Question

Explain Kandel's experiments on habituation in aplysia, the neural circuit involved, and how this relates to both short-term and long-term learning.

·         Explain LeDoux's experments on fear (threat) learning, the neural circuit involved, and what this tells us about associative learning.

·         Explain Thompson's experiments on eye-blink conditioning, the neural circuit involved, and what this tells us about associative learning.

·         Explain Ito's experiments in the cerebellum, the specific neural circuit involved, and what this tells us about long-term depression.

Explanation / Answer

Answer:

1.Eric Mandel was awarded noble price(2000) for habituation and neural plasticity. In his experiment he demonstrated that reduced probability of response to small stimulation happened repeatedly.

2.In Me Douxcs experiment on fear (threat learning) Rat were conditioned for tone as a threat.

Result:

3.In Thompson's experiment when tone was played, air was blown to the rabbits eye thus cause little response but it increase over time.this experiment showed Involvement of neural circuit of interpostitus & cerebellum's red nucleus.

4.Ito's experiment describe that climbing parallel fibre's signal were received by purkinje cell.

Result:
