The data do not suggest left hemisphere superiority in the facilitating effects of action observation on the motor system, but they support the notion of a sensory-motor loop according to which sensory stimulus properties directly affect motor cortex activity, even when no motor output is required.
A large, open source dataset of stroke anatomical brain images and manual lesion segmentations
This work presents ATLAS (Anatomical Tracings of Lesions After Stroke), an open-source dataset of 304 T1-weighted MRIs with manually segmented lesions and metadata that can be used to train and test lesion segmentation algorithms and provides a standardized dataset for comparing the performance of different segmentation methods.

The data indicate that visual and motor components of the human mirror system are not left-lateralized, and the left hemisphere superiority for language must be have been favored by other types of language precursors, perhaps auditory or multimodal action representations.

Sounds associated with bimanual actions produced greater motor corticospinal excitability than sounds associated with leg movements or control sounds, consistent with the hypothesis that action coding may be a precursor of language.

Seeing one's own face activated regions in the inferior frontal gyrus, inferior parietal lobe and inferior occipital cortex in the right hemisphere and listening to one's voice showed increased activity in theright IFG, suggesting that the right IFG is concerned with processing self-related stimuli across multiple sensory modalities and that it may contribute to an abstract self-representation.
“Aha!”: The neural correlates of verbal insight solutions
Data indicate that verbal insight solutions activate a distributed neural network that includes bilateral activation in the insula, the right prefrontal cortex, and the anterior cingulate, which may play a role in evaluation and metacognition of insight solutions.

The results demonstrate that even in a task that is specialized to the right hemisphere, robust parallel activity in the left hemisphere supports creative processing and support the notion that higher motor planning may be a general component of creative improvisation.
Familiarity modulates mirror neuron and mentalizing regions during intention understanding
It is found that observing all gestures compared to observing still images was associated with increased activity in key regions of both the pMNS and mentalizing systems, a finding that is contrary to prior literature and demonstrates the powerful modulatory effects of both motor and perceptual familiarity on pM NS andmentalizing regions when asked to infer the intentions of intransitive gestures.
