The answer to this question is:
<span>The
brain structure that is most likely causing this is the
“Reticular Formation”.</span>
<span>
The
reticular formation plays a vital role in states of consciousness like awareness
and sleep. It has connections to the thalamus and cerebral cortex
that allow it to gain some control over which sensory signals arrive at the
cerebrum and come to our conscious attention. </span>
This illustrates "inattentional blindness".
Inattentional blindness which is otherwise called perceptual blindness is a mental absence of consideration that isn't related with any vision deformities or shortages. It might be additionally characterized as the occasion in which an individual neglects to see an unexpected stimulus that is on display. Inattentional blindness basically implies that you miss something directly before you.
