Most of the readings are available online by following the links provided below. Others are available in the filing cabinet in Room 808 (under the long table). Please make copies and return the originals to the appropriate file folder for future generations.
Some of the readings are labelled (above) as being "secondary readings". By this, I mean that you should skim through each of these papers to see what's there, read the abstract & intro, look at the figures and figure captions. This is the same as what you should do when exploring the literature in your area of research. Then, based on your interests and what you feel you need to know, you can pick and choose which of these "secondar readings" to read in more detail. For some topics, there are quite a few papers assigned. Unfortunately, there is no single review paper that covers all of the relevant material. But at the same time, we do not expect you to read every word of it. Because of the overwhelming amount of scientific literature in every subarea of neuroscience, you need to develop a skill for rapidly scanning the literature to get the basics, and then be able to go back as needed to get the details.

How does synaptic inhibition contribute to the spatial selectivity of visual neurons in the retina and primary visual cortex?
Describe what is meant by the functional specialization hypothesis and summarize the evidence both for and against it in visual cortex. Specifically, address the following questions:
a) Explain the factors that are used to define a functional specialized visual cortical areas?
b) Area MT (in both humans and monkeys) is perhaps the best example of a functionally specialized brain area. Summarize some of the key experimental techniques in both humans and monkeys that have been used to define MT as a distinct brain area that is functionally specialized for visual motion perception.
c) Even in MT, our best example of functional specialization, there compelling reasons to remain cautious in drawing conclusions about the area's function. Describe some such reasons.
Adaptation is a ubiquitous property of sensory systems. In the somatosensory system adaptation plays an important role in defining the properties and the functional attributes of light touch submodalities.
a) For TWO light touch submodalities show what role adaptation plays in shaping their properties. [In this part consider the role of adaptation at the receptor and how it shapes the temporal characteristics of the response]
b) Can you make a link between neural adaptation and touch perception in each of the parallel pathways you have chosen? Use examples to illustrate the linking hypothesis.
c) Design a psychophysical experiment in human subjects where you would use adaptation as a tool to investigate the properties of “channels” in the somatosensory system. Outline what experiments you would do and what results you might expect. How would you use the outcome of your experiments to test hypotheses about the “channels” in the somatosensory pathway? [In this section think of adaptation in the sense that it reduces the sensitivity or efficacy of the pathway and hence you use it to probe whether there are “channels”]
