Course Activities/Assignments/Requirements


4 Exams. Each exam will be based on material from the class lectures and the textbook. Before each exam, I will be passing out a sheet of essay questions that the exam will be based on. All exams are a combination of short answer and essay questions. Each exam will be worth 100 points (8 out of ? short answer and 2 out of 3 essays). MAKE-UP POLICY: If for some reason you must miss a test, you must notify me as soon as possible (either by telephone, e-mail, or stopping by). You need to have a valid excuse that can be verified by documentation (Gee, I forgot is NOT a valid excuse). You must take it BEFORE I give back the exams to the class and you must take it on the date and time that we decide (no making up the make-up). You cannot make up the test during class time and you cannot have more that one make-up exam.

Attendance: While I do not have a strict attendance policy, it is expected that you will attend class regularly. If for some reason you miss a class, it is your responsibility to find out any information that was discussed in class. When in class, I ask that you be courteous to myself and to others. Refrain from constant chit-chat, note-passing, and playing around on the computer. If you come in late or plan on leaving early, sit near the door so as not to disturb others. Please make sure your cell phones are off and beepers on vibrate. In addition, I can see when you are doing other work besides mine - I don’t want to see it. It is especially annoying when people who are doing other things then ask questions that obviously indicate they were not paying attention. My other pet peeve is when people walk into class late and want to turn something in or pick something up after I start class. Again, don’t do that, please.

One final note - if you are having difficulty, do not wait until the end of the semester to come talk to me and plead for me to give you a C when your grade is an F or to give you extra credit. Please talk to me as soon as possible if you are having personal difficulties or are having a problem with course material. Midterm is Oct. 8.

Special Needs Statement: VSU, in accordance with the Americans with Disabilities act will make accommodations for students who require special assistance because of a disability. If you require some assistance, do not hesitate to make me aware of your situation, but you must also register with Special Services in Nevins Hall.

How the nervous system works (To help answer question 2)
This is site that gives basic neural anatomy and how it works.
Here is a biopysch tutorial page

This is a group of pictures and sounds of a spinal cord neuron responding to various stimuli strengths.

*Some basic pictures and notes1 and notes2 about the neuron and the brain.

Psychophysics / Ch 2
Still lost with Signal Detection Theory? Here are some detailed notes from Stanford. Here is another site with some descriptions and an experiment or try the tutorials. Here is a website that shows how it is used to study search engines. And another that applies it to memory. And the picture that I showed you in class - is it Mary (S+N) or a waterstain (N)?

*Some basic notes about psychophysics

The visual system / Ch 3
*Some basic notes about light and the eye
*Differences between rods and cones and parvo and magno cells.
*Some notes about the brain pathway
For a discussion on the wave properties of light (including reflection, etc.), look here. This site contains a discussion on color mixing (additive and subtractive)

If you want eye diagrams, explanations of color vision, description of dark adaptation, try The Joy of Visual Perception. This is a web book all about vision. Or, try dissecting a cow's eye on your own.

Some wonderful examples of how our brain "fills in" our blind spot. This really demonstrates top down processing (make sure you try out ALL of the examples).

Receptive fields don't make any sense to you? Check out Sensation and Perception tutorials. It has info on receptive fields of the eye and the brain. If that still didn't help, try this site.

More information on various visual disorders as well as a bunch of useful links can be found at the Kanolinska Institutet. The A.A.O./Eyecare America has a list of useful websites and materials and a museum of vision.

Liden's site Visionary contains term definitions and even has a section with a brief description on the cortical areas of the brain. If the buttons don't appear on the side (you just see squares), each square is a letter, so just press on a square to get the dictionary.

Here is a good discussion of the basic visual pathway (includes a discussion on crossover) and the central visual pathway (includes pictures of the LGN with parvo and magno pathway locations, a discription of how you get simple cells, etc.) - Washington University School of Medicine Neuroscience Tutorial. Or, try this site by Mather, which is a good overview of the visual cortex (and that great stained visual cortex picture by Tootell et al.)
This site of Human visual cortical areas contains fMRI pictures of V1-V4 in humans. Please note that the pictures A and C are smaller ones on top of B and D.
A very basic outline of the visual pathway in the brain is located here.

Some useful (?) numbers about the visual system.

Some interesting visual problems
Blindsight
Prosopagnosia
Motion-Blindness

Beyond our class, but take a look at some of the work in visual prosthesis by MIVIP

Basic visual functions / Ch 4
More information about Mach Bands can be found at the University of Toronto website. Other related lateral inhibition links can be found at M. Bach's site (where there is a link to my favorite illusion - the scintillating grid).

How television works - you need to understand how the brain breaks down information, how motion perception works, and how color perception occurs.

The Dark Adaptation curve as it relates to pigment regeneration.

A bit about the tongue taste map myth and how it got started.

And you thought S&P wouldn't relate to anything useful to you! Check out this site on beer that demonstrates how taste, smell, temp, vision, etc. can all work together to influence our sense of flavor. Here's a site about apples that does the same thing. And one on how wine glasses can affect your experience as well as another site on wine and temperature (although acid is a taste?). And a quick explanation of why peppers are hot and other neat things about peppers (also look here). Some other foods that you might be sensitive to if you are a supertaster. And how to use dye to determine if you are a supertaster.

Umami (or glutamate) information. History, in foods, FAQs, etc. Here is a bit more from Wine Spectator. BTW, this on-line magazine has a lot of information that shows the linkage between taste and many of the other senses (for example, this one on wine tasting..

Somatosensory System  and Vestibular system/ Ch 12
*Notes on the cutaneous senses (touch, kinesthesis, temp, pain)
