The cortical mechanisms of grasping have been extensively studied in macaques and humans; here, we investigated whether common marmosets could rely on similar mechanisms despite strong differences in hand morphology and grip diversity. We recorded electrocorticographic activity over the sensorimotor cortex of two common marmosets during the execution of different grip types, which allowed us to study cortical activity (power spectrum) and physiologically inferred connectivity (phase‐slope index… 
Oscillatory Activity in Mouse Lemur Primary Motor Cortex During Natural Locomotor Behavior
TLDR
Investigation of possible neuronal correlates of cortical activity to substrate orientation in an ancestral primate model, the gray mouse lemur, confirms that specific cortical mechanisms are solicited during arboreal locomotion, whereby mouse lemurs adjust cortical activityto substrate orientation during static posture and locomotion and modulate this activity throughout locomotor cycles.
Prehensile kinematics of the marmoset monkey: Implications for the evolution of visually‐guided behaviors
TLDR
The marmoset monkey represents a previously understudied position in the evolution of primate reach and grasp behavior and offers a unique composition of ancestral primate corticospinal organization combined with skilled hand use to explore the evolution and development of visually‐guided actions.
Spectral Power in Marmoset Frontal Motor Cortex during Natural Locomotor Behavior
TLDR
Modulation of γ ERS by substrate orientation (horizontal/vertical) and epoch (preparation/execution) suggests close tuning to movement dynamics and biomechanical demands.
Chronic recordings from the marmoset motor cortex reveals modulation of neural firing and local field potentials overlap with macaques
TLDR
Results demonstrate that marmosets are a robust bridge species for behavioral neuroscience studies with motor cortical electrophysiological signals recorded from microelectrode arrays that are similar to Old World NHPs.
Anterior Intraparietal Area: A Hub in the Observed Manipulative Action Network
TLDR
It is suggested that pAIP constitutes a parietal hub for routing information about OMA identity to the other nodes of the network, suggesting that temporal and prefrontal areas may provide visual and contextual information relevant for manipulative action processing.
Common properties of visually-guided saccadic behavior and bottom-up attention in marmoset, macaque, and human
TLDR
It is found that all species exhibit qualitatively similar saccadic behavior and bottom-up saliency albeit with small differences, and the marmoset is an appropriate model animal to study neural mechanisms for active vision and attention.
Whole brain mapping of somatosensory responses in awake marmosets investigated with ultra-high field fMRI
TLDR
The results show the first whole brain mapping of somatosensory responses acquired in a non-invasive way in awake marmosets and reveal the existence of a body representation organization within the thalamus and the cingulate cortex by computing functional connectivity maps from seeds defined in SI/SII using resting-state fMRI data.
Whole brain mapping of somatosensory responses in awake marmosets investigated with ultra-high field fMRI.
TLDR
The results show the first whole brain mapping of somatosensory responses acquired in a non-invasive way in awake marmosets and find a somatotopic body representation in the thalamus and, for the first time, in the putamen.

Selectivity for grip type and action goal in macaque inferior parietal and ventral premotor grasping neurons.
TLDR
Findings suggest that, in the parieto-frontal system, grip types and action goals are processed by both parallel and converging pathways, and area PFG appears to be particularly relevant for integrating this information for action organization.
Modulations of EEG Beta Power during Planning and Execution of Grasping Movements
TLDR
Analysis of beta oscillations recorded with electroencephalography in a precued grasping task in which two critical parameters were manipulated, observed an increase in beta power around the cue onset followed by a decrease during movement preparation and execution and a transient power increase during object hold.
Selective modulation of interactions between ventral premotor cortex and primary motor cortex during precision grasping in humans
TLDR
The finding that, in humans, PMv–M1 interactions are selectively modulated during specific types of grasp provides further evidence that these connections play an important role in control of the hand.
Parallel Evolution of Cortical Areas Involved in Skilled Hand Use
TLDR
The similarity of these fields in cebus monkeys and distantly related macaque monkeys with similar manual abilities indicates that the range of cortical organizations that can emerge in primates is constrained, and those that emerge are the result of highly conserved developmental mechanisms that shape the boundaries and topographic organizations of cortical areas.

Encoding of Coordinated Grasp Trajectories in Primary Motor Cortex
TLDR
The results suggest that neurons encode the covarying trajectories of the hand's joints during a prehensile movement, better described by temporally extensive combinations of finger and wrist joint angle kinematics rather than any individual joint motion or any combination of static kinematic parameters at their optimal lag.

Modulation of primary motor cortex outputs from ventral premotor cortex during visually guided grasp in the macaque monkey
TLDR
Testing the effect of single stimuli delivered through microwires chronically implanted in area F5 and in primary motor cortex of two macaque monkeys found that during visually guided grasp, F5 modulates corticospinal outputs from M1 in a muscle‐ and grasp‐specific manner.
