Cortical thickness, gyrification and sulcal depth in trigeminal neuralgia
Scientific Reports, 2021 Neuroimaging studies have documented brain structural alterations induced by chronic pain, particularly in gray matter volume. However, the effects of trigeminal neuralgia (TN), a severe paroxysmal pain disorder, on cortical morphology are not yet known.

Functional anatomy of the masking level difference, an fMRI study [PDF]
, 2012 Introduction: Masking level differences (MLDs) are differences in the hearing threshold for the detection of a signal presented in a noise background, where either the phase of the signal or noise is reversed between ears.

Stroke Lesion Segmentation with Visual Cortex Anatomy Alike Neural Nets [PDF]
arXiv, 2021 Cerebrovascular accident, or commonly known as stroke, is an acute disease with extreme impact on patients and healthcare systems and is the second largest cause of death worldwide. Fast and precise stroke lesion detection and location is an extreme important process with regards to stroke diagnosis, treatment, and prognosis.

Anatomical and neurochemical mechanisms of apathy in Parkinson's disease
Chinese Journal of Contemporary Neurology and Neurosurgery, 2018 Apathy is one of the common non-motor symptoms (NMS) in Parkinson's disease (PD), which can be defined as a syndrome of decreased motivation that manifests as a decrease in goal-directed behaviors.

The Kidneys Are Not All Normal: Investigating the Speckle Distributions of Transplanted Kidneys [PDF]
arXiv, 2022 Modelling ultrasound speckle has generated considerable interest for its ability to characterize tissue properties. As speckle is dependent on the underlying tissue architecture, modelling it may aid in tasks like segmentation or disease detection. However, for the transplanted kidney where ultrasound is commonly used to investigate dysfunction, it is ...

Involvement of the cortico-basal ganglia-thalamocortical loop in developmental stuttering [PDF]
, 2019 Stuttering is a complex neurodevelopmental disorder that has to date eluded a clear explication of its pathophysiological bases. In this review, we utilize the Directions Into Velocities of Articulators (DIVA) neurocomputational modeling framework to ...

An anatomy-based V1 model: Extraction of Low-level Features, Reduction of distortion and a V1-inspired SOM [PDF]
arXiv, 2023 We present a model of the primary visual cortex V1, guided by anatomical experiments. Unlike most machine learning systems our goal is not to maximize accuracy but to realize a system more aligned to biological systems. Our model consists of the V1 layers 4, 2/3, and 5, with inter-layer connections between them in accordance with the anatomy.
