Nottebohm believed it was because fresh neurons helped store new song patterns within the neural circuits of the forebrain, the area of the brain that controls complex behaviors. -Motor Neuron How do proteins and other chemicals synthesized in the soma get to the synaptic knobs? In a diverging circuit, one neuron synapses with a number of postsynaptic cells. Neurons compute using rapid electrical impulses, which underlie our thoughts, behavior, and perception of the world. Traditional methods for measuring this electrical activity require inserting an electrode into the brain, a process that is labor-intensive and usually allows researchers to record from only one neuron at a time. Scientists hope that by understanding more about the life and death of neurons they can develop new treatments, and possibly even cures, for brain diseases and disorders that affect the lives of millions of Americans. Although this may not be exactly how these cells behave when they are in the brain, it gives us information about how they could be behaving when they are in the brains environment.
