We have three openings tenure-track faculty positions in “Translational Neuroscience” here at CCNY encompassing clinical, basic, and computational neuroscience. The home department for each position is fairly flexible, though we envision one hire in Biomedical Engineering, one in Psychology and one in the Medical School. Joint appointments with Math, Biology, etc. are also possible. The search will consider all ranks from Assistant to Full professor.

Please also distribute this announcement to students or collaborators who may be interested.

PRISM Lecture/Neuroscience joint talk:

“The tongue as visual surrogate: experiences with sensory substitution for blindness”


University of Pittsburgh School of Medicine

Tuesday April 30, 2013, Time: 12:35 – 1:45 PM  Location: NAC 7/236 

Abstract: Sensory substitution is a newer concept for restoring a sense of the environment to the completely blind.  How to test performance for states of ultra low vision in the context of artificial vision, particularly those mediated through non-visual pathways is a new area of research.  This lecture will provide an overview of experiences using the BrainPort and some method to conduct objective and quantifiable assessments of behavioral performances.  In addition, preliminary results of neuroimaging studies using diffusion tensor MR imaging (DTI) and functional positron emission tomography (PET) will be shown to suggest that the visual brain becomes less organized as a function of blindness duration.

Biography: Dr. Nau is the Director of optometric and low vision services for the UPMC Eye Center, and the founder of the Sensory Substitution Laboratory at the University of Pittsburgh. She graduated from the New England College of Optometry and completed a residency in ocular disease at the VAMC in Boston. She practiced at the Beth Israel Deaconess Hospital in Boston for five years and has been at the University of Pittsburgh since 2003.  Clinically, she specializes in medical contact lenses for ocular surface and corneal disease, including scleral lenses and contacts for artificial corneas. Her research interests primarily center on artificial vision technologies for the blind, including sensory substitution. Her laboratory has conducted the largest human studies to date of the BrainPort Vision Device, which uses the tongue as a means to convey visual information to the brain.

UPDATE.  All three candidates passed the thesis defenses!  We are very proud of outstanding projects and presentations.

10:30 AM  “A novel visual stimulation paradigm: exploiting individual primary visual cortex geometry to boost steady state visual evoked potentials (SSVEP).” MS Candidate MARTA ISABEL VANEGAS ARROYAVE.  Advisor: Prof. Simon Kelly. Location: Steinman BME 5th Floor conference room

12:00 PM “Finite Element Study of transcranial Direct Current Stimulation: customization of models and montages.” MS candidate DENNNIS Q. TRUONG. Advisor: Prof. Marom Bikson, Location: Steinman Room 2M13 (floor 2M)

1:30 PM  “Design, Product Development, and Risk Assessment of Tin (Sn) ring electrodes as a substitute to Silver-Silver Chloride (Ag/AgCl) ring electrodes for High Definition – transcranial Direct Current Stimulation (HD-tDCS).” MS Candidate LINFORD LEITCH, Location: Steinman Room 2M13 (floor 2M)

3:00 PM  Picture time.  Please meet right in front of Steinman Hall and please be prompt, as we will take pictures right away (if it rains meet in Neural Engineering).  Because we have not updated our picture in years, current and PAST lab members should come.  Please spread the word to everyone (since not everyone might be on the mailing lists).   All students, volunteers, lab affiliates should come.
