Neural correlates and determinants of approach–avoidance conflict in the prelimbic prefrontal cortex

Abstract: The recollection of environmental cues associated with threat or reward allows animals to select the most appropriate behavioral responses. Neurons in the prelimbic cortex (PL) respond to both threat- and reward-associated cues. However, it remains unknown whether PL regulates threat-avoidance vs. reward-approaching responses when an animals' decision depends on previously associated memories. Using a conflict model in which male Long-Evans rats retrieve memories of shock- and food-paired cues, we observed two… Show more

“…Adding to the known involvement of the RSC 55,56 and the Re 5759 in modulating fear memory formation and expression, our results revealed neural activity in these structures was increased during mild memory recall, but not during strong memory recall, when compared to unshocked controls. Although the hippocampus 48,49,6062 , prelimbic 6365 , and cingulate cortex 6668 are critical to contextual fear memory-related processes, we found no differences in their activation between groups, suggesting that the role of these structures in modulating the expression of fear of different intensities may not reflect in changes in overall activation levels.…”

“…So, PVT could contribute to these changes in reward salience ( Zhu et al, 2018 ; Campus et al, 2019 ), response caution, or both. The PL is critical for approach–avoid decision-making ( Verharen et al, 2019 ; Kyriazi et al, 2020 ; Fernandez-Leon et al, 2022 ) and a major source of excitatory glutamatergic inputs driving PVT neuronal activity ( Vertes, 2002 ; Li and Kirouac, 2012 ; Otis et al, 2019 ). We hypothesized that the role of PVT likely depended on this prefrontal input.…”

“…The prelimbic cortex (PL) is well established in approach–avoid decision-making ( Verharen et al, 2019 ; Kyriazi et al, 2020 ; Fernandez-Leon et al, 2022 ). For example, activity of PL units during conflict reflects a variety of task variables (valence, trial identity, response) ( Kyriazi et al, 2020 ) that contribute to individual approach–avoid decisions ( Fernandez-Leon et al, 2022 ) and specifically control approach behaviors under threat ( Verharen et al, 2019 , 2020 ). These roles are due, at least in part, to prefrontal interactions with amygdala and striatum ( Verharen et al, 2019 , 2020 ; Kyriazi et al, 2020 ).…”

“…Additionally, in males, there was a positive correlation between alcohol seeking and neural activation in the mOFC, PrL, dBNST, NAcC, NAcSh, PVT, LHb, vSUB, and DG. These are all key regions implicated in learning, decision-making, reward seeking, punishment, and approach-avoidance behavior (Bannerman et al, 2004; Ch’ng et al, 2018; Fernandez-Leon et al, 2021; Haight & Flagel, 2014; Hsu et al, 2014; Kaouane et al, 2021; Marchant et al, 2016; McDannald et al, 2014; Rhodes & Murray, 2013; Rivera et al, 2019). Contrastingly, there were no correlations found in the females.…”
