Flexible fibers for optoelectronic probing of spinal cord circuits
The majority of the neural engineering efforts in the past decade have focused on brain interfaces. The searching of tools for recording and modulation of neural activity in the spinal cord limits fundamental understanding of neural dynamics in this organ. Spinal cord poses a challenge to probe …

Penetration force measurements in the central nervous system with silicon electrodes
One of the major challenges in neural engineering is the tissue damage that occurs during insertion of microelectrodes into the central nervous system. The damage occurs as a result of the dimpling effect that is due to the insertion force. A method which can reduce the penetration force can also …

Multifunctional fiber-based neural interfaces
… However, our ability to understand and to treat neural disorders is currently limited by the lack of tools capable of interfacing with the brain over extended periods of time. This is hypothesized to stem from the mismatch in mechanical and chemical properties between the neural probes and the …

Translational Modeling of Non-Invasive Electrical Stimulation
<p>Seminal work in the early 2000’s demonstrated the effect of low amplitude non-invasive electrical stimulation in people using neurophysiological measures (motor evoked potentials, MEPs). Clinical applications of transcranial Direct Current Stimulation (tDCS) have since proliferated, though the …

Effects of Dip-coated films on the Properties of Implantable Intracortical Microelectrodes
<p>The successful clinical use of implantable intracortical microelectrodes (ICMs) to treat certain types of deafness, blindness, and paralysis is limited by a reactive tissue response (RTR) of the brain. This RTR culminates in the formation of a tight glial scar and a loss of neuronal density …

Influence of transdermal current flow in tDCS-induced cutaneous adverse events
<p>Significant contributors to the broad application of transcranial direct current stimulation (tDCS) are portability, ease-of-use, and tolerability; with adverse events limited to transient and mild cutaneous sensations (e.g. perception of burning, itching, and tingling) and erythema. However, …

A brain-machine interface for investigating neural representations of navigation in a virtual environment
Simultaneously recording behaviour and neural activity can only take researchers so far in understanding the function of different regions of the brain, and the neurons therein. Novel methods are required for probing further beyond standard correlational and knockout analysis. The activity of one …

Addressing Indirect Functional Connectivity in Neuroscience via Graphical Information Theory: Causality and Coherence
… non-Gaussian cases, which are more relevant for neural data. Previous model-free methods have limited ability to identify indirect connections because of inadequate scaling with dimensionality. This poor scaling performance reduces the number of nodes, e.g. brain regions, that can be included in …
