The control of attention - Clinical evidence of brain regions involved in attentional control

6 important questions on The control of attention - Clinical evidence of brain regions involved in attentional control

What is the most common lesion that results in attentional deficits

These deficits arises from damage to the right inferior parietal lobe

What is the general rule of unilateral frontal lesions

They tend to have a greater effect on the more overt aspects of attention, such as the ability to direct eye movement toward the contralateral hemispace

What are the two ideas why a lesion in the right hemisphere is worse (in terms of problems) than the left

  • Attention to the left is mostly done by the right hemisphere where motion to the left is done by both
  • the left hemisphere is specialised for language
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

Bilateral damage to the dorsal posterior parietal and lateral occipital cortex can lead to which disorder?

Balint's syndrome

What is oculomotor apraia

Difficulty voluntarily directing the eye gaze toward objects is the visual field with a saccade

What is the sprague effect

The hemisphere neglect induced by a parietal lesion in humans can be nullified by a lesion of the superior colliculus on the other side, this helps restore the balance
