Acronyms are good, mnemonics even better, but they’re just tools - the difference-maker is the architecture of your notes. In my experience, the minimum information principle doesn’t really apply to processes.
Say you want to learn the different G-protein coupled receptor signal transduction pathways:
If you made a card for every step of each pathway, you’d end up with > 20 cards. And you’ll still struggle to remember them.
If however you grouped them in some way that makes sense, you got two big advantages:
- While figuring out how to group the steps, you’re already studying the process.
- Grouped items are easier to remember (up to a certain threshold, for me it’s around 4) and you can form mnemonics for them.
The first card could ask which types of G-coupled receptors there are, and then you could create one card for each pathway → 5 cards. Since Gi and Gs affect the same pathway downstream, you could reduce it to 4 cards.
“But if the threshold for grouped items is around 4, what about the yellow highlighted proteins affected by cAMP?” - That’s where acronyms/mnemonics come into play. They’re ways to abstract away the complexity. Sure, you’ll need to go through the letters (or funky characters, whatever your mnemonic is) to fetch the facts, but it is much more efficient than forcefully carving standalone facts into your brain.
Same principle applies to data structures in computer science. The ones allowing for the fastest data retrieval usually take up more memory (=resource intensive, in our case literally requiring new synaptic connections to form), while the memory efficient ones require more elaborate information retrieval (in our case, taking a little detour using things we’ve already formed strong connections for). It’s always a tradeoff.
(Also please don’t study individual steps in signal cascades - I just used it as an example. Most pharmacology profs don’t ask for each step in such pathways, they just want to hear some key proteins involved in the process, e.g. the limiting factors or attackpoints for drugs, and those are usually somewhere way upstream.)
