VisualEyes: A Modular Software System for Oculomotor Experimentation

¹Department of Biomedical Engineering, New Jersey Institute of Technology

Neural control and cognitive processes can be studied through eye movements. The VisualEyes software allows an operator to program stimuli on two computer screens independently using a simple, custom scripting language. The system can stimulate tandem eye movements (saccades and smooth pursuit) or opposing eye movements (vergence) or any combination.

Axon Stretch Growth: The Mechanotransduction of Neuronal Growth

Joseph R. Loverde^1,2, Rosa E. Tolentino^1,2, Bryan J. Pfister¹

¹Departments of Biomedical Engineering, New Jersey Institute of Technology, ²Graduate School of Biomedical Sciences, University of Medicine and Dentistry of New Jersey

A unique tissue engineering method was developed to elongate numerous nerve fibers in culture by recapitulating axon stretch growth; a form of nervous system growth whereby nerves elongate in conjunction with growth of the enlarging body.

Transplantation of Schwann Cells Inside PVDF-TrFE Conduits to Bridge Transected Rat Spinal Cord Stumps to Promote Axon Regeneration Across the Gap

Yee-Shuan Lee¹, Siliang Wu², Treena Livingston Arinzeh³, Mary Bartlett Bunge^1,4,5

¹The Miami Project to Cure Paralysis, University of Miami Miller School of Medicine, ²Department of Materials Science and Engineering, New Jersey Institute of Technology, ³Department of Biomedical Engineering, New Jersey Institute of Technology, ⁴Department of Cell Biology, University of Miami Miller School of Medicine, ⁵Department of Neurological Surgery, University of Miami Miller School of Medicine

This article describes a technique to insert a hollow conduit between the spinal cord stumps after complete transection and fill with Schwann cells (SCs) and injectable basement membrane matrix in order to bridge and promote axon regeneration across the gap.

Chemistry

Probing Surface Electrochemical Activity of Nanomaterials using a Hybrid Atomic Force Microscope-Scanning Electrochemical Microscope (AFM-SECM)

Xiaonan Shi¹, Qingquan Ma¹, Taha Marhaba¹, Wen Zhang¹

¹Department of Civil and Environmental Engineering, New Jersey Institute of Technology

Atomic force microscopy (AFM) combined with scanning electrochemical microscopy (SECM), namely, AFM-SECM, can be used to simultaneously acquire high-resolution topographical and electrochemical information on material surfaces at nanoscale. Such information is critical to understanding heterogeneous properties (e.g., reactivity, defects, and reaction sites) on local surfaces of nanomaterials, electrodes and biomaterials.

VisualEyes2020 (VE2020) is a custom scripting language that presents, records, and synchronizes visual eye movement stimuli. VE2020 provides stimuli for conjugate eye movements (saccades and smooth pursuit), disconjugate eye movements (vergence), accommodation, and combinations of each. Two analysis programs unify the data processing from the eye tracking and accommodation recording systems.
