Time-varying effects of neuropathologies on the trajectory of late life cognitive decline
Using clinical-pathological data from more than 1000 individuals, Boyle et al. show that some age-related neuropathologies contribute to progressive cognitive deterioration, whereas others impair cognition but exert relatively stable effects over time.
COL6A5 variants in familial neuropathic chronic itch
Chronic idiopathic itch is often diagnosed as a psychogenic disorder. Boneschi et al. report an association between idiopathic chronic itch and COL6A5 in several multigenerational families with small fibre neuropathy.Full text version
Synaptic inputs from stroke-injured brain to grafted human stem cell-derived neurons activated by sensory stimuli
Tornero et al. demonstrate that intracortical grafts of human skin-derived cortical neurons restore specific connections in stroke-injured cortex of rodents, and respond to tactile stimulation of nose and paw.

Patients with brain injuries scored much lower than the healthy population at baseline on two measures of working memory. However, after four sessions of hypnosis, they improved on both outcome measures to slightly above the population mean.
