Thinking in spatial terms: decoupling spatial representation from sensorimotor control in monkey posterior parietal areas 7a and LIP

Matthew V. Chafee, David A. Crowe
2013 Frontiers in Integrative Neuroscience  
In this review, we approach that question in the context of the neural representation of space in posterior parietal cortex of non-human primates.  ...  However, in order to think, the cerebral cortex has to generate patterns of neuronal activity that encode abstract, generalized information independently of ongoing sensorimotor events.  ...  ACKNOWLEDGMENTS The authors are grateful to Apostolos Georgopoulos who provided the intellectual motivation for many of their studies into the neural basis of spatial cognition.  ...

2014 Trends in Augmentation of Human Performance  
Here we review the neural representations of movement plans in the cortex and discuss the potential utility of these representations for jointly performed motor actions, particularly manipulation tasks  ...  It is generally acknowledged that such interactions can be enhanced by providing robots with advance knowledge of the intentions of human agents, e.g. their desired motor plans and goals in a given context  ...  Being association areas of the cortex, neurons in the parietal and premotor regions often exhibit both sensory-and motor-related responses.  ...
