"On (Not) Defining Cognition"
Synthese, 194:4233-4249

Mouse over here for a brief summary or click to open article in a new tab.I argue that cognitive scientists need not be embarrassed about their lack of a discipline-fixing definition of cognition. I advocate a pluralistic stance that eschews the categorical characterizations of cognition that some philosophers of cognitive science insist on, arguing that they are working at a level of analysis that is not important for cognitive science.

"Childhood maltreatment moderates the effect of combat exposure on cingulum structural integrity"
Development and Psychopathology, 29:1735

Mouse over here for a brief summary or click to open article in a new tab.Greater combat exposure was associated with decreased cingulum fractional anisotropy and increased cingulum radial diffusivity among individuals with more severe childhood maltreatment. Our findings provide preliminary evidence of the moderating effect of childhood maltreatment on the relationship between combat exposure and cingulum structural integrity.

"Implicit causality bias in adults with traumatic brain injury"
Journal of Communication Disorders, 71:1-10

Mouse over here for a brief summary or click to open article in a new tab.Adults with traumatic brain injury (TBI) have social communication impairments. It is not clear if these communication impairments extend to implicit social cues. Adults with TBI missed implicit social cues associated with written verbs, performing less accurately than uninjured peers. Results challenge assumptions of intact implicit processing in adults with TBI.

"The superior colliculus and the steering of saccades toward a moving visual target"
The Journal of Neurophysiology, 118:2890

Mouse over here for a brief summary or click to open article in a new tab.Are motor commands for ballistic eye movements (saccades) to stationary targets and moving targets similar? We show that motor response field features of neurons in the superior colliculus, a structure crucial for saccade generation, are altered drastically for interceptive saccades directed to a moving target.

"Glial responses to implanted electrodes in the brain."
Nature Biomedical Engineering, 1:862-877

Mouse over here for a brief summary or click to open article in a new tab.Recent evidence indicates that the supporting glial cells remodel the structure and function of neuronal networks and are an effector of stimulation-based therapy. Here, we reframe the traditional view of glia as a passive barrier, and discuss their role as an active determinant of the outcomes of device implantation.

"Understanding the inflammatory tissue reaction to brain implants to improve neurochemical sensing performance"
ACS Chemical Neuroscience, 0:00

Mouse over here for a brief summary or click to open article in a new tab.The reactivity of both microglia and astrocytes to inserted probes have been extensively studied in the past yet there remains other glial subtypes in the brain, such as oligodendrocytes and their precursors, the myelin structures they form, as well as vascular-bound pericytes, that have the potential to contribute significantly to the inflammation due to their responsibility to maintain tissue homeostasis. A brief overview of how tissue injury alters the neurochemical makeup followed by alternative potential targets of investigation and novel strategies to enhance the chemical sensing abilities of implantable probes will be discussed.

"Multi-scale, multi-modal analysis uncovers complex relationship at the brain tissue-implant neural interface: New Emphasis on the Biological Interface."
Journal of Neural Engineering, 0:00

Mouse over here for a brief summary or click to open article in a new tab.The intricacies of the biological response after implantation of brain-machine interfaces, and their ultimate impact on recording performance, remain challenging to elucidate. Here we show decreases in neural activity and blood oxygenation in the tissue surrounding the implant, shift in expression levels of vesicular transporter proteins and ion channels, axon and myelin injury, and interrupted blood flow in nearby capillaries which can impact neural activity around implanted neural interfaces.

"The Impact of Action Video Game Training on Mathematical Abilities in Adults"
AERA Open, 3:1-13

Mouse over here for a brief summary or click to open article in a new tab.Playing action video games has previously been linked to improvements in attentional control, the ability to choose what to attend and what to ignore that relies on a frontoparietal network of the brain. Here we asked whether action video game training would impact a range of mathematical abilities that rely on similar brain regions.

"Basal ganglia cerebral blood flow associates with psychomotor speed in adults with type 1 diabetes"
Brain Imaging and Behavior, online:1-8

Mouse over here for a brief summary or click to open article in a new tab.After covarying for sex, years of education and normalized gray matter volume, slower psychomotor speed was associated with lower cerebral blood flow in bilateral caudate nucleus-thalamus and a region in the superior frontal gyrus. These results suggest that the basal ganglia and frontal cortex may underlie slower psychomotor speed in individuals with type 1 diabetes.


Menekse, M., Higashi, R., Baehr, E.

"The Role of Robotics Teams’ Collaboration Quality on Team Performance in a Robotics Tournament"
Journal of Engineering Education, 106:564-584

Mouse over here for a brief summary or click to open article in a new tab.This study investigated the relationship between team collaboration quality and team performance in a robotics competition using multiple measures of team performance, including both objective task performance and expert judge evaluations, on a diverse set of supporting performance dimensions.

"A selective role for ventromedial subthalamic nucleus in inhibitory control"
eLife, 6:e31627

Mouse over here for a brief summary or click to open article in a new tab.We found that specific subsets of neurons in the subthalamic nucleus (STN) have activity consistent with causal roles in reactive stopping or switching of motor responses. Importantly, these neurons were strictly segregated to a ventromedial region of STN. Neurons in other subdivisions of the nucleus encoded task dimensions such as movement per se and proactive control.

"Local Connectome Phenotypes Predict Social, Health, and Cognitive Factors"
Network Neuroscience, 4:NA

Mouse over here for a brief summary or click to open article in a new tab.We show how subtle variability in local white matter architecture, along fascicles, reliably predicts individual differences in a number of features.
