(1-4) The examiner briskly rotates the patient’s head while having the patient fixate on a target, usually the examiner’s nose. The concept of credit impulse was first introduced by Deutsche Bank economist Michael Biggs, in November 2008. Impulsivity, or impulsive behavior, is broadly defined as actions without foresight that are poorly conceived, prematurely expressed, unnecessarily risky, and inappropriate to the situation. Communication Technology. The meaning of impulse. However, there is little consensus regarding the definition or clinical characteristics of an "impulsive" attempt. ) Impulse control disorders are pervasive and often life long manifestations of disabling behavioral patterns. Most synapses are chemical; these synapses communicate using chemical messengers. An impelling force; an impetus. Upon stimulation, they will either be stimulated, inhibited, or modulated in some way.
