内源性诱发电位的特征是由刺激发生的心理背景决定的,而不是由刺激本身的物理参数决定的(Donchin等人,1978;Hillya等人,在出版社)。这种电位是由任何刺激形式的预期刺激序列中的意外刺激产生的(Simson等人,1977;Squires等人,1977;Desmedt和Debecker,1979),或由于预期刺激的省略(Picton等人,1974;Simson等人,1976;Sutton等人,1967)。例如,如果要求受试者对一种强度的点击进行计数,而该点击只是在一系列另一种强度的点击中很少发生,则只有罕见的、意外的点击才会产生内生波形(图1)(Ritter等人,1972;Squires等人,1975;Roth等人,1976)。这些电位与顺序加工和短期记忆功能有关(Squires等人,1976),并且在不同的临床人群中被证明是异常的(Goodin等人,1978;Squires等人,1979,Pfefferbaum等人,1979)。因此,对内源性电位的产生来源进行实验分析和鉴定具有重要的临床意义和基本的神经生理学意义。
Endogenous evoked potentials are those whose characteristics are determined by the psychological context in which a stimulus occurs, rather than by the physical parameters of the stimulus itself (Donchin et al., 1978; Hillyard et al., in press). Such potentials are produced by unexpected stimuli within a sequence of expected stimuli in any stimulus modality (Simson et al., 1977; Squires et al., 1977; Desmedt and Debecker, 1979), or by the omission of an expected stimulus (Picton et al., 1974; Simson et al., 1976; Sutton et al., 1967). For example, if a subject is asked to count a click of one intensity which occurs only infrequently during a series of clicks of another intensity, only the rare, unexpectedclick produces endogenous wave forms (Fig. 1) (Ritter et al., 1972; Squires et al., 1975; Roth et al., 1976). These potentials have been associated with sequential processing and short-term memory functions (Squires et al., 1976), and have been shown to be abnormal in various clinical populations (Goodin et al., 1978; Squires et al., 1979, Pfefferbaum et al., 1979). Thus, experimental analyses and identification of the generator sources of endogenous potentials would be of clinical importance as well as of basic neurophysiological interest.
