“…The retrieval of autobiographical and word-pair memories differs in that the former often involves the subjective experience of remembering multifaceted events that take place over a sequence of phases, combining features that may be of several modalities and recalled from a first-person point-of-view [51][52][53]. Accordingly, AG has been found to be differentially sensitive to the retrieval of multi-modal spatio-temporal memories compared to those involving only a single sensory modality [54][55][56][57], and to integrate these features within an egocentric perspective [47,58], in a way that is characteristic of true episodic memory [59].…”

The angular gyrus (AG) region of lateral parietal cortex has been implicated in a wide variety of tasks and functions, generating numerous influential theories. However, these theories fail to explain why so many apparently distinct cognitive activities implicate common parietal structures. We propose a unifying model, based on a set of central principles, to account for coalescences of cognitive task activations across AG. To illustrate, we show how these principles account for findings from studies of episodic and semantic memory that have independently implicated the same AG regions but thus far been considered from largely domain-specific perspectives. We conclude that AG computations, as part of a wider lateral parietal system, enable the online dynamic buffering of multi-sensory spatio-temporally extended representations.

“…Although this was interpreted as an impairment of subjective memory in these patients, a reduction in their objective memory for the perceptual details of these recollections, although not tested, may also explain this effect. Of note, Russell et al 56 recently reported that individuals with right hemisphere IPL damage and without unilateral hemispatial neglect symptoms were specifically impaired in recalling their self-perspective at encoding. Contrastingly, these individuals could recall other information about the episode that could be summarised with a label 56 , potentially enabling functional compensation by the left hemisphere's IPL.…”

These studies all suggest that perceptual feature information is more susceptible than semantic/conceptual information to memory impairment when IPL function is compromised.…”

Our understanding of the inferior parietal lobe (IPL) remains challenged by inconsistencies between neuroimaging and neuropsychological perspectives. To date, others assume that hemispheric specialisation of the IPL is linked with the type of processing; attention processing in the right hemisphere; memory retrieval and semantic judgement in the left hemisphere. Here, we provide compelling evidence associating the type of information being processed with the recruitment of each hemisphere’s IPL. In a meta-analysis, we classify 121 previous fMRI reports of IPL activity arising from episodic memory retrieval, according to the type of information that characterises each fMRI contrast. We demonstrate that the left IPL is more consistently associated with retrieval of the semantic (95% of eligible contrasts) than perceptual aspects of memory (83%). In contrast, the right IPL is more consistently associated with the retrieval of perceptual (97%), than semantic aspects of memory (43%). This work revises assumptions of how the IPL contributes to healthy cognition and has major implications for IPL-related neuropsychological deficits.

“…Other research has tested whether angular gyrus is also important for imbuing memories with the characteristic of first-person perspective that Wordsworth evoked so powerfully [8,14,15]. For example, when volunteers were asked to recall autobiographical memories from their personal pasts, participants reported fewer of their memories as being experienced from a first-person perspective following angular gyrus disruption induced by brain stimulation compared with stimulation of a control brain region [8].…”

Highlights (3-5, each 85 characters incl spaces) • Episodic memory can be better understood by considering different levels of analysis • Arts and humanities depictions can inspire scientific investigation of remembering • A multi-level perspective can help address some confusions in the literature • Full understanding of memory requires consideration of social and cultural factors Abstract (100-120 words) Some of the most interesting advances in the study of episodic memory have come from considering different levels of analysis. In this article, we focus on how insights from multiple disciplines can inform understanding of the subjective experience of remembering. For example, we highlight how inspiration from the arts and humanities can generate novel research questions that can elucidate the cognitive and brain mechanisms responsible for what it feels like to remember a previous experience. We also consider how a multi-level perspective can help to address some confusions in the literature, such as between reconsolidation and reconstruction, and how a full understanding of memory requires appreciation of social and cultural factors.
