Brain

Synaptic Pruning and Rewiring →

Your brain prunes unused connections and builds new ones in response to activity—the balance between loss and growth determines whether capacity expands or shrinks over time.

Developmental Reinterpretation →

The same behavior gets reinterpreted as you develop the cognitive tools to see what the behavior expresses—what looks like interference at one stage looks like principle at another.

Encoding Richness and Retrieval →

Your brain stores information by linking it to the sensory and motor activity that happened during learning—more channels firing during encoding means more pathways to retrieve the memory later.

Sensory Fusion and Confidence →

Your brain combines signals from multiple senses to decide how confident it is about which way is up—when one sensor gets noisy, the brain trusts it less and behavior slows to protect against the uncertainty.

Wiring Follows Demand →

Neural systems allocate connection density based on behavioral demands—circuits used for high-precision tasks get more wiring, while general-purpose circuits stay sparse.

Structural Accumulation and Detection →

Physical structures change continuously through repeated activity, but become measurable only when enough material has accumulated—different processes build at different rates, reaching detectability at different times.

Temporal Binding Windows →

Events that happen close enough in time can link into a single pattern if the window capturing them is wide enough—no repetition required.

Sorting Into Subtypes →

Subdividing a category makes each subgroup more internally similar (improving prediction within the subgroup) but fragments the population into smaller samples (reducing statistical power)—the trade-off is precision against proof.

Slope Detection Between Samples →

Pattern recognition by comparing readings across positions — detecting 'more here than there' reveals direction without mapping the whole field.
