Architecture of Neurotree.

<p><b>A,</b> Mentorship information is stored in a relational database with two core tables. The <i>person</i> table contains information about individual researchers, identified by a unique pid. The <i>connection</i> table contains information about the relationship between two people in which pid1was trained by pid2. Supplementary tables index information about institutions and research areas associated with researchers. <b>B,</b> The mentor relationships in Neurotree can be described as a directional tree in which an arrow connects a mentor to a trainee. In nearly all cases, the graph flows in a single direction without loops. In the case of collaboration, the relationship may be bi-directional. Collaborations currently represent a very small portion of the data in Neurotree.
