Either crocins, at a dose which did not influence animals' motor activity (50 mg/kg), or diazepam (1.5 mg/kg), significantly increased the latency to enter the dark compartment and prolonged the time spent in the lit chamber in the rats.
An alternate scene shows two people fencing inside a white lit chamber, one in black cloths and one in white.
Furthermore the time to approach the end of the lit chamber was significantly altered in sham-treated runners (F1,44 = 11.43; p = 0.002; Fig. 5).
The reduced ability of dunce mutants to suppress prepotent reflexes is also evident in another visual paradigm, aversive phototaxic suppression, where wild-type flies learn to avoid a lit chamber associated with quinine whereas dunce fail to suppress their phototaxic reflex over time [7].
The amount of time it took for the mouse to cross from the lit chamber to the unlit chamber was recorded, with a maximum time of 300 s.
On day 3, mice were placed in the lit chamber, and the door to the unlit chamber opened after 30 s.
Mice were trained and tested in a two-chamber passive avoidance cage, in which one chamber was permanently darkened and separated from the lit chamber by a sliding door.
On day 1, mice were placed in a lit chamber in the GEMINI testing device (San Diego Instruments; San Diego, CA, USA), and 30 s later a door opened to an unlit but otherwise identical chamber.
Rather than staging a conventional catwalk show, Pugh's spring/summer 2015 collection was modelled by performers in the dimly-lit chambers of New York City's Pier 36.
The ground floor contained two guardrooms, each 21 feet wide, and latrines, with spiral staircases in the corner of the gatehouse running up to the first floor, where relatively well-lit chambers with fireplaces probably accommodated the garrison's officers.
A steel-gray door slides open, revealing a blue-lit chamber the size of a long, narrow elevator.
