Research Interests

In general, this laboratory has been involved with basic somatosensory research and has focused on questions concerning pain and inflammation from the clinically significant temporomandibular joint.  These questions concern the contribution of nociceptors to pain and inflammation, i.e., neurogenic pain and inflammation.  In order to look at inflammation, we have been using complete Freund's adjuvant as an irritant within the rat TMJ, which results in acute and chronic inflammation.  Using this model, we have been examining how the primary neuron responds during different inflammatory conditions.  (Figure below to the right illustrates a CFA-inflamed TMJ).

This study includes three areas of the neuron, the peripheral terminals, the cell body, and the central terminals. Hutchins fig. 2 One technique that has been employed to look at these primary neurons is the superfusion technique, which is an in vitro method to analyze the release of pro-imflammatory peptides when stimulated by known irritants. Additionally, this laboratory has collaborated with others to examine the response of the TMJ to various inflammatory conditions, along with methods of rescuing the joint.  These experiments are assessed by using a computerized non-invasive behavioral technique of quantifying food intake. Therefore, it is my goal to analyze and characterize the mechanisms of the primary nociceptor during varying conditions of pain and inflammation.

As the Director of Teaching Innovations, I have been asked to explore ways in which the department can engage in educational research and develop or bring to the classroom new and engaging methods for our students.  I have started this with the design of one study on learning using interactive software.  New methods being brought to the classroom include the use of Camtasia, Audacity, and Audience Response Systems, all of which are in varying stages of use.Hutchins Fig 3

Innovative learning has also resulted in the development and publication of an interactive color atlas of the human skull in 2007.  The development of this atlas is the culmination of nearly 10 years of work, beginning with the collection of high-resolution, digital images and ending with the assimilation of the software with the student-aided design.  As an offshoot of this type of work, additional animated or elearning modules have been developed in conjunction with some of my colleagues as an adjunct to our students' learning resources.
