Greater Attention to Task-Relevant Threat Due to Orbitofrontal Lesion

Abstract: Injury to the orbitofrontal cortex (OFC) is a frequent consequence of head injury and may lead to dysfunctional regulation of emotional and social behavior. Dysfunctional emotional behavior may partly be related to the role of the OFC in emotion-attention interaction, as reported previously. In order to better understand its role in emotion-attention and emotion-cognitive control interactions, we investigated attention allocation to task-relevant and task-irrelevant threat-related emotional stimuli during a ta… Show more

“…Here, subjects committed more errors than controls in an implicit version of the AAT, which is suggestive of difficulties in ignoring task-irrelevant stimulus features. This observation concurs with other studies in showing that OFC patients are more susceptible to distraction by to-be-ignored stimulus characteristics (Mäki-Marttunen et al 2017;Kuusinen et al 2018), and agrees with the general idea that OFC damage hinders the implementation of goal-directed behavior (Rudebeck and Rich 2018). Moreover, error rates were associated with greater self-reported impulsivity and disinhibition in OFC patients, as well as with worse emotional control and self-monitoring.…”

“…Frontocortical activation, including OFC, has been implicated in processing anxiety and anxiety-dependent cognitive traits of attention and impulsivity, all of which are strongly dysregulated in nicotine dependence (Gold et al, 2015;Rauch et al, 2007;Ursu and Carter, 2009). Additionally, patients with OFC damage display deficits in attentional control specifically in response to emotional stimuli (Hartikainen et al, 2012;Maki-Marttunen et al, 2017). Thus, nicotine-induced alterations in OFC neuronal plasticity together with activity in associated corticolimbic structures (eg, hippocampus, amygdala) that are engaged in affective decision processes, might contribute to anxiety-related cognitive bias towards no-go signals.…”

“…However, neuropsychological tests typically fail to capture any deficits in attentional, executive or affective functions in patients with lesion to OFC despite their self-reported occurrence (Manes et al, 2002 ; Zald and Andreotti, 2010 ). Alterations in emotion-attention and emotion-cognitive control interactions have been observed in these patients with event-related potentials (ERPs; Hartikainen et al, 2012a ; Mäki-Marttunen et al, 2017 ), suggesting a lack of sensitivity on the part of traditional testing methods. More detailed knowledge, including possible changes in the dynamics of these interactions, is needed for further insight into the neural basis underlying the behavioral, emotional and cognitive challenges these patients encounter as well as for developing accurate assessment and targeted rehabilitation tools for them.…”
