Discussion
The following table shows attributes of biological and artificial neurons respectively. Match the following according to the functions performed by their counterpart :
| List I | List II |
|---|---|
| (i) Cell/soma | (a) Neuron/Node |
| (ii) Synapse | (b) Weights |
| (iii) Dendrites | (c) Net input |
| (iv) Axon | (d) Output |
Answer: A
The correct matching is (i)-(a), (ii)-(b), (iii)-(c), (iv)-(d).
| Cell body (soma) | Neuron or node |
| Synapse | Weights |
| Dendrites | Net input |
| Axon | Output |
The soma, where signals are combined, corresponds to the artificial neuron or node itself. The strength of a synapse, which scales the signal passing from one neuron to another, corresponds to a connection weight. The dendrites carry incoming signals to the cell, the counterpart of the inputs summed into the net input. The axon carries the neuron's signal onward, as the node's output does.
Each of the other options rotates the pairs, for example matching the axon to the weights.
