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 areExpand

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 regionalExpand

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. TheExpand

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 3Expand

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, fireExpand

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 functionalExpand

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 theseExpand

Hierarchical Processing of Tactile Shape in the Human Brain
It is not known exactly which cortical areas compute somatosensory representations of shape. This was investigated using positron emission tomography and cytoarchitectonic mapping. VolunteersExpand

Vibratory stimulation increases and decreases the regional cerebral blood flow and oxidative metabolism: a positron emission tomography (PET) study
The aim of this study was to examine the hypothesis, if the activation of some cerebral structures due to physiological stimulation is accompanied by deactivations of other structures elsewhere inExpand

Brain atlases - a new research tool
TLDR
Conventional brain atlases are collections of micrographs or schematic drawings of brain sections from one or a few brains in which anatomical structures are identified, for example, nuclei, cortical areas and fibre tracts. Expand
