TL;DR: A meta-analysis of functional magnetic resonance imaging data collected in 10 awake monkeys to reveal areas in which activity consistently decreases when task demands shift from passive tasks to externally oriented processing, implying in the monkey a functional equivalent of the human DMN.
Journal ArticleDOI
Mapping the parietal cortex of human and non-human primates

TL;DR: MR responses to a range of visual stimuli indicate that the human IPS contains more functional regions along its anterior-posterior extent than are known in the monkey, and these data support the hypothesis that monkey LIP corresponds to the region of human IPS between DIPSM and POIPS and that a portion of the anterior part of humanIPS is evolutionarily new.
Journal ArticleDOI
Contribution of the Monkey Frontal Eye Field to Covert Visual Attention
TL;DR: Comparison of the present results with a similar experiment conducted in the lateral intraparietal cortex area revealed qualitatively different deficits, suggesting that the two areas may make distinct contributions to selective attention processes.
Journal ArticleDOI
Saccadic target selection deficits after lateral intraparietal area inactivation in monkeys.
TL;DR: One important contribution of LIP to oculomotor behavior is the selection of targets for saccades in the context of competing visual stimuli, which is suggested to reflect either an ispilateral bias in saccadic search strategy or an attentional impairment within the contralateral field.
Journal ArticleDOI
Differential effects of parietal and frontal inactivations on reaction times distributions in a visual search task
TL;DR: It is shown that different search strategies can be used by monkeys to perform visual search, either by processing the visual scene in parallel, or by combining parallel and serial processes, and that LIP and FEF inactivations have very different effects on the RT distributions in the two monkeys.
