Experiments were made on the posterior parietal association cortical areas 5 and in 17 hemispheres of 11 monkeys, 6 M. mulatta and 5 M. arctoides. The electrical signs of the activity of single cortical cells were recorded with microelectrodes in waking animals as they carried out certain behavioral acts in response to a series of sensory cues. The behavioral paradigms were one for detection alone, and a second for detection plus projection of the arm to contact a stationary or moving target… 

Functional properties of parietal visual neurons: mechanisms of directionality along a single axis

The directional properties of parietal visual neurons (PVNs) were examined using the method of single-neuron analysis in waking monkeys using conditioning-test paradigms and revealed a feed-forward inhibition preceding a stimulus.

Unit activity in monkey parietal cortex related to haptic perception and temporary memory

Relatively little evidence was found to support a functional distinction between the neural response properties of areas 2 and 5 a, which suggests that area 2 may be at a higher level in the somatosensory heirarchy of the posterior parietal cortex than usually considered.

Posterior parietal cortex: functional properties of neurons in area 5 during an instructed-delay reaching task within different parts of space

Under experimental conditions, cell activity in area 5 changed so that the population of preferred direction vectors of parietal neurons rotated in space in a way which predicted the rotation of the arm necessary to perform the task.

Functional properties of neurons in the temporo-parietal association cortex of awake monkey

The present results suggest that the temporo-parietal association cortex studied participates in the analysis of the temporal pattern of a sound, the location of the sound source and in spatial control of head movements.

The Parietal Visual System and some Aspects of Visuospatial Perception

For the functional properties of the several major classes of neurons identified in the posterior parietal homotypical cortex of the monkey mimic many of the functions attributed to the parietal system in man, and mirror the defects seen in man and other primates after parietal lobe lesions.

Four new directions of research that are presently being explored from this foundation are reviewed in this article, including a previously unexplored area within the intraparietal sulcus has been found whose cells hold a representation in memory of planned eye movements.

Activity of neurons in area 6 of the cat during fixation and eye movements

Based on the paucity of pre-saccadic neurons, it would be difficult to conclude that this region of cortex in the cat is homologous to the frontal eye fields of the monkey, but when considered in the context of differences in the oculomotor habits of these two animals, it is believed the homology fits.

Modality and topographic properties of single neurons of cat's somatic sensory cortex.

Observations upon the modality and topographical attributes of single neurons of the first somatic sensory area of the cat’s cerebral cortex, the analogue of the cortex of the postcentral gyrus in the primate brain, support an hypothesis of the functional organization of this cortical area.
