Neural Networks & Information Processing

55 Minutes

Objective

Students will map the "Input-Process-Output" model to biological neural circuits, distinguishing between rapid reflexes (spinal cord level) and complex decision-making (brain/interneuron level).

Key Misconception

Students often believe all "thinking" happens in the brain. Emphasize the role of the spinal cord in reflexes—the signal often loops back before it even reaches the brain to save time!

Quick Write: Fire vs. Lunch

Circulate while students write. Look for students who mention "speed" or "choice."
Transition: "One of these is an automatic circuit (reflex), the other requires a massive data search (memory) and evaluation (decision making)."

10 Min

Video & Pause Points

Use Slide 4 to play the video. Pause at the timestamps listed on Slides 5, 6, and 7.

Pause 0:43 (Functions) Ask: "If you're remembering your locker combo, which type of processing is that?" (Memory).

Pause 1:25 (Lego Path) Explain: The spinal cord handles the lift-off *before* the brain feels the pain.

Main Activity: Circuit Breakers

Assign groups and distribute 1 Scenario Card per group.

Scenario	Primary Circuit Type	Complexity Note
Cactus	Reflex	Low Complexity. Spinal cord loop.
Math Final	Memory / Decision	High Complexity. Deep brain retrieval.
Boss Battle	Perception / Choice	Medium-High. Requires rapid interneuron signal.
