See Figure 3 for the Timeline of daily experimental procedure.imgsrc:https://en-cdn.bio-protocol.org/attached/image/20190329/20190329235855_7400.pngFigure 3. #####%%%%% output "Figure 3" are used in line10

Deprive animals of food to 82%-85% of their ad lib weights throughout the experiment. #####%%%%% output "the experiment" are used in line26
{"action": "protect", "output": "the experiment", "reagent": ["food"]}
Once animals reach the required weight, .

feed daily with 9 g (±1.5 g) of rat chow to maintain body weight #####%%%%% output "body weight" are used in line20
{"action": "send", "output": "body weight", "reagent": ["rat chow"]}
All manipulations must be carried out at the same time every day . #####%%%%% output "sucrose solution" are used in line14
{"action": "carry", "output": "sucrose solution", "reagent": ["Figure 3"]}
Efforts must be made to minimize suffering .

Moreover, sucrose solution must be prepared fresh daily to avoid contamination.
{"action": "prepare", "output": "", "reagent": ["sucrose solution"]}
cSNC training lasts 19 daily sessions: 16 preshift sessions followed by 3 postshift sessions.
{"action": "shorten", "output": "", "time": ["19 daily sessions"]}
In the cSNC task, at least two experimental groups are required.

During the preshift sessions, one of them has access to a large reward (e.g., 32% sucrose solution) ).
{"action": "have", "output": "", "reagent": ["body weight"]}
During postshift sessions, both groups are exposed to the small reward (4% sucrose solution).Before each session, animal racks must be moved into a different room where the experiment will be held, allowing the rats 15 min in their home cages to settle down, before placing them the consumption chambers.
{"action": "move", "output": "", "time": ["postshift sessions"]}
The contrast session lasts 5 min from the first contact with the sipper tube.
{"action": "shorten", "output": "", "time": ["5 min"]}
The position of the bottle is counterbalanced daily to minimize the effects of side preference.
{"action": "reflect", "output": "", "reagent": ["the experiment"], "container": ["the bottle"]}
The animal is placed back in its home cage at the end of the session.
{"action": "put", "output": "", "container": ["its home cage"], "reagent": ["the animal"]}
Session duration for each box can be measured manually with digital clocks (Digital Onstart 100). #####%%%%% output "training" are used in line38
{"action": "evaluate", "output": "training", "container": ["each box"], "reagent": [""], "device": ["digital clocks (Digital Onstart 100)"]}
then transforming the weight to milliliters ()

having accounted for the density of each solution

using the formula

All animals receive training every day in groups of 4, with the order of groups counterbalanced across days.
{"action": "provide", "output": "", "reagent": ["training"]}
At the end of every session, contrast chambers must be wiped with a wet paper towel removed as needed.
{"action": "pull", "output": "", "reagent": ["wet paper towel"], "container": ["contrast chambers"]}
