Extended Data Fig. 2: List of all objects used to identify object-vector cells.

a, All objects used in experiments with object-vector cells. Objects had either a prism-like or cylinder-like appearance, with some modifications, and varied in height and width. b, Shape, dimensions, colour and material of each object, numbered as in a. c, Prismatic objects of increasing length used for experiment in which a point-like prism tower was changed across trials into a lengthy wall. Objects consisted of 21-cm-high, 3-cm-wide towers of Duplo Lego bricks with lengths of 6.75 cm, 25 cm, 37.5 cm and 62.5 cm. d, Cardboard cylinders of increasing diameter (2 cm, 5 cm, 10 cm, 15 cm and 20 cm). e, Prismatic Duplo Lego objects of increasing height (2 cm, 10 cm, 20 cm and 40 cm).
