Unilateral neglect restricted to visual imagery

Article Abstract:

A patient with a lesion in the right frontal lobe demonstrated a disorder in visual imagery but no neglect for actual stimuli, in contrast to previous studies that have consistently linked the two disorders. The lesion's location suggests that the frontal lobe plays a specific role in some types of mental imagery but not of spatial perception. The disorders usually are linked to damage to the parieto or temporo-occipital cortex.

Modulation by instruction

Article Abstract:

Positron emission tomography (PET) studies performed by Wayne C. Drevets and colleagues reveals that local neuronal activity in the brain associated with memory is influenced by the blood flow in the brain. The PET enables the accurate measurement of blood flow in the brain. The PET studies reveal that there is a modulation of blood flow during voluntary concentration of the senses.
