For each participant, we computed a normalized top-down index (TDI) that quantifies the degree to which the identified brain areas (see Figure 3) causally change the phase of left and right auditory cortex differentially for story and back condition.
Top, down, starting with hair.
This finding is consistent with lateralized alpha power reflecting an index of top-down control over spatial attention (Klimesch, 2012; Sauseng et al., 2005; Thut et al., 2006), and should here be interpreted as reactive, because the top-down signal was observed after conflict was encountered.
Table 1 discussed the design choice of proposed solution: Table 1 Design choice of solution Approach Pros and cons Top-down Using traditional search engine index as semantic layer ●→Pros: No need for content providers and developers to generate semantic information.
These experiments have revealed dissociable influences on participants' task choices thought to index their top-down intentions and their performance of the chosen task which is subject to the influences of between-task competition.
Foreign markets were also a sea of red, with Europe's top stock index down nearly 4percentt and Japan's Nikkei index down nearly 2percentt.
Rather than measuring individual achievements, the index takes a top-down approach, says Claude Cappon, president of the Canadian Council for Learning and project leader.
There's a separate top-down street-map with its own index, which is ideal for looking up roads mentioned in a particular book, and n mock-tourist style, there are also "walking tours" taking you on themed jaunts around the living map, narrated by actress and comedian Helen Atkinson-Wood.
Note that the TOI and STC index maps are top-down views.
The indices used are: (1) functional indices based on steady-state and dynamic trophic models; (2) structural indices based on bottom-up and top-down control mechanisms; and (3) qualitative keystone species indices using loop models (mixed control).
The present study examined the earliest index for the interplay between expectancy-based top-down and stimulus-driven bottom-up processes in sentence reading.
