Distribution of neurons with phasic responses to different task-related events
| Region | Session | Task encoders |
Task non-encoders | |||
|---|---|---|---|---|---|---|
| Cue onset | Instrumental response | Food delivery | Food consumption | |||
| mPFC | Vehicle | 5.98 | 23.07 | 5.11 | 48.71 | 38.46 |
| Amphetamine day 1 | 6.73 | 26.92 | 8.65 | 44.22 | 41.34 | |
| Amphetamine day 3 | 7.69 | 37.49 | 10.57 | 35.57 | 34.61 | |

The proportion (percentage) of neurons with phasic responses to at least one of the following events is displayed for each region: cue onset, instrumental response, food delivery, and food consumption. Neurons without any phasic response were classified as task non-encoders. Note that some units showed phasic responses to more than one event, and, therefore, the proportion of task non-encoder neurons is higher than the sum of various task encoder neurons. Data are presented as proportion (percentage) of each type of response in each session.
