In order to accurately interpret experimental data using the topographic body map identified by conventional intracortical microstimulation (ICMS), it is important to know how neurons in each division of the map respond during voluntary movements. Here we systematically investigated neuronal responses in each body representation of the ICMS map during a reach-grasp-retrieval task that involves ...

introduction: attenuation correction is a useful process for improving myocardial perfusion spect and is dependent on activity and distribution of attenuation coefficients in the body (attenuation map). attenuation artifacts are a common problem in myocardial perfusion spect. the aim of this study was to compare the effect of attenuation correction using different attenuation maps and different...

Synopsis The organization of the motor cortex has been studied and debated for more than 130 years. Although it contains a map of the body, the map is overlapping and fractured and therefore additional principles of organization may be needed to explain the topography. Recently, a growing body of evidence suggests one such principle. The motor cortex appears to be partly organized as a map of c...
