The recorded neuromagnetic oscillatory activity of the human primary motor cortex is activated during observation as well as execution of motor tasks, which has implications for a better understanding of the machinery underlying action recognition in humans.

It is suggested that the motor cortex drives the spinal motoneuronal pool during sustained contractions, with the observed cortical rhythmic activity influencing the timing of efferent commands.

It is concluded that the fusiform gyrus may selectively encode faces at 165 ms, transforming sensory input for further processing, and may use these features in constructing its face-specific response.
Removal of magnetoencephalographic artifacts with temporal signal‐space separation: Demonstration with single‐trial auditory‐evoked responses
The results demonstrate that tSSS is a robust and efficient method for removing a wide range of different types of interference signals in neuromagnetic multichannel measurements.

Multichannel neuromagnetic recordings were used to differentiate signals from the human first (SI) and second (SII) somatosensory cortices and to define representations of body surface in them. The…
The compassionate brain: humans detect intensity of pain from another's face.

Using functional magnetic resonance imaging, it is shown that not only the presence of pain but also the intensity of the observed pain is encoded in the observer's brain-as occurs during the observer’s own pain experience.
