Two different areas within the primary motor cortex of man
TLDR
It is shown that area 4 in man can be subdivided into areas '4 anterior' and '4 posterior' (4p) on the basis of both quantitative cytoarchitecture and quantitative distributions of transmitter-binding sites and by positron emission tomography that two representations of the fingers exist.

Estimation of the Probabilities of 3D Clusters in Functional Brain Images
TLDR
A modification of the cluster analysis proposed by Roland et al. is presented, showing the method used to be specific and sensitive and is further compared with SPM96 and the nonparametric method of Holmes etAl.
Supplementary motor area and other cortical areas in organization of voluntary movements in man.
TLDR
It is suggested that the supplementary motor areas are programming areas for motor subroutines and that these areas form a queue of time-ordered motor commands before voluntary movement are executed by way of the primary motor area.
Asymmetry in the Human Motor Cortex and Handedness
TLDR
Using magnetic resonance morphometry, it is shown for the first time that the depth of the central sulcus is related to handedness.
Neural correlates of dual task interference can be dissociated from those of divided attention: an fMRI study.
TLDR
FMRI shows that concurrently performed visual and somatosensory reaction time (RT) tasks engage almost identical volumes of cortical and subcortical motor structures, but dual RT tasks engaged additional cortical regions that are not activated by the component RT tasks had they been performed as single tasks.
Illusory Arm Movements Activate Cortical Motor Areas: A Positron Emission Tomography Study
TLDR
Against the authors' expectations, motor areas rather than somatosensory areas seem to convey the illusion of limb movement.
Functions and structures of the motor cortices in humans
Shape and roughness activate different somatosensory areas in the human brain.
TLDR
These findings demonstrate a separation in functional contributions of lateral parietal opercular cortex and IPA, and indicate different cortical processing streams for the somatosensory submodalities microgeometry and macrogeometry.
