a1 questions?
• I realize some of the wording is confusing…
Before we move on to new material
• How does the brain work?
Quiz
1. What is the significance of the amoeba analogy?
2. Why is there a 1ms delay between neural firings?
3. What is the significance of the frog’s inability to
compensate for the surgery?
4. Why is neural development crucial to our
understanding of the brain’s role in language
production? (i.e. What’s the point of yesterday’s
lecture?)

Key Points from last lecture
• Three stages of development
– Prenatal
– Postnatal fine-tuning
– Learning
• Humans come pre-wired for learning
– Some plasticity
• Activity dependent fine tuning
• Long term memory
• Pre-wiring biases the way we learn
