social transmission of food preference steps

• Step 1: Demonstrator rat is eating some food

• Step 2: Social interaction takes place without any food present
○ Observer (the test rat) interacts with the demonstrator and smells the other rats breath
○ Smells cumin

• Step 3: Delay

•Step 4: Observer is given a test and given the choice btw two options
○ Option 1: food that smells like the one the demonstrator ate
-Option 2: other food

2

T or F: Rats are very social and learn from each other from olfaction, and are afraid novel foods .Rats are very wary of things (especially new food)

True

3

what's the ida of the experiment

Idea is that if the rats remember the social interaction they will eat the food with the smell similar to that of the demonstrators

4

dotted line

what the rat would have eaten if they have never been exposed to the breath of a cumin eating rat

5

two types of receptors important for memory

AMPA and NMDA

6

AMPA

-not critical for learning , but it precedes NDMA

-Necessary for activation of NDMA

7

NMDA

-is critical for memory

-If AMPA is inhibited then it blocks NDMA from being activated

8

Tagging

Cell A and cell B, interact with one other early on

-Cell A: HPC
-Cell B: OFC

9

AP 5

a selective NMDA receptor antagonist that competitively inhibits the ligand binding site of NMDA receptors. AP5 blocks NMDA receptors in micromolar concentrations.
