I would do one in paper mache'. Take a balloon and then tear strips of paper, get craft glue or wheat paste and put your paper in it . Make sure your strips of paper are well coated with the glue/paste. Now put the strips of paper over your balloon because you are going to make a head. You want this fairly thick on the balloon. Don't want to see any blank spots on the balloon. Let it dry. When it is fully dry pop the balloon and now you will have a paper mache head. Get tempera paint and paint it one color. Then draw your brain on it and label using different colors for each section. Now, you can go through the bottom of your head and put in LED lights in the areas you want to light. This should work. I stess that the paper strips must be thick on your balloon.
Neurons are specialized cells that make up the nervous system. They are responsible for transmitting electrical and chemical signals throughout the body, allowing for communication between different parts of the body and the brain. Neurons have structures called dendrites to receive signals, a cell body that processes information, and an axon to transmit signals to other neurons or cells.

The tip of a neuron's axon culminates in several endings call terminal buttons. When an action potential is conducted down the axon, this is where it goes.
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.
Neurotransmitters released from one neuron can either excite or inhibit the next neuron. Excitatory neurotransmitters make the receiving neuron more likely to fire an action potential, while inhibitory neurotransmitters make it less likely. This process allows for communication and coordination between neurons in the nervous system.

Sensory neurons have their cell bodies in the dorsal ganglion at the one or two segemental levels from the dendrite entry. They make a synapse onto interneurons in spinal cord. Motor neurons have their cell bodies in the spinal cord.

I am not certain, but the longest cell of which I am aware is a subset of spinal motor neurons. Motor neurons extend out from the spinal cord and synapse onto muscles to control their contraction. The longest motor neurons and my vote for longest cell in the body are the motor neurons that extend out from the lumbar spine to make connections with the muscles of the toes.

For a cell model project, you could use various materials such as clay, styrofoam, or even edible items like gelatin or candy to represent the different organelles of a cell. Make sure to include a cell membrane, nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and other key structures. Providing labels and a brief explanation of the function of each organelle will enhance your model.
