Diagnosed With Dementia, She Documented Her Wishes. They Said No.

Susan Saran was diagnosed with frontotemporal dementia, a progressive, fatal brain disease. After suffering two brain hemorrhages, Saran signed an advance directive for dementia, a controversial new document that instructs caregivers to withhold hand-feeding and fluids at the end of life. She wears a chain bearing instructions that she not be resuscitated.(Heidi de Marco/KHN) ITHACA, […]

Intra- and Inter-subject Variability in EEG-Based Sensorimotor Brain Computer Interface: A Review

Brain computer interfaces (BCI) for the rehabilitation of motor impairments exploit sensorimotor rhythms (SMR) in the electroencephalogram (EEG). However, the neurophysiological processes underpinning the SMR often vary over time and across subjects. Inherent intra- and inter-subject variability causes covariate shift in data distributions that impede the transferability of model parameters amongst sessions/subjects. Transfer learning includes […]

The Musical Structure of Time in the Brain: Repetition, Rhythm, and Harmony in fMRI During Rest and Passive Movie Viewing

Space generally overshadows time in the construction of theories in cognitive neuroscience. In this paper, we pivot from the spatial axes to the temporal, analyzing fMRI image series to reveal structures in time rather than space. To determine affinities among global brain patterns at different times, core concepts in network analysis (derived from graph theory) […]
