1. Simple forms of learning
Eric Kandels research on habituation and
sensitization in aplysia has led to great
advances in understanding the neural circuitry
underlying these simple forms of learning.

One-Minute Paper (Part 1)

• Think of something you really like and write it
  down.
• Now think of something that very specifically
  makes you think of or is necessary for what you
  wrote in 1. and write it down.

One-Minute Paper (Part 2)

• Think of something you really like and write it
  down.
• Now think of something that very specifically
  makes you think of or is necessary for what you
  wrote in 1. and write it down.
• If I were to show you what you wrote in 2. how
  would it make you feel? Is that how the something
  in 1. makes you feel?
• In your example, identify the UCS, UCR, CS, CR.
