Quantifying Learning Beyond Exams…..

Terms used to quantify learning in animal models:
• Habituation- animal is less reactive to an external stimulus
• Sensitization- animal is more reactive to an external stimulus
• Conditioning (albeit it classical or operant)- behavioral or physiological events are reinforced by pairing two external stimuli that are inherently mutually exclusive (bell and food)

LTP vs LTD in the hippocampus
LTP: long-term potentiationLTD: long-term depression
![Page 11: Learning](https://reader036.fdocuments.in/reader036/viewer/2022070421/56816030550346895dcf49bb/html5/thumbnails/11.jpg)
LTP vs. LTD is dependent on the number of connections and successful transmissions

This results in a change in the intensity of neuronal firing, pre-synaptically

And in a change in receptor expression, post-synpatically
