ERP STUDIES OF ATTENTION FOLLOWING PARIETAL DAMAGE

Project: Research project

Project Details

Description

Visual-spatial selective attention is an essential brain function that
enables human observers to select and process relevant information.
The parietal lobes have long been implicated in this function.
Although many studies have contributed significant information about
the behavioral impairments in patients with parietal damage, little is
known about the locus of information processing deficits in these
patients. The experiments described in this proposal will investigate
the role of the parietal lobes in the initial sensory processing of
information as well as attentional modulation and orienting. To this
end, patients with focal lesions will be tested in spatial attention
paradigms. It is hypothesized that attentionaI deficits in these
patients are manifest in part by impairments in the ability to
attentionally modulate sensory information. Event-related potentials
as well as response times will be recorded to index the precise
processing stages during which these impairments occur.
