									         BMED 8813 IC2: Spatial and Temporal Scales in the Nervous System
          Spring 2009 – Profs. Shella Keilholz (SK) and Garrett Stanley (GS)


Introduction

M Jan 05       Course Introduction – GS and SK

In class: Pass out syllabus, make clear the overall goals of the course, the logistics of
Modules 1, 2, and 3, introduce ourselves, have members of class introduce themselves,
discuss the previous IC course, discuss expectations (familiarity with Matlab, etc)

Assignment: Read syllabus and check out course website


              MODULE 1 – Spatial and Temporal Scales of Early Vision


W Jan 07       Introduction to Module 1 – GS

In class: Module 1 - introduce the perspective of visual art as a sampling problem,
illusions, break into small groups to discuss, example illusion presentation

Form Groups: small groups for discussion, larger groups for presenting motion/time
illusions, draw from a hat for the particular illusion you will present, look up resources
and take best guess at what is causing phenomenon (note that some of these will be
spatial, some temporal, and mostly a combination – the goal here is to simply get us
thinking about these things).

Assignment: Read Perspective paper from Conway & Livingstone (2007), individuals
each visit Illusion website (http://www.michaelbach.de/ot/) and experience at least 5 of
these phenomena and write 2 or 3 sentences about your observations of each to turn in
during next class meeting, each group prepare presentation on illusion assigned for next
class meeting

Resources: Conway and Livingstone (2007), http://www.michaelbach.de/ot/, Dr.
Angry/Mr. Smile movies, etc.

handing in during next class meeting, Read SchynsOliva1998 paper, Assignment 1 - do
sampling exercises in groups

Resources: http://www.michaelbach.de/ot/, Dr. Angry/Mr. Smile movies, etc.,
Castleman chapters, some basic Matlab scripts to lead in the right direction

Anatomical Predictions of Spatial Fidelity

M Jan 26       Implications of Retinal Sampling

In class: Groups present the anatomical findings, to turn in short (1 page) writeup of
anatomic findings at next class meeting, break into new small groups for open discussion
on the implications of the findings, ask whether known anatomy predicts spatial fidelity
of early vision, propose explicit experiments to more rigorously test this, revisit the Dr.

characteristics they used, revisit the Mona Lisa and make predictions about distance
observer should stand relative to the painting
