概括

面具的对比度和尺寸不会改变连续闪光抑制 (CFS) 中的抑制深度. 研究人员可以改变这些面具特征,而不会改变整眼抑制的强度.

科学领域:

神经科学是一个神经科学.
视觉感知视觉感知视觉感知
心理物理学的精神物理.

背景情况:

持续闪抑制 (CFS) 是一种视觉掩饰技术,用于研究眼内冲突和意识.
追踪连续闪光抑制 (tCFS) 允许测量抑制深度.
以前的研究已经探索了面具对比度和尺寸如何影响抑制时间,但不是抑制深度.

研究的目的:

通过使用tCFS来研究面膜对比对抑制深度的影响.
检查掩盖刺激大小对抑制深度的影响.
为了确定CFS面具特征是否会影响整眼抑制的基本强度.

主要方法:

实验1:在tCFS中操纵面具对比度,以测量其对抑制深度的影响.
实验2:在tCFS中改变掩盖刺激的大小,以评估其对抑制深度的影响.
测量了突破和重新压缩的值,以计算压缩深度.

主要成果:

增加面具对比度提高了目标意识的门,但没有改变抑制深度.
面具对比度的变化导致突破和重新抑制值的比例变化,保持恒定的抑制深度.
改变面具大小并没有影响突破/抑制值或抑制深度.

结论:

在CFS中抑制深度保持不变,无论面具的对比度或大小如何.
面具的对比度和尺寸可以在CFS实验中独立操纵,而不会影响抑制强度.
这些发现支持了整眼抑制在局部空间区域内运作的观点,与主要视觉皮层受体场相一致.

Difference from Background: Limit of Detection

Difference from Background: Limit of Detection

The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Super-resolution Fluorescence Microscopy

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...
