EEG brain topography is not performed in all cases requiring a recording of the brain activity. Initially its main indication was to determine the presence of tumors and focal disease of the brain (including arteriovenous mal-formations and stroke), but today other imaging technologies have replaced the EEG to describe changes in brain structure. There are several neurosurgical procedures that rely on topographic EEG to localize electro-functional problems, such as epilepsy, before and during surgery. It is also appropriate when disturbances ...

Neuroimaging, meaning imaging the human brain with non-invasive techniques, is a fairly recent discipline within medicine and neuroscience. It falls into two broad categories: structural imaging and functional imaging. The former deals with the overall structure of the brain and the precise diagnosis of intracranial disease and injury. The latter is used for neurological and cognitive science research and building brain-computer interfaces. It enables, for example, the processing of sensory information coming to the brain and o ...

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 ...

Electroencephalography is the neurophysiologic measurement of the electrical activity of the brain by recording from electrodes placed on the scalp, or in the special cases on the cortex. The resulting traces are known as an electroencephalogram (EEG) and represent so-called brainwaves. This device is used to assess brain damage, epilepsy and other problems. In some jurisdictions it is used to assess brain death. EEG can ...

Alpha waves are electromagnetic oscillations in the frequency range of 8-12 Hz arising from synchronous and coherent (in phase / constructive) electrical activity of large groups of neurons in the human brain. They are also called Berger's wave in memory of the founder of EEG. Alpha waves are commonly detected by electroencephalography (EEG) or magnetoencephalography (MEG) and predominantly found to originate from the occipital lobe during periods of relaxation, with eyes closed but still awak ...

Bioelectromagnetics is the study of how electromagnetic fields interact with and influence biological processes. Common areas of investigation include the mechanism of animal migration and navigation using the geomagnetic field, studying the potential effects of man-made sources of electromagnetic fields, such as those produced by the power distribution system and mobile phones, and developing novel therapies to treat various conditions. While several treatments based on the use of magnetic fields have been reported in peer-reviewed j ...

Cyclical Alternating Pattern occurs in sleep. Characterized as periodic episodes of aroused EEG activity (more Sleep spindles and K-complexes) followed by a period of more quiet sleep. Both these periodic activities, when combined, are considered the CAP period. CAP does not occur in REM. Other related archivesEEG, K-complexes, REM, Sleep spindles, sleep

Active Sleep is a phase of sleep in neonates that appears similar to Rapid Eye Movement (REM) sleep in adults. While it depends on age, neonatal sleep is sometimes scored as Active Sleep, Quiet Sleep, and Wake. This is less specific than the classification of adult's sleep, and is often based on behavioral criteria due to the technical difficulties arising from recording EEG from the neonate. Scientists are divided on the precise relation between Active Sleep and REM sleep. Some suggest that they are similar, while others say i ...

Neurofeedback (NFB), also called neurotherapy, neurobiofeedback or EEG biofeedback, enables an individual to train brainwave activity, as measured by electrodes on the scalp, via feedback of EEG information in the form of a video display, sound or vibration. If brain activity changes in the direction desired by the therapist, a positive "reward" feedback is given to the individual, and if it regresses, either a negative feedback or no feedback is given (depending on the protocol). Rewards can be as simple as a cha ...

Zen and the Brain: Toward an Understanding of Meditation and Consciousness is a book authored by James H. Austin. First published in 1998, the book's aim is to establish links between the neurological workings of the human brain and meditation. For example Austin presents evidence from EEG scans that deep relaxed breathing reduces brain activity. The publishers described their book as a "Comprehensive text on the evidence from neuroscience that helps to clarify which brain mechanisms underlie the subjective states of Zen, and employs Zen to 'illuminate' ...

A visual evoked potential (VEP) is an evoked potential caused by sensory stimulation of a subject's visual field. Commonly-used visual stimuli are flashing lights, or checkerboards on a video screen that flicker between black on white to white on black (invert contrast). Visual evoked potentials are very useful in detecting blindness in patients that cannot communicate, such as babies or non-human animals. If repeated stimulation of the visual field causes no changes in EEG potentials, then the subject's brain is probably not r ...

Brain death is defined as a complete and irreversible cessation of brain activity. Absence of apparent brain function is not enough. Evidence of irreversibility is also required. Brain-death is often confused with the state of vegetation. Traditionally, death has been defined as the cessation of all body functions, including respiration and heartbeat. Since it became possible to revive some people after a period without respiration, heartbeat, or other visible signs of life, as well as to maintain respiration and blood f ...

The abacus system of mental calculation is a system where users mentally visualize an abacus to do calculations. No physical abacus is used; only the answers are written down. This system is being propagated in Singapore, South Korea, Thailand, Malaysia and Japan. Mental calculation is said to improve mental capability, increases speed of response, memory power and concentration power. Many veteran and prolific abacus users in China, Japan, South Korea and others who use the abacus daily, naturally tend to not use the ab ...

Oneirology is the scientific study of dreams, a relatively new field. The term comes from the Greek Oneiro which means dream. The discipline is generally agreed to have begun with the discovery by Nathaniel Kleitman and his student Eugene Aserinsky in 1955 of regular cycles in human sleep, in the sleep laboratory at the University of Chicago. A further experiment by Kleitman and William C. Dement, then another medical student, demonstrated the particular period of sleep in which electrical brain activity as ...

Benjamin Libet is a researcher in the physiology department of the University of California, San Fransisco, and is a pioneering scientist in the study of human consciousness. In the 1970's, Libet researched neural activity and sensation thresholds. His initial investigations involved determining how much activation at specific sites in the brain would trigger artificial somatic sensations, relying on routine psychophysical procedures. This work soon crossed into the realm of investigation of human consciousness; his most famous and co ...
