Getting a Grasp on Coordination

P. Weiss, M. Jeannerod
1998 Physiology  
One subset of theories defined the limb posture at the end of the movement as the controlled variable, whereas others concentrated on the trajectory of the endpoint of the limb as the optimized parameter  ...  However, promising new concepts postulate that many different, especially cortical, structures are recruited in a neural network subserving motor coordination depending on the goal of the action.  ...  The Ca 2+ mobilization occurs during neurogenesis and diminishes in parallel with the declining of mitotic activities of the neuroepithelial cells.  ...

The Dorsomedial Pathway Is Not Just for Reaching: Grasping Neurons in the Medial Parieto-Occipital Cortex of the Macaque Monkey

P. Fattori, V. Raos, R. Breveglieri, A. Bosco, N. Marzocchi, C. Galletti
2010 Journal of Neuroscience  
Brain control of prehension is thought to rely on two specific brain circuits: a dorsomedial one (involving the areas of the superior parietal lobule and the dorsal premotor cortex) involved in the transport  ...  of the hand toward the object and a dorsolateral one (involving the inferior parietal lobule and the ventral premotor cortex) dealing with the preshaping of the hand according to the features of the object  ...  dorsomedial circuit may support motor planning for prehension on the basis of advance visual information (Grol et al., 2007; Verhagen et al., 2008) .  ...

Evidence for a distributed hierarchy of action representation in the brain

Scott T. Grafton, Antonia F. de C. Hamilton
2007 Human Movement Science  
The retrieval errors in apraxia also support the notion of a hierarchical model for representing action in the brain.  ...  Behavioral studies based on tasks such as normal prehension, multi-step object use and imitation establish the existence of relative hierarchies of motor control.  ...  Acknowledgement Supported by PHS grants NS 33504, NS 44393 and the James S. McDonnell Foundation.  ...

Broca's Area in Language, Action, and Music

Luciano Fadiga, Laila Craighero, Alessandro D'Ausilio
2009 Annals of the New York Academy of Sciences  
Recently, the critical involvement of the same areas in representing abstract hierarchical structures has also been demonstrated.  ...  Although most of his claims are still true today, the emergence of novel techniques as well as the use of comparative analyses prompts modern research for a revision of the role played by Broca's area.  ...  Conflicts of Interest The authors declare no conflicts of interest.  ...

Toward a computational framework for cognitive biology: Unifying approaches from cognitive neuroscience and comparative cognition

W. Tecumseh Fitch
2014 Physics of Life Reviews  
Finally, I review the role of the theory of computation and formal language theory in the recent explosion of comparative biological research attempting to isolate and explore how different species differ  ...  Starting at the neuronal level, I first discuss the contemporary realization that single neurons are powerful tree-shaped computers, which implies a reorientation of computational models of learning and  ...  Acknowledgements I acknowledge the financial support of ERC Advanced Grant SOMACCA, and thank Daniel Bowling and an anonymous reviewer for detailed comments on an earlier version of the manuscript.  ...

Probabilistic language models in cognitive neuroscience: promises and pitfalls [article]

Kristijan Armeni, Roel M. Willems, Stefan Frank
2017 bioRxiv   pre-print
Measures obtained from these models emphasize the probabilistic, information-processing view of language understanding and provide a set of tools that can be used for testing neural hypotheses about language  ...  On the cognitive part of the equation, it is important that the computations and processing complexity are explicitly defined.  ...  Acknowledgments The work presented here was partly funded by the Netherlands Organisation for Scientific Research (NWO) Gravitation Grant 024.001.006 to the Language in Interaction Consortium and Vidi  ...

Cross-modal and scale-free action representations through enaction

Alex Pitti, Hassan Alirezaei, Yasuo Kuniyoshi
2009 Neural Networks  
We present a biologically plausible mechanism to the representation and the recognition of actions in a neural network with spiking neurons based on the learning mechanism of spike-timing-dependent plasticity  ...  The network evolves into a small-world organization with scale-free dynamics promoting efficient inter-modal binding of the neural assemblies with accurate timing.  ...  Acknowledgment The authors would like to acknowledge the Asada ERATO Synergistic project which provided the grant for this research.  ...

The Evolution of Cognitive Control

Dietrich Stout
2010 Topics in Cognitive Science  
One of the key challenges confronting cognitive science is to discover natural categories of cognitive function. Of special interest is the unity or diversity of cognitive control mechanisms.  ...  The archeological record further indicates the timing and context of distinctively human elaborations to these cognitive control functions, including the gradual emergence of increasingly complex hierarchical  ...  Acknowledgments This work was supported in part by the Commission of the European Communities Research Directorate-General Specific Targeted Project number 029065, ''Hand to Mouth: A framework for understanding  ...
