“Neurometrics: Resting-state qEEG Predicts Second Language (L2) Learning as well as a Standardized Language Aptitude Test” (Chantel Prat):
Decades of research using fMRI and EEG have shown that properties of network-level brain functioning at rest can be used to characterize individual differences in a variety of cognitive abilities. My current work explores the predictive utility of various characterizations of brain function using quantitative EEG (qEEG), resting-state fMRI, structural MRI, task-related fMRI, and psychometric tests of cognitive abilities for understanding individual differences in L2 learning. In the current talk, I’ll describe a study showing that 5 minutes of eyes-closed resting-state qEEG data can predict L2 learning as well, or better, than a standardized language aptitude test that takes a bit over an hour to administer. Future directions include the development and testing of neurometric assessment tools for predicting subsequent complex behaviors.
“Linking the statistics of network activity and network connectivity” (Eric Shea-Brown):
There is an avalanche of new data on the brain’s activity, revealing the collective dynamics of vast numbers of neurons. In principle, these collective dynamics can be of almost arbitrarily high dimension, with many independent degrees of freedom — and this may reflect powerful capacities for general computing or information. In practice, datasets reveal a range of outcomes, including collective dynamics of much lower dimension — and this may reflect the structure of tasks or latent variables. For what networks does each case occur? Our contribution to the answer is a new framework that links tractable statistical properties of network connectivity with the dimension of the activity that they produce. I’ll describe where we have succeeded, where we have failed, and the many avenues that remain.

The November 2017 UWIN seminar features a fascinating pair of short talks by UWIN faculty members Sawyer Fuller and Wyeth Bair:
- “Fly-inspired visual flight control of insect-sized robots using wind sensing”
Sawyer Fuller, Assistant Professor, Department of Mechanical Engineering, University of Washington
- “Comparing shape representation in mid-level visual cortex to that in a deep convolutional neural network”
Wyeth Bair, Associate Professor, Department of Biological Structure, University of Washington
The seminar is on Wednesday, November 8th, 2017 at 3:30pm in Husky Union Building (HUB) 337. Refreshments will be served prior to the talks.
“Fly-inspired visual flight control of insect-sized robots using wind sensing” (Sawyer Fuller):
In the Autonomous Insect Robotics Laboratory at the University of Washington, one of the projects we are interested in is how to give robots the size of a honeybee the ability to fly themselves autonomously. Larger drones can now do this task, but they use sensors that are not available in insect-sized packages, like the global positioning system and laser rangefinders. We are left with sight, the same modality used by flies. But visual processing is typically computationally intensive. I will describe research I performed on flies that reveals that they overcome this by combining slow feedback from vision with fast wind feedback, and discuss ramifications for our robots.
“Comparing shape representation in mid-level visual cortex to that in a deep convolutional neural network” (Wyeth Bair):
Convolutional neural nets (CNNs) are currently the best performing general purpose image recognition computer algorithms. Their design is hierarchical, not unlike the neural architecture of the ventral visual pathway in the primate brain, which underlies form perception and object recognition. We examined whether units within an implementation of “AlexNet” (Krizhevsky et al., 2012), following extensive supervised training, end up showing selectivity for the boundary curvature of simple objects in an object-centered coordinate system, similar to that found for neurons in the mid-level cortical area V4 (Pasupathy and Connor, 2001). I will show how the units in AlexNet compare to those in V4 in terms of shape-tuning and translation invariance and will discuss the benefits and limitations of comparing complex artificial neural networks to the brain.
We are extremely proud to announce that two UWIN faculty members, Bing Brunton (Biology) and Steve Brunton (Mechanical Engineering) have each won an AFOSR Young Investigator Research Program Award!

UWIN seminar resumes for the 2017-18 academic year! The October 2017 UWIN seminar features an exciting pair of short talks by UWIN faculty members Chet Moritz and John Tuthill:
- “Neural devices to promote plasticity and recovery following spinal cord injury”
Chet Moritz, Associate Professor, Departments of Rehabilitation Medicine, Physiology & Biophysics, University of Washington
- “Neural coding of leg proprioception”
John Tuthill, Assistant Professor, Department of Physiology & Biophysics, University of Washington
The seminar is on Wednesday, October 11th, at 3:30pm in Husky Union Building (HUB) 337. Refreshments will be served prior to the talks.
“Neural devices to promote plasticity and recovery following spinal cord injury” (Chet Moritz):
Neural devices have tremendous potential to improve quality of life after spinal cord injury. Both intraspinal and transcutaneous stimulation can activate neural circuits distal to an injury, leading to either direct muscle contraction or facilitating therapy enabling volitional movements. A recent case study of cervical transcutaneous stimulation resulted in both immediate and sustained improvements in hand and arm function. A participant with chronic C3 tetraplegia (ASIA D) improved nearly all measures of hand motor function tested after only 4 weeks of skin surface stimulation paired with physical therapy. Physical therapy alone did not lead to further improvements, but benefits were sustained over a three month follow-up period without further treatment.
“Neural coding of leg proprioception”(John Tuthill):
Proprioception, the sense of self-movement and body position, is critical for the effective control of motor behavior. We have developed new methods to record from genetically-identified neurons in proprioceptive circuits of the fruit fly, Drosophila, using 2-photon calcium imaging and patch-clamp electrophysiology. I will discuss our initial attempts to understand proprioceptive neural coding in cells and circuits that sense leg movement and position. I will also discuss how these proprioceptive feedback signals are used by motor circuits that control leg muscle activity and behavior.
