Abstract
Pain memory is commonly considered an underlying cause of chronic pain and is also responsible for a range of anxiety. Electroacupuncture (EA) has been shown to ameliorate pain memories and exert anti-anxiety effects. Previous research has indicated that GABAergic neurons and/or GABA receptors (GABARs) in the midcingulate cortex (MCC) have potential associations with chronic pain and anxiety. However, there is no known empirical research that has specifically studied the effects of EA on the GABAergic system in the MCC. Here, we used cross-injection of carrageenan to establish the pain memory rats model. Immunofluorescence were used to detect the excitability of GABAergic neurons within MCC. Von Frey filament, elevated zero maze, and open field tests were used to measure mechanical allodynia and anxiety-like behaviors, combined with chemogenetic and pharmacologic technologies. Finally, this study provides evidence that pain memories contribute to generalized negative emotions and that downregulating the activity of GABAergic neurons within MCC could block pain memories and reverse anxiety emotion. Specifically, GABABR is involved in pain memory and related anxiety-like behaviors. Activation of GABAergic neurons in the MCC did not reverse the effects of EA on pain memories and related anxiety-like behaviors, whereas these effects could be reversed by a GABABR agonist. These findings highlight the functional significance of GABABR in the EA-mediated attenuation of pain memories and related anxiety-like behaviors in rats.

Long-term (statistically learnt) and short-term (inter-trial) distractor-location effects arise at different pre- and post-selective processing stages. Psychophysiology 2023; 60:e14351. [PMID: 37277926 DOI: 10.1111/psyp.14351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 04/24/2023] [Accepted: 04/30/2023] [Indexed: 06/07/2023]
Abstract
A salient distractor interferes less with visual search if it appears at a location where it is likely to occur, referred to as distractor-location probability cueing. Conversely, if the current target appears at the same location as a distractor on the preceding trial, search is impeded. While these two location-specific "suppression" effects reflect long-term, statistically learnt and short-term, inter-trial adaptations of the system to distractors, it is unclear at what stage(s) of processing they arise. Here, we adopted the additional-singleton paradigm and examined lateralized event-related potentials (L-ERPs) and lateralized alpha (8-12 Hz) power to track the temporal dynamics of these effects. Behaviorally, we confirmed both effects: reaction times (RTs) interference was reduced for distractors at frequent versus rare (distractor) locations, and RTs were delayed for targets that appeared at previous distractor versus non-distractor locations. Electrophysiologically, the statistical-learning effect was not associated with lateralized alpha power during the pre-stimulus period. Rather, it was seen in an early N1pc referenced to the frequent distractor location (whether or not a distractor or a target occurred there), indicative of a learnt top-down prioritization of this location. This early top-down influence was systematically modulated by (competing) target- and distractor-generated bottom-up saliency signals in the display. In contrast, the inter-trial effect was reflected in an enhanced SPCN when the target was preceded by a distractor at its location. This suggests that establishing that an attentionally selected item is a task-relevant target, rather than an irrelevant distractor, is more demanding at a previously "rejected" distractor location.

Biol Psychol 2023; 181:108596. [PMID: 37268264 DOI: 10.1016/j.biopsycho.2023.108596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 05/10/2023] [Accepted: 05/30/2023] [Indexed: 06/04/2023]
Abstract
Substantial evidence indicates that feedback processing not only varies with the valence of feedback, but is also highly dependent on contextual factors. Even so, the influence of prior outcome history on current outcome evaluation is far from clear. To investigate this issue, we conducted two event-related potential (ERP) experiments using a modified gambling task whereby each trial was associated with two consequences. In experiment 1, two instances of feedback indicated participant performance on two dimensions of a single decision, within a trial. In experiment 2, participants made two decisions in each trial, and then received two instances of feedback. We examined the feedback-related negativity (FRN) as an index of feedback processing. When both instances of feedback were relevant to the same trial (intra-trial), the FRN to the second was affected by the valence of the immediately previous feedback: The FRN was amplified to losses following wins. This was observed in both experiment 1 and experiment 2. When two instances of feedback were relevant to two different trials (inter-trial), the effect of immediately previous feedback on the FRN was inconsistent. In experiment 1 there was no effect of feedback from the previous trial on the FRN. However, in Experiment 2 there was an effect of inter-trial feedback on the FRN that was opposite to the effect of intra-trial feedback: The FRN was amplified when losses followed losses. Taken together, the findings suggest that the neural systems involved in reward processing dynamically and continuously integrate preceding feedback for the evaluation of present feedback.
