PMID:25056804. |
using "bottom-up" ms for protein identification and validation of results by immunohistochemistry, we could identify two proteins, skeletal muscle alpha actin and carbonic anhydrase iii, which discriminate between the secondary damage on adjacent tissue and the primary traumatized muscle area. |

alpha increases during creative ideation could reflect more internally oriented attention that is characterized by the absence of external bottom-up stimulation and, thus, a form of top-down activity. |

the observed contralateral-central alpha suppression (conditions d vs. b and d vs. c) may reflect primarily a top-down cognitive process such as attention, while the widespread gamma enhancement (conditions d vs. a) may partly reflect tonic pain processing, representing the summary effects of bottom-up stimulus-related and top-down subject-driven cognitive processes. |

our results demonstrated that 1) in the 1-sec pre-stimulus interval, frontal alpha (8-12 hz) activity was higher on trials where the salient distractor captured attention and the first saccade (bottom-up win); and 2) there was a transient pre-saccadic increase in posterior-parietal alpha (7-8 hz) activity on trials where the first saccade went to the target (top-down win). |
