Taylor Mighell, current NGP student, receives the CW Cotterman Award for best article.

Taylor Mighell, NGP graduate student in Brian O'Roak's lab, was presented with C.W. Cotterman Award at the American Society of Human Genetics meeting in October. Each September, the editorial board of The American Journal of Human Genetics selects two articles published in the journal in the previous year that best represent outstanding scientific contribution to the field of human genetics. Taylor's award is in recognition of his manuscript that was published in May entitled, "A Saturation Mutagenesis Approach to Understanding PTEN Lipid Phosphatase Activity and Genotype-Phenotype Relationships." Great work, Taylor!

Marc Meadows receives an award to attend the biannual Federation of European Neuroscience Societies Forum.

Marc Meadows was 1 of 15 trainees to receive a $2,000 award to attend the biannual Federation of European Neuroscience Societies (FENS) Forum held in Berlin, Germany in July 2018.  He presented his research on exo- and endocytosis at an inhibitory synapse in the retina. The scope of Marc's work has broad impacts on our understanding of inhibitory synaptic vesicle dynamics and the pre-processing of visual information. Congratulations, Marc!

Current student, Nate Yoder, publishes article in Nature.

Congratulations to NGP student, Nate Yoder on his new paper in Nature

For the first time, researchers in the Vollum Institute have determined the atomic structure of an acid-sensing ion channel (ASIC) in a resting state at high pH.  ASICs are expressed in neurons throughout the nervous system and contribute to a variety of neurological processes including pain sensation and fear memory formation. ASICs populate three functional states, existing in a resting state at high pH, opening in response to low pH and desensitizing within milliseconds. In their manuscript, published recently in the journal Nature, Yoder, Yoshioka and Gouaux used a combination of x-ray crystallography and single-particle cryo-electron microscopy to determine the structure of the resting channel. Additionally, the authors were able to determine the molecular mechanisms that allow the channel to respond to changes in pH by comparing the structure of the resting channel with those of the channel in open and desensitized states published in 2014 and 2009, respectively. These findings improve our understanding of how the nervous system responds to pH and provide a blueprint for the design of molecular agents to aimed at targeting these channels.

Title:  Bats possess the molecular and anatomical substrate for laryngeal motor cortex

Authors:  Alex Nevue, Peter Lovell, Claudio Mello and Christine Portfors

Language is learned when we are young through a process called imitative vocal learning. Vocal learning requires precise connections between auditory and motor pathways of the brain that enable children to listen and match speech from an adult tutor. The vocal learning process can be shunted by a variety of communication disorders including autism and stuttering. Because vocal learning is so rare, there currently is not a model organism to study it in mammals. Bats have shown some behavior suggesting that they are vocal learners, so we asked if bats possess the neural circuitry required to learn and produce sounds. Using neuronal tracing and gene expression techniques, we found a specialization in the motor cortex of bats that is involved in producing learned vocalizations. Bats are the first non-human mammal that we know to possess this specialization. This research suggests that bats may serve as a useful animal model to study human speech and language disorders.

Oregonian highlights researchers at the Oregon Health Research Center

The Oregon Hearing Research Center (OHRC) at OHSU is a world leader in studies of auditory neuroscience, ranging from cochlear development to cortical processing.  Many OHRC faculty have joint appointments in the Vollum Institute as well.  An article in today's Oregonian highlights that a number of OHRC faculty are themselves hearing impaired, and so students in NGP learn about hearing disorders and their treatments from lecturers with first-hand experience.  Read today's front page Oregonian article.

Maria Purice publishes in Nature Communications

Glia perform important immune functions to defend the brain against toxic insults and minimize damage after injury. In the aging brain, it has been proposed that changes in glial immunity may be related to the onset of some neurodegenerative diseases. We used a well-established acute axotomyassay in Drosophila to examine how key features of glial immunity are altered with age. Our studies show that in the aging brain glial engulfment of neurodegenerative material is dysfunctional due to down regulation of the Draper receptor at the protein level, as a result of decreased PI3K92E activity and translation efficiency. Additionally, we demonstrate that aged Drosophila olfactory nerves are delayed in initiating Wallerian degeneration after injury, similar to what has been previously shown in mammals. However, increasing Draper/PI3K92E activity in the aging brain was sufficient to rescue both reduced Draper expression and delayed glial clearance of severed axons after injury. This work highlights reduced glial engulfment activity as an intriguing candidate mechanism for age-related vulnerability to neural damage and disease.  Congratulations to Maria Purice on her important publication in Nature Communications!

Danielle Robinson receives Mozilla Fellowship

We are proud to announce that Danielle Robinson, a PhD candidate in the Neuroscience Graduate Program, has been awarded a 2016 Mozilla Fellowship for Science. This highly competitive program supports the work of early career researchers who want influence the future of scientific communication and data sharing within their communities. Already a student leader in this area, Danielle has championed digital literacy, openness, and collaboration as a co-organizer of Open Insight PDX and Science Hack Day Portland. She is also a founding member of Women in Science Portland. 

Throughout her fellowship year, Danielle will receive support from Mozilla to hone her skills, lead outreach initiatives, and develop local resources around open source, data sharing, and science policy through mentorship at Mozilla, the OHSU Library, and the OHSU School of Medicine. We are excited that Danielle will be able to grow her work as thoughtful and passionate advocate for open science, collaborating with OHSU faculty, students, and administrators to support the knowledge and practices that are key to the creation and communication of impactful research.

Congratulations Danielle!
