In addition to the variety of settings, various pharmacological and behavioral approaches are available for your Nembutal addiction treatment. Stereotaxic coordinates for these lesions are shown in Table 1. nembutal pills were produced by injecting two 0.15 μl injections of 100 mm NMDA (Sigma, St. Louis, MO) into each hemisphere. 5) 0.1-0.15 μl injections of ibotenic acid (10 mg/ml; Bioresearch Technologies, San Rafael, CA) into each hemisphere. It also avoided repeated saline injections. In these latter instances, the experimental sessions (e.g., cue-rotation or cue-removal) were always bracketed with two standard sessions. For these cells, the first standard session (pre-rotation) was used for measuring place cell properties and also served as the control session for the cue-rotation experiment. The cue-rotation experiment consisted of three separate sessions (Fig. 1 B).

The counter-rotation session that followed the cue-rotation session usually served as the control session for the cue-removal experiment. Cue-removal experiments usually followed cue-rotation experiments immediately if cell isolation remained intact and a clearly defined place field was present in the previous session. Diagram of cue card position and order of sessions during the standard session (A), cue-rotation experiment (B), and cue-removal experiment (C). When possible, individual cells were tested sequentially on the same day in all three experiments in the order listed above. Other pixels were displayed as orange, red, green, blue, or purple, based on the firing rate in ascending order. Yellow pixels represent firing rates of zero. Data analysis. The firing rate of the recorded cell and the position of the animal as indicated by the red and green LEDs were recorded on a personal computer at a rate of 60 Hz using a National Instruments (Austin, TX) DIO-96 data acquisition board. If a cell displaying location-specific firing was isolated, the animal was removed from the cylinder and the apparatus was prepared for recording. All use of rats complied with the National Institutes of Health guidelines on the care and use of laboratory animals and was approved by the local Institutional Animal Care and Use Committee.

There were no rats. For some cells, there was more than one contiguous area that qualified as a place field. Experimental manipulations. Place cell activity was monitored in the recording cylinder over one or more 16 min sessions, during which the rat chased food pellets dropped randomly from above. In the first session (pre-rotation), cell activity was monitored with the cue centered at the standard position. In the standard session, cellular activity was monitored while the animal foraged in the recording cylinder with the white cue card centered on the east wall, the center of which is defined as the 0° position. Screening for place cells involved examining the electrical signal on each of the 10 implanted wires while the animal foraged in the recording cylinder. If no location-specific activity was detected, the cannula containing the wires was advanced 25-50 μm, the animal was returned to its home cage, and no additional screening for cellular activity occurred for at least 6 hr. The wires were threaded through a stainless steel cannula that was moveable in the dorsoventral direction after being fixed to the skull using dental acrylic. The head direction of the animal was determined by the relative position of the red and green LEDs.

Occasionally, after repeated sessions, the animal became unmotivated to retrieve food pellets and did not move around the apparatus sufficiently during recording. This session was followed by a cue-return session in which the cue card was replaced in the standard position without changing the floor paper or removing the animal from the apparatus. In the cue-removal session, recordings were made after the floor paper was changed, the cue card was removed, and the rat was returned to the cylinder without disorientation treatment. In the third session, the cue was returned to the original 0° position (counter-rotation). Whereas all cells were recorded in this first session, some cells were also recorded during one or two additional experiments in which the cue card was manipulated. The usual laws o f supply and demand that govern the illegal drug trade do not apply, as no one will ever want more than one bottle o f this drug.
