“…In general, some “pre-attentive” discrimination of visual features related to emotional facial expressions is possible for faces presented in the periphery (e.g., Pizzagalli et al, 1999 ; Rigoulot et al, 2011 , 2012 ; Calvo et al, 2014 ; Towler and Eimer, 2015 ). Yet, the peripheral presentation of our faces might have impeded effects in later occurring ERPs, as peripheral presentation of faces at both peripheral locations somehow masks the strongly delayed ipsi- vs. contralateral ERPs (see Takamiya et al, 2020 ; Schindler et al, 2022 ). Also for centrally presented well visible fearful faces (presented for 50–100 ms; unmasked), differential effects disappear at the level of the N2/EPN when attending to overlaid perceptual information ( Schindler et al, 2020a ; Steinweg et al, 2021 ) or under conditions of peripheral load (e.g., see Schindler et al, 2020b , 2021 ).…”

Do Subliminal Fearful Facial Expressions Capture Attention?

In two experiments, we tested whether fearful facial expressions capture attention in an awareness-independent fashion. In Experiment 1, participants searched for a visible neutral face presented at one of two positions. Prior to the target, a backward-masked and, thus, invisible emotional (fearful/disgusted) or neutral face was presented as a cue, either at target position or away from the target position. If negative emotional faces capture attention in a stimulus-driven way, we would have expected a cueing effect: better performance where fearful or disgusted facial cues were presented at target position than away from the target. However, no evidence of capture of attention was found, neither in behavior (response times or error rates), nor in event-related lateralizations (N2pc). In Experiment 2, we went one step further and used fearful faces as visible targets, too. Thereby, we sought to boost awareness-independent capture of attention by fearful faces. However, still, we found no significant attention-capture effect. Our results show that fearful facial expressions do not capture attention in an awareness-independent way. Results are discussed in light of existing theories.

“…To date, much less work has been done on mapping nonlanguage functions-and the notion of non-eloquence in brain areas outside of dominant hemisphere language regions needs to be challenged. The right hemisphere is known to play an important role in visual perception and spatial processing (173,174), object/face recognition (155,158,(175)(176)(177)(178), socioemotional processing (7), navigation and learning in a spatial context (179), and attention/neglect (180), and there is great need to develop tasks to assess these functions for the purposes of stimulation mapping.…”

Cognitive and Emotional Mapping With SEEG

et al. 2021

Mapping of cortical functions is critical for the best clinical care of patients undergoing epilepsy and tumor surgery, but also to better understand human brain function and connectivity. The purpose of this review is to explore existing and potential means of mapping higher cortical functions, including stimulation mapping, passive mapping, and connectivity analyses. We examine the history of mapping, differences between subdural and stereoelectroencephalographic approaches, and some risks and safety aspects, before examining different types of functional mapping. Much of this review explores the prospects for new mapping approaches to better understand other components of language, memory, spatial skills, executive, and socio-emotional functions. We also touch on brain-machine interfaces, philosophical aspects of aligning tasks to brain circuits, and the study of consciousness. We end by discussing multi-modal testing and virtual reality approaches to mapping higher cortical functions.

“…Faces are relevant for the research question since they evoke-at least when presented in the middle of the screen-increased bilateral P1 and N170 components (Allison et al, 1999;e.g., see Bentin et al, 1996;Neumann et al, 2011). Typically, ipsilateral P1 and N170 components peak later than their contralateral counterparts (see Sadeh & Yovel, 2010;Takamiya et al, 2020). The P1 shows a contralateral enhancement (Rigoulot et al, 2012), especially for left hemifield stimulation (Rigoulot et al, 2011).…”

“…The stimuli were presented in the lower visual field, where stimuli elicit a C1 amplitude (~60-90 ms after stimulus onset, Di Russo et al, 2002Russo et al, , 2003, followed by an early C2 negativity (Capilla et al, 2016). Since the contralateral P1 peaks earlier than the ipsilateral P1 (see Capilla et al, 2016;Sadeh & Yovel, 2010;Takamiya et al, 2020), earlier effects might have overlapped or even canceled out the contralateral but not the ipsilateral positivity. Thus, studies should examine peripheral stimulus positions on the horizontal midline since, for these locations, no profound C1 or later negativity is reported (Capilla et al, 2016).…”
