Biological and artificial neuron comparison A labeled biological neuron maps dendrites to inputs, synapses to weights, soma to weighted summation, firing threshold to activation, and axon to output. Dendrites Soma Axon x₁ × w₁ x₂ × w₂ x₃ × w₃ Σ + bias Activation → output Useful analogy: receiving signals → integrating influence → producing an output. Important limit: biological neurons have complex chemistry, timing, plasticity, morphology, and network context.

Core Formula

z = Σ(xᵢwᵢ) + b

The activation function transforms z into the neuron output: y = f(z).

Frequently Asked Questions

Are artificial neurons biologically accurate?

They are simplified mathematical abstractions. They omit most biological chemistry, timing, structure, and adaptive behavior.

How many questions are included?

The complete bank contains 129 questions across anatomy, signaling, calculations, learning, applications, ethics, and troubleshooting.

Can I take only calculation questions?

Yes. Choose Calculation only from the quiz mode menu.

How does negative marking work?

Each incorrect response subtracts 0.25 points. A correct response using a hint earns 0.75 points.

What does adaptive difficulty do?

It starts with mixed questions and reorders remaining items based on recent accuracy.

Are results saved online?

No account is required. Progress and history are stored locally in the current browser.

Can I save the report as PDF?

Use Print or Save PDF. Your browser can create a printable PDF report.

Why are some questions labeled advanced?

Advanced questions address temporal dynamics, calibration, data leakage, fairness, and biological limitations.

What is a neuron bias?

Bias is a trainable offset. It shifts the activation threshold or decision boundary.

Can I review only incorrect answers?

Yes. Use the filter above the final question review.
