TL;DR
Functional magnetic resonance imaging is used to examine the attentional modulation of neural activity in the human homolog of the MT-MST complex, which is known to be involved in the processing of visual motion.
Abstract
How does voluntary attention to one attribute of a visual stimulus affect the neural processing of that stimulus? We used functional magnetic resonance imaging to examine the attentional modulation of neural activity in the human homolog of the MT-MST complex, which is known to be involved in the processing of visual motion. Using a visual stimulus containing both moving and stationary dots, we found significantly more MT-MST activation when subjects attended to the moving dots than when they attended to the stationary dots, even though the visual stimulus was identical during the two conditions.

PET is used to demonstrate directly the specialization of function in the normal human visual cortex, and provides direct evidence to show that, just as in the macaque monkey, different areas of the human prestriate visual cortex are specialized for different attributes of vision.

It is reported that the responses of direction-selective neurons in monkey visual cortex are greatly influenced by attention, and that this modulation occurs as early in the cortical hierarchy as the level of the middle temporal visual area (MT).

Perception & PsychophysicsPerceptual load as a major determinant of the locus of selection in visual attention
860 Citations1994Nilli Lavie, Yehoshua Tsal
A literature review supports the conclusion that a clear physical distinction between relevant and irrelevant information is not sufficient to prevent irrelevant processing; early selection also requires that the perceptual load of the task be sufficiently high to exceed the upper limit of available attentional resources.

It was found that judging the relative location of 2 contours was more difficult when they belonged to 2 objects rather than 1, consistent with object-based views of attention and with a hierarchical scheme for position coding, whereby object parts are located relative to the position of their parent object.

The advantage of integrated over separate presentation suggests that a “filtering cost” is incurred when two distinct perceptual objects compete for attention in filtering tasks.
