The present paper considers recent progress in our understanding of the afferent/ascending
neural pathways and neural circuits of interoception. Of particular note is the extensive role …

The past 40 years have witnessed extensive research on fractal structure and scale-free
dynamics in the brain. Although considerable progress has been made, a comprehensive …

Parkinson's disease (PD) is a movement disorder characterized by the early loss of
nigrostriatal dopaminergic pathways producing significant network changes impacting motor …

Aging is accompanied by a host of social and biological changes that correlate with
behavior, cognitive health and susceptibility to neurodegenerative disease. To understand …

The properties of the cell types that are selectively vulnerable in Huntington's disease (HD)
cortex, the nature of somatic CAG expansions of mHTT in these cells, and their importance …

Mapping structural spatial change (ie, gradients) in the striatum is essential for
understanding the function of the basal ganglia in both health and disease. We developed a …

Diffusion tensor imaging (DTI) allows measuring fractional anisotropy and similar
microstructural indices of the brain white matter. Lower than normal fractional anisotropy as …

Introduction Functional MRI with spatial resolution in the submillimeter domain enables
measurements of activation across cortical layers in humans. This is valuable as different …

Transcranial magnetic stimulation (TMS)‐evoked potentials (TEPs) are a promising proxy for
measuring effective connectivity, that is, the directed transmission of physiological signals …

Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) are two
devastating and fatal neurodegenerative conditions. While distinct, they share many clinical …
