The human brain contains roughly 86 billion neurons connected by about 100 trillion synapses — connections between neurons. Information travels as electrical impulses along neurons and chemical signals across synapses.
Different regions specialise in different functions. The prefrontal cortex handles planning, decision-making, and personality. The hippocampus forms and retrieves memories. The amygdala processes emotions, particularly fear. The cerebellum coordinates movement and balance. The brainstem controls basic survival functions like breathing and heart rate.
Memory isn't stored in one location but distributed across networks. Long-term memories form through synaptic strengthening — when neurons repeatedly fire together, their connections strengthen, which is why practice and repetition improve memory. Sleep is critical for consolidating memories from short-term to long-term storage.
The brain is remarkably plastic, especially in youth. It reorganises in response to experience and learning. Neuroplasticity continues in adulthood, though more slowly. This is why learning new skills at any age remains beneficial and why stroke rehabilitation can be effective.

Here is the most practical way I know to approach photosynthesis:
**Step 1 — Understand what you actually need from photosynthesis.** Most people skip this and spend time solving the wrong problem. Write down your specific goal in one sentence.
**Step 2 — Survey the landscape.** Look at 5 real examples of it being handled well. You will notice patterns across them that tell you which approach fits your situation.
**Step 3 — Start with the minimum working version.** Do not build the complete solution first. Validate that the core idea works in your context.
**Step 4 — Test under real conditions.** Real usage always surfaces something the examples didn't cover.
**Step 5 — Iterate.** The first version is rarely the right version — plan for 3 refinement cycles.
Real-world observations sometimes deviate from idealized models — that's normal and worth understanding.
The part most people underestimate with photosynthesis: the edge cases accumulate quickly once you're past the basic examples.
