Established in 1891, JCN is the oldest continually published basic neuroscience journal. Historically, as the name suggests, the journal focused on a comparison among species to uncover the intricacies of how the brain functions. In modern times, this research is called systems neuroscience where animal models are used to mimic core cognitive processes with the ultimate goal of understanding neural circuits and connections that give rise to behavioral patterns and different neural states.Research published in JCN covers all species from invertebrates to humans, and the reports inform the readers about the function and organization of nervous systems in species with an emphasis on the way that species adaptations inform about the function or organization of the nervous systems, rather than on their evolution per se.JCN publishes primary research articles and critical commentaries and review-type articles offering expert insight in to cutting edge research in the field of systems neuroscience; a complete list of contribution types is given in the Author Guidelines. For primary research contributions, only full-length investigative reports are desired; the journal does not accept short communications.

JCN成立于1891年，是最古老的連續出版的基礎神經科學雜志。從歷史上看，正如它的名字所暗示的那樣，該雜志關注的是物種之間的比較，以揭示大腦功能的復雜性。在現代，這項研究被稱為系統神經科學，動物模型被用來模擬核心的認知過程，最終目的是理解導致行為模式和不同神經狀態的神經回路和連接。研究發表在JCN涵蓋所有物種從無脊椎動物到人類,和報告告知讀者在物種的神經系統的功能和組織強調物種適應性的方式通知的功能或神經系統的組織,而不是在他們的進化本身。JCN發表主要的研究論文、評論和評論類文章，為系統神經科學領域的前沿研究提供專家見解;在作者指南中給出了一個完整的貢獻類型列表。對于主要的研究貢獻，只需要完整的調查報告;期刊不接受短訊。
