Selective and divided attention during visual discriminations of shape, color, and speed: functional anatomy by positron emission tomography

Department of Neurology and Neurological Surgery, Washington University School of Medicine, St. Louis, Missouri 63110.
Positron emission tomography (PET) was used to identify the neural systems
involved in discriminating the shape, color, and speed of a visual stimulus
under conditions of selective and divided attention. Psychophysical
evidence indicated that the sensitivity for discriminating subtle stimulus
changes in a same-different matching task was higher when subjects
selectively attended to one attribute than when they divided attention
among the attributes. PET measurements of brain activity indicated that
modulations of extrastriate visual activity were primarily produced by task
conditions of selective attention. Attention to speed activated a region in
the left inferior parietal lobule. Attention to color activated a region in
the collateral sulcus and dorsolateral occipital cortex, while attention to
shape activated collateral sulcus (similarly to color), fusiform and
parahippocampal gyri, and temporal cortex along the superior temporal
sulcus. Outside the visual system, selective and divided attention
activated nonoverlapping sets of brain regions. Selective conditions
activated globus pallidus, caudate nucleus, lateral orbitofrontal cortex,
posterior thalamus/colliculus, and insular-premotor regions, while the
divided condition activated the anterior cingulate and dorsolateral
prefrontal cortex. The results in the visual system demonstrate that
selective attention to different features modulates activity in distinct
regions of extrastriate cortex that appear to be specialized for processing
the selected feature. The disjoint pattern of activations in extravisual
brain regions during selective- and divided-attention conditions also
suggests that preceptual judgements involve different neural systems,
depending on attentional strategies.
