  3. Where we stand • Last Week • Intro and Brain basics • This Week • Neural Development • Psycholinguistics • Coming up • Neural Nets and Backprop

  4. a1 questions? • I realize some of the wording is confusing…

  5. Before we move on to new material • How does the brain work?

  6. Quiz • What is the significance of the amoeba analogy? • Why is there a 1ms delay between neural firings? • What is the significance of the frog’s inability to compensate for the surgery? • 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?)

  7. 5 levels of Neural Theory of Language Spatial Relation Motor Control Metaphor Grammar Cognition and Language Computation Structured Connectionism abstraction Neural Net SHRUTI Computational Neurobiology Triangle Nodes Biology Neural Development Quiz Midterm Finals

  8. 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
