Year: 1999 | Volume: 18, Issue: 3 | Magazine Article |

Cited by: Papers (21)

Patients with frontal-lobe epilepsy comprise the second largest group undergoing epilepsy surgery. It has been reported that the difficulty in localizing the epileptogenic zone in these patients is due to the rapid spread of the epileptiform activity within the frontal lobe and to adjoining regions of the brain. We formulated the question of whether the functional localization of dynamic sources o...Show More

Although the content of working memory (WM) can be decoded from the spatial patterns of brain activity in early visual cortex, how populations encode WM representations remains unclear. Here, we address this limitation by using a model-based approach that reconstructs the feature encoded by population activity measured with fMRI. Using this approach, we could successfully reconstruct the locations...Show More

A functional approach to brain processing is introduced associated with control models, in which 'observer' models of effectors and other parts of the external world are used for improved processing. These models are briefly applied to higher cognitive processes (working memory and attention) using the presence of a monitor system, so as to lead to a general framework for analysing brain function.Show More
