Intrinsic adaptive plasticity in mouse and human sensory neurons.

In response to changes in activity induced by environmental cues, neurons in the central nervous system undergo homeostatic plasticity to sustain overall network function during abrupt changes in synaptic strengths. Homeostatic plasticity involves changes in synaptic scaling and regulation of intrinsic excitability. Increases in spontaneous firing and excitability of sensory neurons are evident in some forms of chronic pain in animal models and human patients.

Depression and sports-related concussion: A systematic review.

Context: Head injuries are risk factors for chronic depressive disorders, but this association remains poorly explored with regards to concussion.

Objectives: The objective of this review was to evaluate the incidence of depressive symptoms and depression after sports-related concussion. We also endeavored to identify the response elements regarding the pathophysiology of these symptoms.

The unresolved fine structure resolved: IRIS observations of the solar transition region.

The heating of the outer solar atmospheric layers, i.e., the transition region and corona, to high temperatures is a long-standing problem in solar (and stellar) physics.

On the prevalence of small-scale twist in the solar chromosphere and transition region.

The solar chromosphere and transition region (TR) form an interface between the Sun's surface and its hot outer atmosphere. There, most of the nonthermal energy that powers the solar atmosphere is transformed into heat, although the detailed mechanism remains elusive. High-resolution (0.
