A neuronal representation of the location of nearby sounds
Article Abstract:
Sound source location can be accurately perceived by humans, although little is known about the perception of auditory distance. The direction to a sound source is determined by interaural differences, but it is unknown how neurons encode auditory distance information. Neurons in the brain of macaque monkeys, representing the auditory space around the head, are described. Those located in the ventral premotor cortex had spatial receptive fields, extending a short distance out from the head. The results show that ventral premotor cortex (PMv) neurons represent nearby auditory space.

Spatial awareness is a function of the temporal not the posterior parietal lobe
Article Abstract:
It has been established that the superior temporal cortex is the neural substrate of spatial neglect in humans. Spatial neglect in humans is mainly associated with right-hemispheric lesions, while loss of awareness of the contralesional side in monkeys is seen following lesions in this area in the right or left hemisphere.

Awareness of space
Article Abstract:
New research challenges the view that the parietal lobe is the part of the brain responsible for spatial awareness. It was found that damage to the superior temporal lobe seems to be responsible for hemispatial neglect, while parietal damage is the cause of visual-field defects.
