Recent findings, such as a study showing that place cells respond to non-spatial dimensions, such as sound frequency, disagree with the cognitive map theory. Instead, they support a new theory saying that the hippocampus has a more general function encoding continuous variables, and location just happens to be one of those variables.
The field study did not involve endangered or protected species. Study site the study was conducted in changting county, which covers an area of 3099 km 2 and is located in the western fujian province of southeastern china (25°18′40″n-26°02′05″n, 116°00′45″e-116°39′20″e).
Calculating the euclidean distance (shortest path) between two sequential serve locations to identify spatial variation within a player’s serve pattern. To identify where a player served at key points in the match we assigned an importance value to each point based on the work by morris.
