the Dalai Lama recommends the Seven Points of Vairocana in which the legs are crossed in either the Lotus Positon (here called the vajra position) or the other way, "Indian" or "tailor" fashion (here called the bodhisattva position) the eyes are kept open (thus affirming the ...

While meditation focuses on mental or psycho-spiritual activity, this is of course only one of several spheres of human existence; and we are social beings as well as individuals.

In the late nineteenth century, Theosophists adopted "meditation" to refer to various spiritual practices drawn from Hinduism, Buddhism, and other Eastern religions. Thus the English word "meditation" does not exclusively translate any single term or concept from the sacred languages of Asia, such as the Sanskrit dhyana, samadhi, or pranayama. (Note that whereas in Eastern religions meditation is often a central part of religious or spirtual practice, in Christianity it tends to be a ...
