"Higher Cardiorespiratory Fitness is Associated with Reduced Functional Brain Connectivity During Performance of the Stroop Task"
Brain Plasticity, 5:57-67

Mouse over here for a brief summary or click to open article in a new tab.Higher cardiorespiratory fitness is associated with reduced functional brain connectivity between attentional control and visual feature centers while completing the Stroop task in a sample of young adults. Cardiorespiratory fitness may be associated with executive functioning through down-regulation of brain regions required to processing task-irrelevant stimuli.

"In vivo imaging of calcium and glutamate responses to intracortical microstimulation reveals distinct temporal responses of the neuropil and somatic compartments in layer II/III neurons"
Biomaterials, 0:0

Mouse over here for a brief summary or click to open article in a new tab.We demonstrate that increasing amplitude can increase the radius and intensity of neural recruitment, but it also alters the temporal response of some neurons. Further, dense glutamate release is highest within the first 20 μm of the electrodes site even at high amplitudes, suggesting that there may be spatial limitations to the amplitude parameter space. This ultimately suggests that increasing the amplitude of ICMS device stimulation may fundamentally alter the temporal neural response, which could have implications for using amplitude to improve the ICMS effect or offset the effects of glial scarring.

"A Year in K-12 AI Education"
AI Magazine, 40:88

Mouse over here for a brief summary or click to open article in a new tab.The time is ripe to consider what 21st-century digital citizens should know about artificial intelligence (AI).This column surveys the current state of K–12 AI education and introduces the work of the AI4K12 Initiative, which is developing national guidelines for AI education in the USA.

"Methods for an Investigation of Neurophysiological and Kinematic Predictors of Response to Upper Extremity Repetitive Task Practice in Chronic Stroke"
Archives of Rehabilitation Research and Clinical Translation, 1:100024

Mouse over here for a brief summary or click to open article in a new tab.This article presents the design, methodology, and rationale of an ongoing study to develop a predictive model of response to a standardized therapy for stroke survivors with chronic hemiparesis. Applying concepts from precision medicine to neurorehabilitation is prac- ticable and needed to establish realistic rehabilitation goals and to effectively allocate resources.
