Editing Systems neuroscience (section)

== Major branches ==
Systems neuroscience has three major branches in relation to measuring the brain: behavioral neuroscience, computational modeling, and brain activity. Through these three branches, it breaks down the core concepts of systems neuroscience and provides valuable information about how the functional systems of an organism interact independently and intertwined with one another.

=== Behavioral neuroscience ===
[[Behavioral neuroscience]] in relation to systems neuroscience focuses on representational dissimilarity matrices (RDMs), which categorizes brain activity patterns and compares them across different conditions, such as the dissimilar level of brain activity observing an animal in comparison to an inanimate object. These models give a quantitative representation of behavior while providing comparable models of the patterns observed.<sup>5</sup> Correlations or anticorrelations between brain-activity patterns are used during experimental conditions to distinguish the processing of each brain region when stimuli is presented.

=== Computational modeling ===
[[Computational model|Computational models]] provide a base form of brain-activity level, which is typically represented by the firing of a single neuron. This is essential for understanding systems neuroscience as it shows the physical changes that occur during functional changes in an organism. While these models are important for understanding brain-activity, one-to-one correspondence of [[Neural coding|neuron firing]] has not been completely uncovered yet. Different measurements of the same activity lead to different patterns, when in theory, the patterns should be the same, or at least similar to one another. However, studies show fundamental differences when it comes to measuring the brain, and science strives to investigate this dissimilarity. 

=== Brain activity ===
[[Electroencephalography|Brain activity]] and brain imaging help scientists understand the differences between functional systems of an organism in combination with computational models and the understanding of behavioral neuroscience. The three major branches of systems neuroscience work together to provide the most accurate information about brain activity as [[neuroimaging]] allows in its current state. While there can always be improvements to brain-activity measurements, typical imaging studies through electrophysiology can already provide massive amounts of information about the systems of an organism and how they may work intertwined with one another. For example, using the core branches of systems neuroscience, scientists have been able to dissect a migraine’s attack on the nervous system by observing brain-activity dissimilarities and using computational modeling to compare the differences of a functioning brain and a brain affected by a migraine.<sup>6</sup>
