…the spinal cord and the nerve pathways that radiate out from it to much of the body; and the basal nerve system (thought to be a second brain in your gut) to name only a few components of this complex communications network of the body. When studying neuroscience, one must be able to understand the other systems in the body (i.e. cardiovascular and endocrine systems) because the nervous system works in conjunction with these other systems.

To study the discipline of neuroscience, a student will take complex science courses such as neurobiology and cognitive neuroscience. Neurobiology is the study of the cells and organelles of the body and how they function as a whole to contribute to various behaviors and processes of the brain. For instance, understanding how neurotransmitters send messages to the neurons to be passed to the brain is part of neurobiology. Cognitive neuroscience is the study of how cognitive functions (i.e. thoughts) are dictated by neural activity. For instance, understanding the relationship between food cravings of chocolate cake and neural activity in a certain part of the brain is cognitive neuroscience. In any discipline, there are many academic journals which document the latest experimental research seeking to clarify questions and concerns in the field. One of the premier journals for neuroscience is the "Journal of Neuroscience". Often, neuroscientists who study subset specialties like neuropharmacology use this journal as a tool to keep up with advances in the greater arena of neuroscience as a whole; so that they may apply them to their own work.

The field of neuroscience is growing rapidly; with many employment opportunities resulting from the need to advance treatment options dealing with the nervous system; as well as the quest to answer historical questions on cognitive activity. Does the unconscious receive mental stimulation from the outside world?.
