Editing Systems neuroscience (section)

== Observations ==
Systems neuroscience is observed through [[electrophysiology]], which focuses on the electrical activity of biological systems in an organism. Through electrophysiology studies, the activity levels of different systems in the body help explain abnormalities of systematic functioning, such as an abnormal heartbeat rhythm or a stroke. While the main focus of electrophysiology is the heart, it does provide informational scanning of brain activity in relation to other bodily functions, which can be useful for the connection of neurological activity between systems.

Although systems neuroscience is generally observed in relation to a human’s level of functioning, many studies have been conducted on [[drosophila]], or the small fruit fly, as it is considered to be easier due to the simpler brain structure and more controllable genetic and environmental factors from an experimental standpoint. While there are strong dissimilarities between the functioning capabilities of a fruit fly in comparison to a human, these studies still provide valuable insight on how a human brain might work.

[[Neural circuit|Neural circuits]] and neuron firing is more easily observable in fruit flies through functional brain imaging, as neuronal pathways are simplified and, therefore, are easier to follow. These pathways may be simple, but by understanding the basis of neuron firing, this can lead to important studies on a human’s neuronal pathway and eventually to a one-to-one neuron correspondence when a system is functioning.<sup>7</sup>
