“…More recently, it has been advanced the hypothesis that the RH processes all basic emotions (positive and negative) and is the seat of subjective affect (feeling) [2][3][4][5][6]. In regard to the left hemisphere (LH), contradictory findings make its contributions to emotional processing highly debatable (i.e., whether the LH does not differentiate between emotional and neutral faces [7] or only processes positive emotions [2]).…”

“…Elizabeth Shobe (2014) proposed a qualitatively different involvement of each hemisphere in emotional processing. According to her model, the RH directly mediates the identification and comprehension of positive and negative emotional stimuli, whereas the LH contributes to higher level processing of emotional information that has been shared via the corpus callosum, so that Bthe complex processing of and responding to emotions require a cross-hemispheric collaboration that originates in the RH, and this is particularly true for negative emotions^ [6].…”

“…The right amygdala-pulvinar-colliculus pathway would subserve automatic or unconscious processing of emotional stimuli and subsequent activation for physiological preparation. The cortico-pulvinar-cortical pathway would provide Bthe preliminary link between the immediate fast and coarse subcortical processing and the cortical processing of emotion^, enabling a cross-callosal transfer of emotional information from the RH to the LH [6].…”

Inability to Process Negative Emotions in Cerebellar Damage: a Functional Transcranial Doppler Sonographic Study

Recent studies have implicated the cerebellum as part of a circuitry that is necessary to modulate higher order and behaviorally relevant information in emotional domains. However, little is known about the relationship between the cerebellum and emotional processing. This study examined cerebellar function specifically in the processing of negative emotions. Transcranial Doppler ultrasonography was performed to detect selective changes in middle cerebral artery flow velocity during emotional stimulation in patients affected by focal or degenerative cerebellar lesions and in matched healthy subjects. Changes in flow velocity during non-emotional (motor and cognitive tasks) and emotional (relaxing and negative stimuli) conditions were recorded. In the present study, we found that during negative emotional task, the hemodynamic pattern of the cerebellar patients was significantly different to that of controls. Indeed, whereas relaxing stimuli did not elicit an increase in mean flow velocity in any group, negative stimuli increased the mean flow velocity in the right compared with left middle cerebral artery only in the control group. The patterns by which mean flow velocity increased during the motor and cognitive tasks were similar within patients and controls. These findings support that the cerebellum is part of a network that gives meaning to external stimuli, and this particular involvement in processing negative emotional stimuli corroborates earlier phylogenetic hypotheses, for which the cerebellum is part of an older circuit in which negative emotions are crucial for survival and prepare the organism for rapid defense.

“…Recently, Shobe (2014) argued that though either hemisphere could process positive emotions, they need to collaborate to process negative emotions. Yet, in another study, Rochas and colleagues (Rochas, Rihs, Rosenberg, Landis, & Michel, 2014) provided evidence for the specific contributions of the RH while processing emotional words.…”

“…Elizabeth Shobe's article, Independent and Collaborative Contributions of the Cerebral Hemispheres to Emotional Processing (Shobe, 2014) proposes a framework for understanding the interaction of lateralized brain mechanisms for identifying and understanding emotional stimuli and engaging in higher-order emotional processing. Under this framework, the right hemisphere engages subcortical structures with the goal of identifying and comprehending positive and negative emotional stimuli, whereas the left hemisphere contributes to higher-level processing such as emotion regulation and adaptation.…”

The goal of this Research Topic was to bring together diverse scientific perspectives on lateralized brain mechanisms underlying emotion, motivation, and memory. The Topic resulted in eight articles, three of which report original research and five of which review and synthesize past research with the aim of developing new hypotheses and theory. A range of international experts with diverse backgrounds, theoretical perspectives, and experimental methods contributed to the Topic. Contributions strongly reflect this diversity, ranging from examining pupil dilation in response to viewing Rembrandt portraits to understanding how caffeine supplementation influences levels of spatial processing. In all cases, the authors developed strong, empirically guided insights into the lateralized brain mechanisms underlying behavioral effects. Two primary themes emerge to guide and constrain continuing research.The first theme is related to dynamic interhemispheric interactions that subserve emotion, motivational states, and memory. Elizabeth Shobe's article, Independent and Collaborative Contributions of the Cerebral Hemispheres to Emotional Processing (Shobe, 2014) proposes a framework for understanding the interaction of lateralized brain mechanisms for identifying and understanding emotional stimuli and engaging in higher-order emotional processing. Under this framework, the right hemisphere engages subcortical structures with the goal of identifying and comprehending positive and negative emotional stimuli, whereas the left hemisphere contributes to higher-level processing such as emotion regulation and adaptation. Critically, dynamic interhemispheric interactions provide the left hemisphere with the information it needs to execute relatively strategic processes. Spielberg and colleagues emphasize the importance of lateralized approach versus avoidance networks in guiding human behavior. In their article, Hierarchical Brain Networks Active in Approach and Avoidance Goal Pursuit (Spielberg et al., 2013), the authors propose a hierarchical model consisting of four levels: tactical, strategic, system, and temperamental, following a neurally inspired abstraction gradient along posterior to anterior areas of the prefrontal cortex. Right hemisphere regions process and update avoidance goals, and left hemisphere regions govern approach goals. The model dictates both intrahemispheric interactions across hierarchical layers, and also interhemispheric interactions that cut across both abstraction levels and motivational states; together, these interactions guide, constrain, and update goal-directed behavior over time. (Parker et al., 2013), demonstrating that horizontal saccadic eye movements enhance episodic but not semantic autobiographical memory retrieval. In accounting for these results, the authors point to the hemispheric encoding/retrieval asymmetry (HERA; Habib et al., 2003) model and its suggestion that episodic memory retrieval depends on efficient and dynamic interhemispheric interactions. They also suggest that saccadic...
