Touching the void – First and third person perspectives in two cases of autobiographical amnesia linked to temporal lobe epilepsy

Published in: Neuropsychologia, Volume 110, February 2018, 55-64 Abstract “Temporal lobe epilepsy (TLE) can be associated with a marked impairment of autobiographical memory. This is occasionally its presenting feature. We describe two individuals with severe epilepsy-associated autobiographical memory loss. Both MB and PT were reassured initially that their memory was intact on the basis of standard neuropsychological tests. Both […]

Neural and behavioural correlates of autobiographical memory retrieval in patients with major depressive disorder and a history of trauma exposure

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 148-158 Abstract “Alterations in autobiographical memory (AM) performance have been identified in major depressive disorder (MDD) and in trauma-related disorders, however, the neural and behavioural correlates of AM retrieval in patients with MDD and a co-morbid history of trauma remain unexplored. Here, we used behavioural and neuroimaging techniques to investigate AM in this

A short cut to the past: Cueing via concrete objects improves autobiographical memory retrieval in Alzheimer’s disease patients

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 113-122 Abstract “Older adults diagnosed with Alzheimer’s disease (AD) have difficulties accessing autobiographical memories. However, this deficit tends to spare memories dated to earlier parts of their lives, and may partially reflect retrieval deficits rather than complete memory loss. Introducing a novel paradigm, the present study examines whether autobiographical memory recall can

Remembering and imagining alternative versions of the personal past

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 170-179 Abstract “Although autobiographical memory and episodic simulations recruit similar core brain regions, episodic simulations engage additional neural recruitment in the frontoparietal control network due to greater demands on constructive processes. However, previous functional neuroimaging studies showing differences in remembering and episodic simulation have focused on veridical retrieval of past experiences,

Task-related and resting-state fMRI identify distinct networks that preferentially support remembering the past and imagining the future

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 180-189 Abstract “The relation between episodic memory and episodic future thought (EFT) remains an active target of research. A growing literature suggests that similar cognitive processes and neural substrates tend to support these acts. However, direct comparisons of whole-brain activity reveal clear differences, with numerous regions more active when engaging in

Semanticized autobiographical memory and the default – executive coupling hypothesis of aging

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 37-43 Abstract “As we age, the architecture of cognition undergoes a fundamental transition. Fluid intellectual abilities decline while crystalized abilities remain stable or increase. This shift has a profound impact across myriad cognitive and functional domains, yet the neural mechanisms remain under-specified. We have proposed that greater connectivity between

Two years later – Revisiting autobiographical memory representations in vmPFC and hippocampus

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 159-169 Abstract “A long-standing question in memory neuroscience concerns how and where autobiographical memories of personal experiences are represented in the brain. In a previous high resolution multivoxel pattern analysis fMRI study, we examined two week old (recent) and ten year old (remote) autobiographical memories (Bonnici et al., 2012, J. Neurosci. 32:16982–16991). We

Modulation of sensorimotor circuits during retrieval of negative Autobiographical Memories: Exploring the impact of personality dimensions

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 190-196 Abstract “Autobiographical Memory (AM) retrieval refers to recollection of experienced past events. Previous Transcranial Magnetic Stimulation (TMS) studies have shown that presentation of emotional negative stimuli affects human motor cortexexcitability resulting in larger motor evoked potentials (MEPs). Up to date no TMS studies have been carried out in order to investigate the

The precuneus and hippocampus contribute to individual differences in the unfolding of spatial representations during episodic autobiographical memory

Neuropsychologia

Published in: Neuropsychology, Volume 110, February 2018, 123-133 Abstract “Spatial information is a central aspect of episodic autobiographical memory(EAM). Space-based theories of memory, including cognitive map and scene construction models, posit that spatial reinstatement is a required process during early event recall. Spatial information can be represented from both allocentric (third-person) and egocentric (first-person) perspectives during EAM, with egocentric

The life stories of adults with amnesia: Insights into the contribution of the medial temporal lobes to the organization of autobiographical memory

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 84-91 Abstract “Autobiographical memories are not stored in isolation but rather are organized into life chapters, higher-order knowledge structures that represent major themes conveying the arc of one’s life. Neuropsychological studies have revealed that both episodic memory and some aspects of personal semantic memory are impaired in adults with medial temporal lobe (MTL) damage. However,
