Materials: thick white paper, colored pencil, thinner blue thread, thicker red thread (PS: copper wire in insulating skin needs to be divided), scissors and adhesive tape.

Neuron model

Production steps:

1. Draw the cell body of neurons on thick white paper with colored pencils, with a diameter of about 15-20cm, and then cut off the drawn cell body with scissors.

2. Connect several blue wires with the length of 10 cm to the edge of the cell body, and remove the insulation of the outer end of each wire with the length of 1 cm to expose a thin copper wire.

3. Connect the 1 red wire to the edge of the battery about 50 cm, and remove 1 cm from the insulation layer at the other end of the wire to expose a thin copper wire.

4. The production is completed.

Knowledge expansion:

The basic unit of neural network is neuron, and the mathematical model of neuron corresponds to biological neuron. In other words, the artificial neural network theory uses the abstract mathematical model of neurons to describe biological cells in the objective world.

Obviously, biological nerve cells are the material basis and source of the birth and formation of neural network theory. In this way, the mathematical description of neurons must be based on the objective behavior characteristics of biological nerve cells. Therefore, it is very important and necessary to understand the behavioral characteristics of biological nerve cells.

The topological structure of neural network is also based on the interconnection of nerve cells in biological anatomy. It is also very important to reveal the interaction between nerve cells. Neuron are that basic elements of neural network. Only by understanding neurons can we understand the nature of neural networks.
