Attention, Intention, and Priority in the Parietal Lobe

For many years there has been a debate about the role of the parietal lobe in the generation of behavior. Does it generate movement plans (intention) or choose objects in the environment for further processing? To answer this, we focus on the lateral intraparietal area (LIP), an area that has been shown to play independent roles in target selection for saccades and the generation of visual attention. Based on results from a variety of tasks, we propose that LIP acts as a priority map in which objects are represented by activity proportional to their behavioral priority. We present evidence to show that the priority map combines bottom-up inputs like a rapid visual response with an array of top-down signals like a saccade plan. The spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention.

- Dopamine in motivational control: rewarding, aversive, and alerting (2010, background): “…from other notions of salience used in neuroscience, such as incentive salience, which applies only to desirable events (Berridge and Robinson, 1998), and perceptual salience, which applies to motivationally neutral features of a stimulus such its orientation or color (Bisley and Goldberg, 2010).”
- Value-based gain control: divisive normalization in parietal cortex (2011, background): “In addition to responses related to target selection and action value, LIP neurons also show activity associated with the allocation of covert attention, driven by intrinsic visual salience or task relevance (Bisley and Goldberg, 2003, 2010; Oristaglio et al., 2006).”
- Visual search: a retrospective. (2011, background): “These include the parieto-occipital area (PO), the posterior intraparietal area (PIP), the medial intraparietal area (MIP), the lateral intraparietal area (LIP), the ventral intraparietal area (VIP), and the anterior intraparietal area (AIP).”
- Deep Hierarchies in the Primate Visual Cortex: What Can We Learn for Computer Vision? (2013, background): “stimulus [65], which led to the suggestion that LIP contains a salience map of the visual field, that guides attention and decides about saccades to relevant stimuli [11].”
- Distinct Computational Principles Govern Multisensory Integration in Primary Sensory and Association Cortices. (2016, positive): “Collectively, these computational operations enable IPS3–4 to form multisensory spatial priority maps that go functionally beyond traditional unisensory spatial priority maps [35, 36].”
- Perceptions as Hypotheses: Saccades as Experiments (2012, background): “Crucially, the predictions of visual input depend upon posterior beliefs about the direction of gaze, encoded by the state units in the “where” stream (Bisley and Goldberg, 2010).”
