International Journal of Comparative Psychology

Within the broad domain of neuroscience there is a divergence between those journals that focus on human clinical topics and those that take a decidedly comparative evolutionary and nonhuman approach. This distinction reflects a deeper separation between two branches of neuroscience: the human neuropsychological and the comparative neuroscience fields. I argue that this divergence is a reflection of scala naturae thinking and that greater strides in scientific thinking can be gained by overcoming this bias in favor of deep continuity across the human and nonhuman subdomains of neuroscience.
