The late positive component or late positive complex (LPC) is a positive-going event-related brain potential (ERP) component that has been important in studies of explicit recognition memory. [1][2] It is generally found to be largest over parietal scalp sites (relative to reference electrodes placed on the mastoid processes), beginning around 4...

Sep 1, 2020 · The LPP is a relative positivity in the ERP that begins as early as 200 ms after stimulus onset and is pronounced at centro-parietal recording sites. It is increased for emotional compared with neutral stimuli ranging from pictures, faces and words.

One such neural marker may be the late positive potential (LPP), which is a scalp-recorded event-related potential reflecting facilitated attention to emotional stimuli. In adults, the LPP is reduced following use of cognitive emotion regulation strategies such as reappraisal.

Jun 1, 2022 · The late positive potential (LPP) is a positive-going deflection in the ERP waveform that begins approximately 400 ms after stimulus onset. It is larger for emotional compared to neutral stimuli, and appears to be sensitive primarily to arousal level rather than valence (Cuthbert et al., 2000; Hajcak and Foti, 2020).

This article focuses on two components of the event-related potential (ERP)--the P300 and the late positive potential (LPP)--and how they can be used to understand the interaction between the more automatic and controlled processing of emotional stimuli.

Feb 27, 2012 · The late positive potential (LPP) is an event-related potential (ERP) component over visual cortical areas that is modulated by the emotional intensity of a stimulus. However, the functional significance of this neural modulation remains elusive.

Oct 1, 2023 · In this paper, I build on frameworks that suggest a close relationship between the LPP and the P300 component of the ERP to argue that the classic context updating account of the P300 may provide insights into the function of the LPP.

Neural Signature of Emotion regulation: Late Positive Potential. The LPP is an ERP which can be described as a slow, positive-going waveform that emerges around 200–300 ms after stimulus onset (Hajcak and Dennis, 2009; Hajcak et al., 2010; Kujawa et al., 2012).

Oct 17, 2012 · A key feature observed in ERPs evoked by emotionally engaging stimuli is the late positive potential (LPP), which is characterized by an amplitude enhancement for pleasant and unpleasant stimuli, relative to neutral stimuli, and has a centroparietal maximum topography.

The current study assesses the late positive potential (LPP), an event-related potential sensitive to the modulation of emotional responses, as a neurocognitive signature of regulatory flexibility by examining it in relation to self-reported ER and emotional adjustment.
