Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

neuron causes Neural signal.
Mechanism: A neuron fires an electrical impulse — the neural signal — along its axon to the next cell.

The earenablesNeural signalEstablished
The ear turns sound into neural signals.
Mechanism: Hair cells in the inner ear convert the vibrations of a sound wave into nerve impulses the brain can read — a sound wave re-encoded as information.

Hearing depends on neural signals reaching the brain.
Mechanism: Auditory perception depends on neural signals: the ear turns sound waves into nerve impulses the brain reads as hearing.

A neural signal is a biological signal.
Mechanism: A nerve impulse is a travelling electrical-chemical pulse that carries information — the body's own signalling system.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node lengthens the structural route between Artificial neural network and Network from 2 to 3 steps (they stay connected — alternative routes exist).
structural · Structural removal simulation — not a historical or causal counterfactual.
29% of its relationships cross field boundaries, reaching 14 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no key date stored · 7 of 7 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 2 foundations (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 2 foundation relations. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
1 concept build on this directly, 2 in total, across 7 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.

A neural signal is a tiny electrical pulse that travels along a nerve cell to carry information — for example, from your ear to your brain so you can hear a sound.

Information
Anything that reduces uncertainty. It can be encoded into a signal, sent across a channel, and decoded — and noise can corrupt it on the way.
Ask: what did the receiver not know before, and what does the message let them rule out?
Thresholds & tipping points
A level below which little happens and above which the behaviour changes sharply — sometimes irreversibly.
Some changes are gradual; others wait, then flip all at once.
- Connects 7 other ideas across 3 disciplines.
- A cross-disciplinary bridge — its connections reach into 14 other fields.
- Most of its connections are of the “Analogy & transfer” kind.
- It exercises 2 reusable thinking patterns.
Derived from the graph’s real structure — observations, not a score.
