Abstract(E)	This study focused on the driver's brain activity in the prediction phase, which is the stage before recognition, and analyzed the effects of superior or inferior brain activity on recognition and driving performance on curved roads through a driving simulator experiment. A circuit course was set up, and changes in cerebral blood flow and gaze distribution were analyzed across 10 corners, together with the average of lane deviation in the first third of each curve. The results showed that activation of the frontal lobe during the prediction phase led to faster curve recognition and reduced lane departure in the curve sections. Overall, it was found that activation of the frontal lobe in the prediction phase improves both curve recognition and driving performance on curved roads.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.
