Motivation, as measured by the number of self-initiated trials in the 2AFC task decreased over time after saline but neural representation of action plans did not.
Top: The number of self-initiated trials binned in 5-minute increments and plotted across the 40-minute session. Males (open circle) and females (closed circle) start with high rates of trial …
