Fornix subdivisions and spatial learning: a diffusion MRI study

Carl J. Hodgetts, Mark Postans, Angharad N. Williams, Kim S. Graham et autres

The fornix is the major fibre pathway linking the hippocampal formation with distal brain sites. Human and animal lesion studies show that the connections comprising the fornix are vital for specific attributes of episodic and spatial memory. The fornix, however, interconnects the …

TAP-I Deficiency Presenting With Chronic Granulomatous Rubella Virus-Driven Cutaneous Ulceration: A Case Report and Scoping Literature Review

Mark Ponsford, Emily Carne, Kathryn Bramhall, Kristin Ladell et autres

Abstract Autosomal recessive mutations in TAP1, TAP2, TAPBP, or B2M , are associated with major histocompatibility complex (MHC) class I deficiency. Individuals may present with granulomatous skin ulceration, but the underlying antigenic triggers remain largely unknown. We identified TAP1 deficiency in a …

Individual differences in experiential diversity shape event segmentation granularity

Carl J. Hodgetts, Samuel C. Berry, Mark Postans, Angharad N. Williams

Parsing experience into meaningful events or units, known as event segmentation, may be critical for structuring episodic memory, planning, and navigating spatial and social environments. However, little is known about what factors shape inter-individual differences in event segmentation. Here, we show that …

Fornix subdivisions and spatial learning: a diffusion MRI study

Carl J. Hodgetts, Mark Postans, Angharad N. Williams, Kim S. Graham et autres

Abstract The fornix is the major white matter tract linking the hippocampal formation with distal brain sites. Human and animal lesion studies show that the connections comprising the fornix are vital for specific attributes of episodic and spatial memory. The fornix, however, …

Ultra-high-field 7T MRI reveals changes in human medial temporal lobe volume in female adults during menstrual cycle

Rachel G. Zsido, Angharad N. Williams, Cláudia Barth, Bianca Serio et autres

Abstract Ovarian hormones have substantial effects on the brain, and early menopause has been associated with increased risk of accelerated brain aging and dementia later in life. However, the impact of ovarian hormone fluctuations on brain structure earlier in life is less …

The structure of experience: Examining the emergence of schematic representations in the medial prefrontal cortex

Philipp C. Paulus, Angharad N. Williams, Sina S. Wiese, Roland G. Benoit

The hippocampus supports the retention of unique experiences as episodic memories. In contrast, neocortical regions including the medial prefrontal cortex (mPFC) have been argued to support the retention of more generalized memory representations, i.e., memory schemas. These representations are thought to be …

Longitudinal 7T MRI reveals volumetric changes in subregions of human medial temporal lobe to sex hormone fluctuations

Rachel G. Zsido, Angharad N. Williams, Cláudia Barth, Bianca Serio et autres

The hippocampus and surrounding medial temporal lobe (MTL) are critical for memory processes, with local atrophy linked to memory deficits. Animal work shows that MTL subregions densely express sex hormone receptors and exhibit rapid structural changes synchronized with hormone fluctuations. Such transient …

Neurofeedback Training versus Treatment-as-Usual for Alcohol Dependence: Results of an Early-Phase Randomized Controlled Trial and Neuroimaging Correlates

Leena Subramanian, Léon Skottnik, W. Miles Cox, Michael Lührs et autres

INTRODUCTION: Alcohol dependence is one of the most common substance use disorders, and novel treatment options are urgently needed. Neurofeedback training (NFT) based on real-time functional magnetic resonance imaging (rtf-MRI) has emerged as an attractive candidate for add-on treatments in psychiatry, but …
