In the Cover condition, a metallic plate prevented access to the drinking receptacle, as in the previous experiments.
By contrast, in the Cover condition, a metal plate blocked access to the receptacle during extinction, thereby preventing the rats from checking whether sucrose was present or absent behind the plate (Fig. 1, right panel).
On the other hand, if rats understand that the metal plate blocks access to information about the sucrose, they should understand that in Phase 2, the contingency between the light and sucrose might still be intact despite the fact that the metal plates make it impossible to monitor this contingency.
Plated gains access to roughly 2,300 physical stores and over 35 million customers per week.
A US embassy car which had arrived to pick her up around the same time as the shooting began had led to reports that the jihadists had used a vehicle with a diplomatic number plate to gain access to the hotel.
The absorbance was measured at 600 nm using microtiter plate reader to access the cell growth.
After the procedure, the animals were kept on a 37°C warm plate with free access to unlimited food and water.
The rats were placed on the top of a controlled preheated (52.5 ± 0.5°C for hyperalgesia; 45 ± 0.5°C for allodynia) and maintained hot plate surface, allowing access to the left hind paw withdrawal response to degree of the nociceptive threshold.
The crucial difference between the conditions was the placement of the cover: Whereas in the Cover condition, the metallic plate again blocked access to the drinking receptacle, in the No Cover condition, it was placed slightly to the left of the receptacle.
Access for plate insertion is through the same anterolateral approach and a distal incision may be needed for lower screw insertion.
