Two different areas within the primary motor cortex of man
THE primary motor area (M1) of mammals has long been considered to be structurally and functionally homogeneous1–5. This area corresponds to Brodmann's cytoarchitectural area 4. A few reports showing… Expand
Estimation of the Probabilities of 3D Clusters in Functional Brain Images
The interpretation of functional brain images is often hampered by the presence of noise. This problem is most commonly solved by using a statistical method and only considering signals that are… Expand

Supplementary motor area and other cortical areas in organization of voluntary movements in man.
1. Previous studies in man have revealed a coupling between the regional cerebral blood flow (rCBF) and the regional cerebral metabolic rate for oxygen. In normal man, increases in the regional… Expand
Neural correlates of dual task interference can be dissociated from those of divided attention: an fMRI study.
When people perform two tasks simultaneously, the tasks are often executed slower and with more errors than when they are carried out as single tasks. This is called dual task interference. With… Expand
Illusory Arm Movements Activate Cortical Motor Areas: A Positron Emission Tomography Study
Vibration at ∼70 Hz on the biceps tendon elicits a vivid illusory arm extension. Nobody has examined which areas in the brain are activated when subjects perceive this kinesthetic illusion. The… Expand
Does mental activity change the oxidative metabolism of the brain?
Previous studies have shown that sensory stimulation and voluntary motor activity increase regional cerebral glucose consumption and regional cerebral blood flow (rCBF). The present study had 3… Expand
Shape and roughness activate different somatosensory areas in the human brain.
Somatosensory stimuli are known to activate the postcentral gyrus, and neurons there fire when the skin is in contact with objects. Also neurons in the lateral fissure, the parietal operculum, fire… Expand
Functions and structures of the motor cortices in humans
Humans and non-human primates have several motor areas. Exactly how many is a matter of current debate. A proper parcellation of motor areas must be based on correlated structural and functional… Expand
Activation by Attention of the Human Reticular Formation and Thalamic Intralaminar Nuclei
It has been known for over 45 years that electrical stimulation of the midbrain reticular formation and of the thalamic intralaminar nuclei of the brain alerts animals. However, lesions of these… Expand
