The electroencephalogram (EEG) was measured in an endogenous orienting paradigm
where symbolic cues indicated the likely side of to-be-discriminated targets.
Combined results of event-related lateralizations (ERLs) and a newly derived
measure from wavelet analyses that we applied on the raw EEG and individual
event-related potentials (ERPs), the lateralized power spectra (LPS) and the
LPS-ERP, respectively, confirmed the common view that endogenous orienting
operates by anterior processes, probably originating from the frontal eye
fields, modulating processing in parietal and occipital areas. The LPS data
indicated that modulation takes place by increased inhibition of the irrelevant
visual field and/or disinhibition of the relevant to-be-attended visual field.
Combined use of ERLs, the LPS, and the LPS-ERP indicated that most of the
involved processes can be characterized as externally evoked, either or not with
clear individual differences as some evoked effects were only visible in the
LPS-ERERP, whereas few processes seemed to have an internally induced nature.
Use of the LPS and the LPS-ERP may be advantageous as it enables to determine
the involvement of internally generated lateralized processes that are not
strictly bound to an event like stimulus onset. 相似文献

The revolution in science inaugurated by quantum physics has made us aware of the role of observation in the construction of data. Eugene Wigner remarked that in quantum physics we no longer have observables (invariants), only observations. Tongue in cheek, I asked him whether that meant that quantum physics is really psychology, expecting a gruff reply to my sassiness. Instead, Wigner beamed understanding and replied "Yes, yes, that's exactly correct." David Bohm pointed out that were we to look at the cosmos without the lenses of our telescopes we would see a hologram. I extend Bohm's insight to the lens in the optics of the eye. The receptor processes of the ear and skin work in a similar fashion. Without these lenses and lenslike operations all of our perceptions would be entangled as in a hologram. Furthermore, the retina absorbs quanta of radiation so that quantum physics uses the very perceptions that become formed by it. In turn, higher-order brain systems send signals to the sensory receptors so that what we perceive is often as much a result of earlier rather than just immediate experience. This influence from inside out becomes especially relevant to our interpretation of how we experience the contents and bounds of cosmology that come to us by way of radiation. 相似文献
