An alternative hypothesis was that the mice were moving the discs in directions determined by another factor – perhaps perceiving them as super-normal bedding stimuli and carrying them back to the nest-box, or perhaps using them as spatial reference points with respect to the location of a visual reference point.
An example of different attribute types is the color of a disc and the direction of a grating pattern in that disc.
"The Thing That Never Was", a track on the bonus disc, shows the direction Matheos and Portnoy originally planned to take the album in.
Specifically, we tested whether physically plausible auditory signals (Experiment 1), and two additional types of extrinsic visual signals (location of a luminous disc and rotation direction of a random-dot field, Experiments 2A and 2B), could be learned and used to disambiguate the rotation direction of an ambiguous cube.
Make sure that you insert the disc the correct direction, with the label facing up.
32 images from each retina were selected at 2 mm away from their optic disc in four directions (dorsal-nasal-ventral-temporal) by stereological acquisition system.
Moreover, we selected 32 images from each retina in three experimental groups (PT, CO, SM-sham control) at 2 mm away from their optic disc in four directions (dorsal-nasal-ventral-temporal) by stereological acquisition system in order to quantify the morphological variety.
Rather, the locations to which the wood mice carried the discs, and the direction they took while moving them, depended solely on the current focus of their activity.
A slug was added to the centre of each Petri dish perpendicular to the axis between the leaf discs, with the direction alternated as dishes were prepared.
The most commonly used pressure relief valve type is the direct-loaded pressure relief valve in which the fluid pressure acting on the valve disc in the opening direction is opposed by a direct mechanical-loading device such as a weight or spring.
