TL;DR: The results suggest diminished neuronal firing or decreased dendritic synaptic density with age, as well as a strict coupling between CMRO2 and CBF, and between CBF and CBV was found, while OER was constant and independent ofCBF andCMRO2.

TL;DR: For example, this paper found that grasp observation significantly activates the cortex of the middle temporal gyrus including that of the adjacent superior temporal sulcus and the caudal part of the left inferior frontal gyrus.

TL;DR: The results showed that listening to action-related sentences activates a left fronto-parieto-temporal network that includes the pars opercularis of the inferior frontal gyrus (Broca's area), as well as the inferior parietal lobule, the intraparietal sulcus, and the posterior middle temporal gyrus.

TL;DR: Brain activity was mapped in normal subjects during passive obser-vation of the movements of an 'alien' hand and while imagining grasping objects with their own hand to support the notion that motor learning during observation of movements and mental practice involves rehearsal of neural pathways related to cognitive stages of motor control.

TL;DR: The pattern of brain activation during observation of actions is dependent both on the nature of the required executive processing and the type of the extrinsic properties of the action presented.
