Ipsiversive rotation number was counted over 10 min after intraperitoneal injection of amphetamine (1 mg/kg) on days 4, 7 and 14 following intrastriatal injection.
Both the local rotation invariant versions (by counting occurrences of rotation groups), and the global rotation invariant versions (by computing Fourier descriptors of the groups) of the LBP-based texture descriptors are less rotation variant than the classic LBP descriptor but they still suffer from rotation variance.
It is expected that being an arithmetic task, multiplication involves more complexity in comparison with other four mental tasks, namely geometrical figure rotation, letter composing, counting and baseline-resting.
If a mouse was passively rotating on the rod (i.e. clinging) the number of passive rotations were counted.
Post-injection rotations were counted over 30 min, and visual behavioral assessments were made using video-recorded observations.
Wheel speed was controlled by a motor regulated with a DC power supply (MP3090; Powertech, Osborne Park, WA, Australia) and rotations were counted with a cyclometer calibrated to the circumference of the running wheel.
The number of rotations was counted visually for each rat.
Briefly, 1 min after pergolide injection, full rotations were counted in a cylindrical container (a diameter of 33 cm and a height of 35 cm) at 10 min intervals for 60 min in a quiet isolated room.
The tail hanging test was used to evaluate vestibular functioning; the rat was lifted by the tail and kept hanging at a height of 30 cm for a 15 s interval, and the number of head rotations was counted.
It was an unmanned biplane with player-piano bellows to power its gyroscope and a cash-register mechanism that calculated distance flown by counting the rotations of a propeller-like rotor.
