readiness potential การใช้

• The readiness potential is the neural preparation for motoric responses.
• There are two phases of the readiness potential, the early phase and the late phase.
• The initial stage of the BP, or readiness potential, is an unconscious intention of, and preparation for movement.
• These potentials include the contingent negative variation ( CNV ), readiness potential, movement-related potentials ( MRPs ), and N400 potentials.
• In fact, many researchers claimed that the terminal CNV, or E wave, was in fact the readiness potential, or bereitschaftspotential.
• A related, important issue has been the question of whether all or part of the CNV corresponds to the readiness potential.
• These components are the Bereitschaftspotential ( abbreviated BP, and also known as readiness potential, abbreviated RP ) and the Contingent Negative Variation ( CNV ).

• Although it was well known that the readiness potential reliably preceded the physical action, Libet asked whether it could be recorded before the conscious intention to move.
• The BP is an index of motor preparation and is therefore also referred to as the " readiness potential ", as it is the potential for movement to occur.
• Developed in the 1980s by clinical psychologist Deborah Sunbeck, the Infinity Walk is based on studies of cognitive science, neuropsychology, and practical applications of EEG research on lateralized readiness potential.
• Benjamin Libet's results are quoted in favor of epiphenomenalism, but he believes subjects still have a " conscious veto ", since the readiness potential does not invariably lead to an action.
• For human voluntary movement the role of the SMA has been elucidated : Its activity generates the early component of the Bereitschaftspotential ( BP ) or readiness potential BP1 or BPearly.
• Libet tells when the readiness potential occurs objectively, using electrodes, but relies on the subject reporting the position of the hand of a clock to determine when the conscious decision was made.
• Libet found that the " unconscious " brain activity of the readiness potential leading up to subjects'movements began approximately half a second before the subject was aware of a conscious intention to move.
• In this case, the felt intention correlated much more closely with the " lateralized readiness potential " ( LRP ), an ERP component which measures the difference between left and right hemisphere brain activity.
• His early research with Hans Helmut Kornhuber in the mid-1960s led to the discovery of the Bereitschaftspotential ( or readiness potential ), which is a measure of neural activity in the brain that precedes voluntary movements.
• In other words, apparently conscious decisions to act were " preceded " by an unconscious buildup of electrical activity within the brain-the change in EEG signals reflecting this buildup came to be called Bereitschaftspotential or readiness potential.
• And what he found was that a subject's " readiness potential " _ the brain signal that precedes voluntary actions _ showed up about one-third of a second before the subject felt the conscious urge to act.
• The late phase is responsible for the " stimulation of the movement s direct implementation . " The early phase of the readiness potential occurs in the supplementary motor region and is involved in the generation of voluntary movement.
