In Search of the Motor Engram: Motor Map Plasticity as a Mechanism for Encoding Motor Experience
The Neuroscientist, 2005Motor skill acquisition occurs through modification and organization of muscle synergies into effective movement sequences. The learning process is reflected neurophysiologically as a reorganization of movement representations within the primary motor cortex, suggesting that the motor map is a motor engram.

Monopolar mapping of motor function differs from the most commonly used method of intraoperative mapping, i.e. bipolar direct electrical stimulation at 50-60Hz (Penfield technique mapping). Most importantly, the monopolar probe emits a radial, homogenous electrical field different to the more focused inter-tip bipolar electrical field.

Cortical maps for motor planning
[Proceedings] 1992 RNNS/IEEE Symposium on Neuroinformatics and Neurocomputers, 1992A distributed computational architecture for the motor planning functions is explored. It combines a paradigm of self-organization (for building robust and coherent maps of the different motor spaces) with relaxation dynamics (for run-time incorporation of task constraints).

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.

The output map of the primate motor cortex
Trends in Neurosciences, 1988Abstract What is ‘represented' in the primate motor cortex? Most approaches have defined the output map of the cortex rather than giving any clear answers as to functional representation. This results in part from the artificial nature of the electrical stimuli used to map the outputs.

Mapping The Human Potential as a Motor
Proceedings of the Human Factors Society Annual Meeting, 1981Approximately 200 articles were reviewed to discover what new techniques are being employed to tap the human muscle power potential to perform work. A near absence of published information was found addressing the problem. Consequently, a discussion is presented touching on the physical properties that must exist for humans to serve as motors.

Motor maps, seizures, and behaviour.
Canadian Journal of Experimental Psychology / Revue canadienne de psychologie expérimentale, 2008Atypically organised motor maps have been described in some people with epilepsy and we have modelled this in rats. Our goal is to more fully understand the mechanisms responsible for seizure-induced functional brain reorganisation and to reverse their effects.

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.

Plasticity of Sensory and Motor Maps in Adult Mammals
Annual Review of Neuroscience, 1991This rev iew addresses questions about t he capacity of sensory and motor maps in the brains of adul t mammals to change as a resul t of alterations in the effectiveness of inputs, the availability of effectors, and d irect damage. The issue of the mutabil ity of maps in adults is important because sensory and motor representations occupy much of the ...
