Nature Communications, 2020 Brain ischemia has been associated with deficits in neural oscillations. Here in an animal model, the authors show that modulation of low-gamma oscillations using a light flicker can restore low gamma oscillations and protect ischemic neurons.

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability
Advanced Materials Technologies, EarlyView.ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

Brain oscillations reflecting pain-related behavior in freely moving rats
Pain, 2017 Recording oscillatory brain activity holds great promise in pain research. However, experimental results are variable and often difficult to reconcile. Some of these inconsistencies arise from the use of hypothesis-driven analysis approaches that (1) do ...

The role of brain oscillations in predicting self-generated sounds
NeuroImage, 2017 Being able to predict self‐generated sensory consequences is an important feature of normal brain functioning. In the auditory domain, self‐generated sounds lead to smaller brain responses (e.g., auditory evoked responses) compared to externally ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Altering alpha-frequency brain oscillations with rapid analog feedback-driven neurostimulation.
PLoS ONE, 2018 Oscillations of the brain's local field potential (LFP) may coordinate neural ensembles and brain networks. It has been difficult to causally test this model or to translate its implications into treatments, because there are few reliable ways to alter ...

Controlling the Temporal Structure of Brain Oscillations by Focused Attention Meditation
Human Brain Mapping, 2018 Our focus of attention naturally fluctuates between different sources of information even when we desire to focus on a single object. Focused attention (FA) meditation is associated with greater control over this process, yet the neuronal mechanisms ...
