dc.description.abstract | Only a small fraction of all the information reaching our senses can be the object of conscious report
or voluntary action. Although some models propose that different attentional states (top-down
amplification and vigilance) are necessary for conscious perception, few studies have explored how the
brain activations associated with different attentional systems (such as top-down orienting and phasic
alerting) lead to conscious perception of subsequent visual stimulation. The aim of the present study
was to investigate the neural mechanisms associated with endogenous spatial attention and phasic
alertness, and their interaction with the conscious perception of near-threshold stimuli. The only region
demonstrating a neural interaction between endogenous attention and conscious perception was the
thalamus, while a larger network of cortical and subcortical brain activations, typically associated with
phasic alerting, was highly correlated with participants’ conscious reports. Activation of the anterior
cingulate cortex, supplementary motor area, frontal eye fields, thalamus, and caudate nucleus was
related to perceptual consciousness. These data suggest that not all attentional systems are equally
effective in enhancing conscious perception, highlighting the importance of thalamo-cortical circuits on
the interactions between alerting and consciousness. | es |
