<p>Is there a difference?</p>
<p>Edit: also, what is the difference between systems neuroscience and cognitive neuroscience</p>
<p>Psychology is a much broader field. Cognitive neuroscience is a subfield of psychology that has to do with the neurological correlates of higher=level mental functions, such as memory, language, etc. Psychology includes many other subfields including social psychology, developmental psychology, etc. Systems neuroscience has to do with neural circuits and systems and how these are organized into neural networks. Its level of analysis can range from the cellular and molecular level to whole nervous systems.</p>
