The data collected in this study will provide insight in the development of a muscle model while the muscle is in the lengthening mode.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

Consequently, there exists a significant need for alternative types of treatment. To aid in the effort of solving this problem, the authors have developed a prototype system that will monitor neuron activity to detect a seizure and terminate seizures in their initial stages. The system consists of 3 blocks: a data acquisition system, a seizure detection unit, and a stimulation device. The data acquisition system includes a detector implanted in the brain. This detector collects raw electrical waveforms that are filtered for the presence of neural action potentials by special signal processing equipment. The quantity and frequency of these neural action potentials is sent to the seizure detection unit, which employs a specially designed algorithm to detect pre-seizure activity in single neuron firing patterns. If the presence of pre-seizure activity is discovered, the seizure detection unit sends a signal to the stimulation device, which emits an electrical signal into the brainstem, thereby preventing a full seizure. This prototype is tested in rats treated with pentylenetetrazol (PZT) a known seizure inducing drug.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

These effects prolong surgery and interfere with effective coagulation. New instruments are described that remove heat from the tips thereby maintaining their temperature below the sticking temperature. These cooled instruments cauterize normally but eliminate sticking and reduce char and smoke formation. These instruments are fabricated using heat pipes that passively dissipate heat along their length via natural convection. Infrared imaging is used to characterize performance and optimize electrode heat transfer surface area. In-vivo animal testing demonstrates excellent haemostasis while eliminating sticking. These new instruments may speed surgery and enable new applications for electrocautery.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

The authors introduce the use of CLEAN, a nonlinear deconvolution algorithm, to cancel coherent sidelobes in OCT images of extracted human teeth.
