Abstract

A number of authors have proposed that changes in temporal frequency within the range of 0-30Hz may be used to differentiate contributions from the magno- and parvocellular systems. The present analyses estimate the percentage of active magnocellular cells as a function of frequency based on published cut-off values for magno- and parvocellular cells. These analyses indicate that varying the temporal frequency over the range of 0-30Hz has little effect upon the percentage of active magnocellular cells. The analyses were also carried out for a series of hypothetical cut-off frequencies and standard deviations of these frequencies for magnocellular cells. The results of these simulations indicate that even large alterations in these values do not alter the above conclusion to a noteworthy extent.

摘要

许多作者提出，在 0-30Hz 范围内的时间频率变化可用于区分大细胞和小细胞系统的贡献。本分析根据大细胞和小细胞的已发表截止值，估计了作为频率函数的活动大细胞的百分比。这些分析表明，在 0-30Hz 的范围内改变时间频率对活动大细胞的百分比影响很小。还对一系列假设的截止频率和大细胞频率的标准偏差进行了分析。这些模拟的结果表明，即使这些值发生很大的变化，也不会在很大程度上改变上述结论。
