L11 Writing:

Write a review of the newest paper from the Berger memory prosthesis project. This paper has a lot in common with their 2013 paper, so should be a quick read.
deadwyler-hampson-song-opris-gerhardt-maramarelis-berger-2017-exp-neurol.pdf
Provide a very brief overview and then extract the data from Figure 4 and replot them in a more understandable way. This might seem a silly exercise, but is something you will need to do frequently with published results. Concentrate only on the mean values; ignore standard error and significance marks. Be reasonably accurate when extracting the data.

For Tuesday, May 2, 2017: assessment techniques.

L9 Reading:

The first paper is a review of visual performance assessment written by Dagnelie, and formed the basis of the lecture.
dagnelie-2008-annual-rev-bioeng.pdf

These other three papers should be read for measurement technique more than results. Pay particular attention to any missing control conditions or factors that would affect reproducibility.
nau-bach-fisher-2013-trans-vis-sci-tech.pdf
thomspon-barnett-humayun-dagnelie-2003-iovs.pdf
dagnelie-et-al-2017-clinical-exp-ophthalmol.pdf

We'll be re-reading the following papers for technique (not results):
bourkiza-vurro-jeffries-pezaris-2013-plos-one.pdf
vurro-crowell-pezaris-2014-front-human-neurosci.pdf
stingl-bartz=schmidt-besch-et-al-zrenner-2013-proc-royal-soc-b.pdf
zhou-dorn-greenberg-et-al-2013-ieee-icmew.pdf
duret-brelen-lambert-gerard-delbeke-veraart-2006-restorative-neurol-neurosci.pdf

The following papers were mentioned in passing, and can be considered optional:
Eccentric reading: sommerhalder-oueghlani-bagnoud-leonards-safran-pelizzone-2003-vis-research.pdf
Checkers: srivastava-troyk-dagnelie-2009-j-neural-eng.pdf
Navigation: cha-horch-normann-1992-annals-biomed-eng.pdf
Line following / door task: zhou-dorn-greenberg-et-al-2013-ieee-icmew.pdf

At the start of class, we went over the following two papers that introduced the idea of magnetic stimulation instead of electrical stimulation. As you read them, do not worry about the details surrounding the electrical field modeling (they can be skipped). Concentrate instead on the neural responses.
lee-fallegger-casse-fried-2016-sci-adv.pdf
bonmassar-lee-freeman-polasek-fried-gale-2012-nature-comm.pdf

L9 Writing:

Come up with a new way to map phosphenes for each of low (less than 20), medium (20-100), and high (100-1000) density artificial vision. Do not use any methods from the literature (e.g., pointing, describing clock positions). Propose one method for each condition, or a single method that covers all three. It will help tremendously to imagine what the patient would perceive with an erroneous map, and how the patient would interact with your proposed measurement system. Consider that a given patient will be able to concentrate for 20-30 minutes at a time, and that their responses will be inherently variable and only mostly truthful due to lapses in attention.

Assume any existing facility worldwide is at your disposal. Any device or apparatus you can imagine based on existing technology is OK, but no magical new technology (like, say, mind reading) is allowed. Invasive instruments beyond the implant itself are discouraged, but the implant can be augmented if it would help.

The length of your write-up should be about as long as a normal homework review.




For Tuesday, April 25, 2017: sensory substitution.

L8 Reading:

The papers this week are relatively easy reading, as they are mostly high-level reviews of existing projects for sensory substitution methods which end up being mostly low-grade, and so are called electronic travel aids.

ortiz-et-al-2011-plos-one.pdf

L8 Writing:

Write a mini-review of the Merabet, et al., 2008 paper.

Communicating with clarity (Tufte excerpts, Katzoff book):

Here is an excerpt from Edward Tufte's book that was discussed in the first part of class.

tufte-1997-visual-and-statistical-thinking.pdf

And here are two additional PDFs from Tufte that are available, although purchase of the hardcopy of The Visual Display of Quantitative Information is highly recommended.

tufte-2006-powerpoint.pdf
tufte-1974-data-analysis-for-politics-and-policy.pdf

And finally, here is a famous publication from Sam Katzoff, technical writing guru at NASA, about writing technical reports that applies quite well to writing scientific articles as well.

katzoff-1964-clarity-in-technical-writing.pdf




For Tuesday, April 4, 2017: cortical approach.

L7 Reading:

Brindley and Lewin's classic work:
brindley-lewin-1968-j-physiol.pdf

Dobelle:
dobelle-2000-asaio.pdf

bradley-troyk-berg-bak-cogan-erickson-kufta-masaro-mccreery-schmidt-towle-xu-2005-j-neurophsiol.pdf

L7 Optional Reading:

schiller-tehovnik-2008-perception.pdf This is a controversial paper that goes into much detail, arguing that cortical prostheses are the most compelling approach. It raised an unusual amount of ire, resulting in the publication of two highly critical responses by other researchers.

naumann-2012-search-for-paradise.pdf This is a very long book. While it is worth reading the whole text, the most relevant part for the course is Chapter 9. Read it over Easter break!

christie-ashmont-house-greger-2016-j-neural-eng.pdf This is a nice review of retinal and especially cortical efforts, making the argument that investigation with cortical surface microelectrodes should continue.

L7 Optional Video:

We saw the first few minutes of Blind Hope during class. The whole video is about 45 minutes long. There is a lot of overlap with Naumann's book, and reading it first can provide significant insight when hearing Dobelle speak.

L7 Writing:

Write a mini-review of the Bradley, et al., 2005 paper. Read the entire paper, but don't worry about the electrode details or histology. Concentrate your analysis on Figures 9 and 10.




For Tuesday, March 28, 2017: retinal (iii), and optic nerve approaches.

For Tuesday, February 28, 2017: causes of blindness, electrical approaches to visual prosthetics.

L2.1 reading:
Vision 2020. Despite being a very large document, it is a quick read. Read through page 8; after that is optional. Also read Thylefors, et al., 1995 on the demographics of blindness, and Mader, George, 2006 on war-time trauma.

Optional reading:
Jackson, 1996 on landmine blindness, Theylefors, 1992 on the demographics of ocular trauma, and Bell, Mino, 2015 on employment outcomes of the blind.

L2.2 reading:
Read Goetz, Palanker, 2016 for an excellent overview of electrical approaches to visual prosthetics.

L2.2 writing:
Read Pezaris, Eskandar, 2009, and dissect it completely. Find all of the flaws. Tear it to pieces. Do not hold back just because it was written by the lecturer.




For Tuesday, February 21, 2017: the early visual system, structure of the retina, and coordinate transformations in the visual system.

Read Hubel, "Eye Brain Vision", 1995 . This is a long, fascinating book by one of the founders of the field of Neurobiology, the late Nobel laureate David H. Hubel. You should skim it to familiarize yourself with background material on the early visual system, concentrating on Chapters 3 and 4. In addition to the PDF linked above, used copies of this out-of-print text are readily available (see, for example, bookfinder.com).

Read the review paper Andersen, Snyder, Li, Stricanne, 1993 on coordinate transformations first, and then the experimental report Andersen, Bracewell, et al, 1990 that contains one component of the review. The written assignment will be drawn on these two papers that introduce the idea of gain fields as a representational mechanism for adapting the center-surround response field to a coordinate system that includes other non-retinal position (eye-in-head, head-on-body, body-in-space) inputs.

For the writing assignment: read the entire second paper (Andersen, Bracewell, et al, 1990), but in your review concentrate on Figures 4 and 6; don't worry about the details in the second half of the paper where they talk about the different kinds of planar fits (Figures 7 and onward; but do look at Figure 14 for a putative model). See the Homework section of the main course page for specific instructions on the mini-review format.

For background on the non-uniform resolution of visual representation as it originates in the eye, read Curcio, Sloan, Kalina, Hendrickson, 1990 for the topography of photoreceptors in the human eye, and Curcio, Allen, 1990 for the topography of human retinal ganglion cells (the output of the retina, the axons of which form the optic nerve). Randall Munroe's XKCD comic on visual acuity can be found at https://xkcd.com/1080/large.
