Dungeon stimulus (Bressan, 2001) with diamond target.
dungeon(visual_size=None, ppd=None, shape=None, cell_size=None, n_cells=None, target_radius=1, intensity_background=0.0, intensity_grid=1.0, intensity_target=0.5)[source]#

Dungeon stimulus (Bressan, 2001) with diamond target.

Parameters:

  • visual_size (Sequence[Number, Number], Number, or None (default)) – visual size [height, width] of grating, in degrees

  • ppd (Sequence[Number, Number], Number, or None (default)) – pixels per degree [vertical, horizontal]

  • shape (Sequence[Number, Number], Number, or None (default)) – shape [height, width] of grating, in pixels

  • cell_size (Sequence[Number, Number], Number, or None (default)) – size of individual cell (height, width)

  • n_cells (Sequence[Number, Number], Number, or None (default)) – the number of square cells (not counting background) per dimension

  • target_radius (int) – the “Manhattan radius” of the diamond target in # cells

  • intensity_background (float) – intensity value for background

  • intensity_grid (float) – intensity value for grid cells

  • intensity_target (float) – intensity value for target

Returns:

dict with the stimulus (key: “img”), mask with integer index for each target (key: “target_mask”), and additional keys containing stimulus parameters

Return type:

dict[str, Any]
