本文探讨偏头痛患者（诊断根据国际头痛协会标准，1988年）的空间和时间处理，使用心理物理测试，测量空间和时间的反应。这些测试被认为是专门评估皮质前机制。结果表明，在11名有视觉先兆的偏头痛患者和13名无先兆的偏头痛患者中，大脑皮层前区对空间和时间视觉刺激的处理功能障碍;这两组无法区分。由于两组患者的皮质前功能障碍似乎都很常见，因此建议两组患者所经历的症状，如视力模糊和恐惧症，可能在皮质前水平有其基础。
This paper examines spatial and temporal processing in migraineurs (diagnosed according to International Headache Society criteria, 1988), using psychophysical tests that measure spatial and temporal responses. These tests are considered to specifically assess precortical mechanisms. Results suggest precortical dysfunction for processing of spatial and temporal visual stimuli in 11 migraineurs with visual aura and 13 migraineurs without aura; the two groups could not be distinguished. As precortical dysfunction seems to be common to both groups of patients, it is suggested that symptoms that are experienced by both groups, such as blurring of vision and photophobia, may have their basis at a precortical level.
