This introduction to the Association for the Rhetoric of Science & Technology’s (ARST) twentieth anniversary special issue of Poroi reflects on the inventional resources for scholarship concerning the rhetoric of science, technology, and medicine (RSTM).

Catchy but charged headlines such as "Obese Teens May Be Lacking in Brain Size, Not Willpower" These popular accounts present rhetoric scholars with numerous opportunities for interrogating scientific understandings of the brain and their development through the discourses, practices, and materials of neuroscience. However, a strictly deconstructive approach, as Bruno Latour (2004) notes, can be viewed as intellectually hostile to the efforts of scientific researchers (p. 225-228). Because neuroscience is a relatively new and diverse field, it is important to
