Investigating Neuronal Cell Classes and their Role in Cognition
… features were distinguished in area 7A, the lateral intraparietal area (LIP), the dorsolateral and ventrolateral prefrontal cortex (PFC) and the extrastriate visual area (V4). While the number of cell classes found across areas differed, there were several classes across areas that appeared …

Competition between visual stimuli in the monkey parietal cortex
… and reliability of neural signals. The macaque lateral intraparietal area (LIP) is part of an oculomotor attentional network and its activity represents the relative priority of spatial locations. We demonstrate how neurons in LIP use surround suppressive mechanisms to resolve conflict between …

Decision-making in the primate brain : formation, location, and causal manipulation
… neuroscience: that neurons in the monkey lateral intraparietal (LIP) cortex accumulate sensory information in favor of a decision communicated by an eye-movement. I found that despite strong correlations between LIP responses and decisions, reversible inactivation of neurons in LIP had no …

The influences of preparation and brain states on the time-course of oculomotor control in visual selection
… parietal regions, with sources located in the lateral intraparietal area. The source of alpha activity for the errors occurring in the slow responses was instead located more in the frontal lobes and specifically around the dorsolateral prefrontal cortex.

Spiking and oscillatory correlates of visual short-term memory for multiple items
… 2, we examine local field potentials in the lateral intraparietal area (LIP), frontal eye field, and lateral prefrontal cortex (PFC). At stimulus encoding, lower frequency oscillations decreased in power in proportion to the total number of stimuli presented, while higher frequency …

Comparison of frontal and parietal cortices in the control of visual attention
… from both parietal cortex (specifically, the lateral intraparietal cortex) and prefrontal cortex (specifically, the frontal eye fields and dorsolateral prefrontal cortex). We address four main questions. First, we contrast the respective roles of frontal and parietal cortex in the direction of …

Neuroethology of Social Attention in Primates
… area implicated in attention control--the lateral intraparietal area, LIP. Our findings suggest that gaze-following abilities may be widespread in social primates, relying on conserved, homologous brain pathways; and that they may not be informationally-encapsulated reflexes, but rather are …

Processing of quantitative information, investigated with fMRI.
… by use of single-cell recording, in the lateral intraparietal area (LIP) of the macaque monkey. In this thesis, we searched for evidence of number-sensitive coding in humans. Using a priming paradigm, we found behavioural evidence for a number-sensitive system in humans for small …

Multisensory Integration in adults with Attention-Deficit/Hyperactivity Disorder
… are located in the posterior parietal cortex, lateral intraparietal, and superior temporal sulcus. Depending on the task demands and the complexity of the MI-stimuli, the attentional resources that are allocated are varying. While, salient, relative simply multimodal stimuli are integrated …
