Once the Neuron has been selected by Nina, the children (called the 'experimenters') then visit Nina, using fun experiments and games. Afterwards, Nina takes the children out to find out more about the answer to the question, sometimes with the help of their friends and family.
Here is what happens: The small groups of neurotransmitters are released into the synaptic cleft when they receive an order from Ca 2+ ions to do so. When the electrical signal reaches the presynaptic terminal, it opens some channels in the membrane (these are called voltage gated Ca 2+ channels).
A synapse is a gap that is present between two neurones. Action potentials are propagated across the synapse by synaptic transmission, also known as neurotransmission. The neurone that sends the signal is the presynaptic neurone, whilst the postsynaptic neurone receives the signal.
Nina then chooses one (or more) of the five Neurons inside her brain based upon which of the senses is most appropriate to answer the question. Once the Neuron has been selected by Nina, the children (called the 'experimenters') then visit Nina, using fun experiments and games.

A synapse is the site of communication between a neuron and another cell. There are two types of synapses: chemical synapses and electrical synapses. In a chemical synapse, a chemical signal— a neurotransmitter—is released from the neuron and it binds to a receptor on the other cell.

Key facts: action potential and synapses. Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.
