Occur?... Most of the time.
Occur?... Once the dendrites of the new neuron have been
“activated” by neurotransmitters from the previous
neuron, a change in the electrical charge of the new
neuron begins in the axon hillock
neuron This charge is then sent down the axon of the cell in
order to tell the terminal branches of that cell to release
a neurotransmitter to the new adjacent cells
neurotransmitter In other words, if we find more synapses, more
neurotransmitters, and specifically, more excitatory
neurotransmitters, we’ll see a neuron that’s more active

How By understanding the construction of our
neurons, we can better appreciate the
construction of our nervous system and the
errors that can occur
errors Also, by understanding how our neurons work,
we can start to understand how we can
measure the activity and changes that occur in
