A Discovery and Replication Study of Dyslexia Does Not Reveal Reproducible Gray Matter Volume Differences

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
This study shows that gray matter volume (GMV) differences in dyslexia fail to replicate across two studies in large, representative samples, and reproducibility of results is dependent on analytic choices, particularly whether total GMV is accounted for. Prior GMV findings in dyslexia should therefore be considered with caution.

Voxel Based Morphometry, implementation and sensitivity [PDF]

, 2003
Voxel-Based Morphometry (VBM) is a whole-brain, unbiased technique for characterising regional cerebral volume and tissue concentration differences in structural magnetic resonance images (MRI), between or within groups of subjects.

Neuroanatomy of Shared Conversational Laughter in Neurodegenerative Disease

Frontiers in Neurology, 2018
Perceiving another person's emotional expression often sparks a corresponding signal in the observer. Shared conversational laughter is a familiar example. Prior studies of shared laughter have made use of task-based functional neuroimaging.

Gray matter correlates of creative potential: A latent variable voxel-based morphometry study

NeuroImage, 2015
There is increasing research interest in the structural and functional brain correlates underlying creative potential. Recent investigations found that interindividual differences in creative potential relate to volumetric differences in brain regions ...

Standard Model Imaging in the Brain and Spinal Cord of MS Patients: Initial Assessment and Comparison to Diffusion Tensor Imaging

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
DTI and SMIfw diffusion models applied in persons with multiple sclerosis revealed region‐specific sensitivity to microstructural injury, but performance differed by anatomical region. SMIfw neurite density fraction demonstrated high sensitivity and reliability in both the brain and spinal cord, whereas DTI measures such as fractional anisotropy and ...

Brain and cognitive correlates of subjective cognitive decline-plus features in a population-based cohort

Alzheimer’s Research & Therapy, 2018
Background Subjective cognitive decline (SCD) consists of self-perceived decline in cognition over time. The occurrence of specific additional features in SCD (so-called SCDplus) confers a higher risk of future cognitive decline. However, it is not known

Lucid Dreaming Frequency Associated With Grey–White Matter Networks: An Exploratory Multimodal MRI Study

Journal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT Lucid dreaming, defined as the experience of becoming aware of dreaming while dreaming, offers a unique window into a state of consciousness characterised by a blending of the sensory vividness of REM sleep with the self‐awareness of wakefulness. While past functional imaging has shed light on the neural activity supporting lucid dreaming, the

Voice processing in dementia: a neuropsychological and neuroanatomical analysis. [PDF]

, 2011
Voice processing in neurodegenerative disease is poorly understood. Here we undertook a systematic investigation of voice processing in a cohort of patients with clinical diagnoses representing two canonical dementia syndromes: temporal variant ...

Neural substrates of the ability to recognize facial expressions: a voxel-based morphometry study

Social Cognitive and Affective Neuroscience, 2016
The recognition of facial expressions of emotion is adaptive for human social interaction, but the ability to do this and the manner in which it is achieved differs among individuals.

Brainstem and Cerebellar Volume Loss and Associated Clinical Features in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1346-1356, July 2026.
ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.
