Clinical Motor Mapping with Magnetoencephalography
2020This chapter examines clinical motor mapping with magnetoencephalography (MEG). Motor cortex functional mapping procedures were first conducted by neurosurgeons who famously stimulated their patient’s exposed brain during surgery and then systematically documented the responses observed from the activated muscles of the body.

Computing the motor-sensor map
Behavioral and Brain Sciences, 2004“Articulate models” subservient to formal intelligence are imagined to be heterarchies of automata capable of performing the “symbolic (quasi-spatial) syntheses” of Luria (1973), where “quasi-spatial” points to the abstract core of spatiality: the symbol productions, combinations, and substitutions of algebraic reckoning.

TMS Orientation for NIRS-Functional Motor Mapping
Brain Topography, 2006Functional near-infrared spectroscopic imaging (NIRS imaging) has the potential to elucidate the relationship between neuronal activity and oxygenation responses. However, its signal specificity to the functional cortex is sometimes spoiled by its rough spatial resolution.

Mapping motor representations with positron emission tomography
Nature, 1994Brain activity was mapped in normal subjects during passive observation of the movements of an 'alien' hand and while imagining grasping objects with their own hand. None of the tasks required actual movement. Shifting from one mental task to the other greatly changed the pattern of brain activation. During observation of hand movements, activation was

Motor point map of upper body muscles
European Journal of Applied Physiology, 2014The purpose of the present study was to systematically investigate the upper body motor point (MP) positions of selected muscles and to create an atlas of the identified MPs.MPs were searched bilaterally in 15 male and 15 female subjects by scanning the skin with a special pen electrode at low stimulation frequency (3 Hz) and current amplitude (

Microtubule motors and other maps
Proceedings, annual meeting, Electron Microscopy Society of America, 1990Microtubules are involved in a number of forms of intracellular motility, including mitosis and bidirectional organelle transport. Purified microtubules from brain and other sources contain tubulin and a diversity of microtubule associated proteins (MAPs).

Interaction of kinesin motors, microtubules, and MAPs
Journal of Muscle Research and Cell Motility, 2005Kinesins are a family of microtubule-dependent motor proteins that carry cargoes such as vesicles, organelles, or protein complexes along microtubules. Here we summarize structural studies of the "conventional" motor protein kinesin-1 and its interactions with microtubules, as determined by X-ray crystallography and cryo-electron microscopy.

Motor Maps for Nonlinear Control
AIP Conference Proceedings, 2002In this paper the design of a motor map to control a chaotic system is presented. A feedback entrainment scheme is adopted: a system with different parameters is used to generate the reference trajectory for the chaotic system to be controlled, while the motor map provides the appropriate gain value of the feedback signal. As input of the motor map the

Dynamic features of sensory and motor maps
Current Opinion in Neurobiology, 1992Recent data support the idea that the functional organizations of sensory and motor maps in the mature brain are dynamically maintained. Experiments employing peripheral injuries or other manipulations indicate that these maps are capable of extensive reorganization.
