Intraparietal sulcus maintains working memory representations of somatosensory categories in an adaptive, context-dependent manner

Lisa Alexandria Velenosi, Yuan-Hao Wu, Timo Torsten Schmidt, Felix Blankenburg, Universitätsbibliothek Der FU Berlin
In the somatosensory modality, category representations have been identified in the premotor cortex (PMC) and the intraparietal sulcus (IPS).  ...  One way to investigate the influence of task demands is with categorization paradigms, wherein either a single stimulus or an associated category is maintained in WM.  ...  Finally, the authors would like to extend their sincere gratitude to Reviewer 1 for significantly improving the quality of the manuscript.  ...

Neural correlates of learning and working memory in the primate posterior parietal cortex

Justin B. Rawley, Christos Constantinidis
2009 Neurobiology of Learning and Memory  
These findings demonstrate the importance of posterior parietal cortex in brain networks mediating working memory and learning.  ...  More recently, involvement of posterior parietal cortex in other cognitive functions such as working memory and task learning has become evident.  ...  Acknowledgements Supported in part by NIH grant EY16773 and the Whitehall Foundation.  ...

The primate working memory networks

2004 Cognitive, Affective, & Behavioral Neuroscience  
In this article, we review the current understanding of the anatomical organization of networks mediating working memory and the neural correlates of memory manifested in each of their nodes.  ...  Anatomical and physiological evidence suggests, however, that the prefrontal cortex is part of a broader network of interconnected brain areas involved in working memory.  ...  Working memory is the term commonly used for the ability to maintain information in memory over a time span of a few seconds.  ...

Somatosensory processes subserving perception and action

H. Chris Dijkerman, Edward H. F. de Haan
2007 Behavioral and Brain Sciences  
We suggest that, analogously to the organisation of the visual system, somatosensory processing for the guidance of action can be dissociated from the processing that leads to perception and memory.  ...  The functions of the somatosensory system are multiple.  ...  work together in the production of adaptive behaviour.  ...

The active construction of the visual world

Thomas Parr, Karl J. Friston
2017 Neuropsychologia  
Analysis of a somatosensory scene depends on what is palpated, in much the same way that visual analysis relies on what is foveated.  ...  This review offers an overview of the neurobiology of visual perception, which begins with the control of saccadic eye movements.  ...  The former appears to be memory dependent, while the latter does not. This hints at the importance of axons in the region of intraparietal sulcus.  ...

Human Visual Understanding for Cognition and Manipulation -- A primer for the roboticist [article]

Martin Hjelm
2019 arXiv   pre-print
Our hope is that the article will provide insights for the robotic researcher that can help them navigate the path of self-examination, give them an overview of current theories about human visual processing  ...  However, given current theories about human cognition and sensory processing, it is reasonable to assume that the internal workings of the brain are separate from how we interface with the world and ourselves  ...  Research has shown that the brain generates different representations of an object depending on which task or context we view it in.  ...

Human, Nature, Dynamism: The Effects of Content and Movement Perception on Brain Activations during the Aesthetic Judgment of Representational Paintings

Cinzia Di Dio, Martina Ardizzi, Davide Massaro, Giuseppe Di Cesare, Gabriella Gilli, Antonella Marchetti, Vittorio Gallese
2016 Frontiers in Human Neuroscience  
The aim of this work was to explore, through functional magnetic imaging (fMRI), how perceived movement is processed during the aesthetic judgment of paintings using two types of content: human subjects  ...  Furthermore, considering the functional roles of posterior and central insula, we suggest that nature paintings may evoke aesthetic processes requiring an additional proprioceptive and sensori-motor component  ...  According to this view, the observer would be engaged by the represented scene, immersed in the portrayed context in an "embodied" manner.  ...

Perturbing the Action Observation Network During Perception and Categorization of Actions' Goals and Grips: State-Dependency and Virtual Lesion TMS Effects

P. O. Jacquet, A. Avenanti
2013 Cerebral Cortex  
Watching others grasping and using objects activates an action observation network (AON), including inferior frontal (IFC), anterior intraparietal (AIP), and somatosensory cortices (S1).  ...  In the Goal-recognition task, IFC and S1 stimulation differently affected the processing of "adapted" and "nonadapted" goals.  ...  Our study expands these prior findings by providing causal evidence that IFC is also critical for processing (and possibly maintaining in working-memory) observed grips.  ...

The origins of metamodality in visual object area LO: Bodily topographical biases and increased functional connectivity to S1

Zohar Tal, Ran Geva, Amir Amedi

Transforming vision into action

Melvyn A. Goodale
2011 Vision Research  
In this review, I examine some of the seminal work on the role of vision in the control of manual prehension and on the visual cues that play a critical role in this important human skill.  ...  Except for the study of eye movements, which have been regarded as an information-seeking adjunct to visual perception, little attention was paid to the way in which vision is used to control our actions  ...  The visual control of reaching engages networks in the medial bank of the intraparietal sulcus (MIP) and in the parieto-occipital sulcus (area V6A).  ...
