Two members of the Purdue Institute for Integrative Neuroscience, Dr. Chris Rochet, and Dr. Riyi Shi recently discover a key factor in the development of Parkinson’s disease that could lead to new therapies, potentially including drugs currently on the market. This discovery could facilitate earlier diagnosis and prevention of the neurological disorder.

Advancements in microfabrication has enabled manufacturing of microscopic neurostimulation electrodes with smaller footprint than ever possible. The smaller electrodes can potentially reduce tissue damage and allow better spatial resolution for neural stimulation. Although electrodes of any shape can easily be fabricated, substantial effort have been focused on identification and characterization of new materials and surface morphology for efficient charge injection, while maintaining simple circular or rectangular Euclidean electrode geometries. In this work we provide a systematic electrochemical evaluation of charge injection capacities of serpentine and fractal-shaped platinum microelectrodes and compare their performance with traditional circular microelectrodes. Our findings indicate that the increase in electrode perimeter leads to an increase in maximum charge injection capacity. Furthermore, we found that the electrode geometry can have even more significant impact on electrode performance than having a larger perimeter for a given surface area. The fractal shaped microelectrodes, despite having smaller perimeter than other designs, demonstrated superior charge injection capacity. Our results suggest that electrode design can significantly affect both Faradaic and non-Faradaic electrochemical processes, which may be optimized to enable a more energy efficient design for neurostimulation.

As part of its Integrative Data Science Initiative, Purdue is launching an internal funding opportunity for ambitious proposals that apply data science to pressing, socially relevant issues. The funding will leverage the University's existing strengths in data analytics to help position Purdue as a leader in science-enabled research, says Tomás Díaz de la Rubia, chief scientist and executive director of Discovery Park, who is spearheading the research thrust of the initiative.

As part of its Integrative Data Science Initiative, Purdue is launching an internal funding opportunity for ambitious proposals that will expand data science education across campus. Initiated by Jay Akridge, provost and executive vice president for academic affairs and diversity, and Suresh Garimella, executive vice president for research and partnerships, the initiative has been formulated through two cross-campus working groups, forums and input from campus-wide discussions.

Richard van Dijn from the Purdue College of Pharmacy, along with Meridith T. Robins, Terrance Chiang, Kendall L. Mores, and Doungkamol Alongkronrusmee have explored the hypothesis that dorsal striatal Gi/o-protein activation is sufficient to reduce voluntary alcohol intake. Using a voluntary, limited-access, two-bottle choice, drink-in-the-dark model of alcohol (10%) consumption, they validated the importance of Gi/o signaling in this region by locally expressing neuron-specific, adeno-associated-virus encoded Gi/o-coupled muscarinic M4 designer receptors exclusively activated by designer drugs (DREADD) in the dorsal striatum and observed a decrease in alcohol intake upon DREADD activation. Overall, these results suggest that activation Gi/o-coupled GPCRs expressed in the dorsal striatum, such as the DOR, by G-protein biased agonists may be a potential strategy to decrease voluntary alcohol consumption and ?-arrestin recruitment is to be avoided.
