Neural Mechanisms of Visual Memory: A Neurocomputational Perspective
Gustavo Deco, Edmund T. Rolls · Oxford University Press eBooks · 2008
Studies have shown that the prefrontal cortex (PFC) is involved in at least some types of working memory functions. Neurodynamics helps us understand the underlying mechanisms that implement the working memory-related activity observed in the primate PFC. This chapter reviews the application of these techniques for the analysis of experimental measurements gained at different levels (single-cell, functional magnetic resonance imaging (fMRI)) of the prefrontal and inferior temporal (IT) visual cortex that result in a better understanding of the neural mechanisms of visual memory. It also considers the mechanisms that enable the IT visual cortex to set up view-invariant representations of objects — a process that involves not just storing information in a long-term form of memory, but also building suitable object representations to be stored.
