“…For most of the areas found to be involved in face processing in our study, white matter connections are present as shown in previous work on face networks (Gschwind et al., ; Ishai, ; Pyles et al., ). The Talairach coordinates (and Brodmann areas, BA) of the left hemisphere sources from RERPs (for details, Kashyap et al., ) are at Occipital Lobe (−37, −70, −5; BA19), Fusiform Gyrus (−40, −49, −16; BA37), Mediotemporal Lobe (−15, −42, −1; BA30), Prefrontal Cortex (−14, 48, 22; BA9), and Anterior Temporal Lobe (−32, 5, −17; BA38), as confirmed with the Talairach client available at http://www.talairach.org/, and converted to MNI coordinates for connections to be delineated across them.…”

“…By following a sequential source fitting strategy for RIDE‐derived latency‐corrected ERPs, Kashyap et al. () localized bilateral face processing areas in ascending temporal order. As compared with other approaches, sequential source fitting has the advantage to provide both (a) source waveforms (SWFs) that can be analysed like surface waveforms, as well as (b) information on the sequence of activity across a network of distinct brain areas corresponding to successive ERP components.…”

“…Within both hemispheres Kashyap et al. () observed priming effects in all RERP sources; the priming effects in different sources temporally overlapped, suggesting parallel and distributed processing (PADP) of facial information across different brain areas. These findings are in compliance with intracranial recordings made in the face recognition study for famous and unfamiliar faces by Barbeau et al.…”

Repetition priming, that is, the repeated processing of a stimulus, facilitates performance. However, the neural underpinnings of repetition priming for famous faces in terms of effective connectivity are not known. Here we investigated this problem using dynamic causal modelling of latency‐corrected event‐related brain potentials (RERPs). Source waveforms of RERP‐derived sources in the Occipital Lobe, Fusiform Gyrus, Mediotemporal Lobe, Prefrontal Cortex and Anterotemporal Lobe of each hemisphere entered into models with only forward (F) or also with backward (FB) connections. Based on the framework of predictive coding formulated for repetition suppression, modulations of F and FB connections were expected for sources that displayed priming effects in their source waveforms. Hence, neural sources in each hemisphere were fitted with either F or FB connections. Inter‐hemispheric connections were considered between homologous areas and were allowed to be modulated in an incremental manner resulting in a model space that comprised of 24 models. Bayesian model averaging across models revealed effective bidirectional connectivity between the Fusiform Gyrus (face perception) and Prefrontal Cortex (decision‐making) in both hemispheres to be modulated by priming. In the left hemisphere, there is also a substantial involvement from the Mediotemporal Lobe, indicating the facilitation of automatic retrieval of the famous person's name. Furthermore, there is evidence that the priming is supported by connections from the right to the left Fusiform Gyri possibly in the service of inter‐hemispheric cooperation. Altogether, the study indicates that along with top–down modulations, efficient processing within and across the two hemispheres is crucial for famous face priming.

The predominant role of the primary motor cortex (M1) in motor execution is well acknowledged. However, additional roles of M1 are getting evident in humans owing to advances in noninvasive brain stimulation (NIBS) techniques. This review collates such studies in humans and proposes that M1 also plays a key role in higher cognitive processes. The review commences with the studies that have investigated the nature of connectivity of M1 with other cortical regions in light of studies based on NIBS. The review then moves on to discuss the studies that have demonstrated the role of M1 in higher cognitive processes such as attention, motor learning, motor consolidation, movement inhibition, somatomotor response, and movement imagery. Overall, the purpose of the review is to highlight the additional role of M1 in motor cognition besides motor control, which remains unexplored.
