Cognitive Neuroscience and the Human Self

Abstract: Cognitive neuroscience is the branch of neuroscience that focuses on questions about how memory, perception, reasoning, and so on, arise from the operation of neural circuits. Cognitive neuroscience would contribute to issues about knowledge and values if it could explicate ways in which the structure of the brain constrains what and how we can know. In this chapter I describe how the self can be conceptualized within this approach. I argue that cognitive neuroscience provides a framework for conceptualizing what we mean when we speak of the self, and what would be necessary for the self to change.

A Cognitive Neuroscience of Alzheimer’s Disease: What Can Be Learned from Studies of visual Imagery?

Abstract: Complex cognitive abilities are subserved by sets of component subsystems working together. Behavioral deficits, such as those that occur in Alzheimer’s disease, arise when subsystems malfunction or interact improperly. A theory of component subsystems of visual mental imagery is described, which specifies five major sets of components; these components are hypothesized to be implemented in different regions of the brain. The theory is used to guide investigations of the effects of normal aging on different aspects of imagery, and the results of these studies suggest that normal aging selectively affects aspects of imagery that depend on frontal lobe function. These findings are used to formulate hypotheses about possible relations between Alzheimer’s disease, normal aging, and visual mental imagery.
