Intrathalamic mechanisms of visual attention.
The classical model of visual processing emphasizes the lateral geniculate nucleus (LGN) as the major intermediary between the retina and visual cortex. Yet, anatomical findings inspired Francis Crick to suggest an alternative model in which the thalamic reticular nucleus, which envelops the LGN, acts as the "guardian" of visual cortex by modulating LGN activity. Recent work by McAlonan and col...
متن کاملPeripheral blood lymphocytes are able to maintain their viability and basic function in normal urine
Background: Similar to inflammatory cells, peripheral blood mononuclear cells (PBMCs) can also infiltrate in to kidney and urinary tracts and subsequently excreted by urine. In this study we determined the viability rate and response to phytohemagglutinin-A (PHA) of human PBMCs in normal urine. Methods: A number of 1×106 ficoll-hypaque isolated PBMCs were dispensed in 1 ml normal urine...
متن کاملThe comparision of upper cross syndrome in children with visual and hearing impairments with normal counterparts
The upper cross syndrome is a postural abnormality with excessive activity of the muscles on the chest and upper trapezius muscles. In this study, upper cross syndrome in hearing impairment, vision impairment, and normal students is investigated. This descriptive- analytic study was performed on 30 poor vision boys, 30 poor hearing boys and 30 normal boys with mean age 11.76±2.89 years and the...
متن کاملNeural mechanisms of selective visual attention.
Selective visual attention describes the tendency of visual processing to be confined largely to stimuli that are relevant to behavior. It is among the most fundamental of cognitive functions, particularly in humans and other primates for whom vision is the dominant sense. We review recent progress in identifying the neural mechanisms of selective visual attention. We discuss evidence from stud...
متن کاملNeural mechanisms of visual selective attention.
Visual selective attention improves our perception and performance by modifying sensory inputs at an early stage of processing. Spatial attention produces the most consistent early modulations of visual processing, which can be observed when attention is voluntarily allocated to locations. These effects of spatial attention are similar when attention is cued in a trial-by-trial, or sustained, f...
