Alterations in microglial morphology concentrate in the habitual sleeping period of the mouse

Glia, Volume 71, Issue 2, Page 366-376, February 2023., 2023
Main Points We found regional differences of microglial morphology between the somatosensory cortex (SC), hippocampus (HC) and basal forebrain (BF). Cortical‐, but not HC‐ or BF microglial cell sizes negatively correlate with non‐REM sleep slow wave activity.

Neocortical substrates of feelings evoked with music in the ACC, insula, and somatosensory cortex

Scientific Reports, 2021
Neurobiological models of emotion focus traditionally on limbic/paralimbic regions as neural substrates of emotion generation, and insular cortex (in conjunction with isocortical anterior cingulate cortex, ACC) as the neural substrate of feelings.

Energy demands of diverse spiking cells from the neocortex, hippocampus, and thalamus [PDF]

Frontiers in Computational Neuroscience, Volume 8, Pages 41, 2014, 2017
It has long been known that neurons in the brain are not physiologically homogeneous. In response to current stimulus, they can fire several distinct patterns of action potentials that are associated with different physiological classes ranging from regular-spiking cells, fast-spiking cells, intrinsically bursting cells, and low-threshold cells.

The Longitudinal Relationship Between Pain and Depression in People with Inflammatory Arthritis: a Narrative Review

Arthritis Care &Research, Accepted Article.
As many patients with inflammatory arthritis (IA) have chronic pain, understanding how to best assess and manage pain in IA is a priority. Co‐morbid depression is prevalent in adults with IA, affecting 15 to 39% of people. Whilst pain and depression are thought to be associated in IA, this concept is largely based on cross‐sectional data.

A subset of OPCs do not express Olig2 during development which can be increased in the adult by brain injuries and complex motor learning

Glia, Volume 71, Issue 2, Page 415-430, February 2023., 2023
Main Points A subset of OPCs do not express Olig2, of which population peaks in the juvenile brain while wanes with age. Plastic changes of the brain by acute injuries or complex motor learning stop the expression of Olig2 in OPCs. Abstract Oligodendrocyte precursor cells (OPCs) are uniformly distributed in the mammalian brain; however, their function ...

Voxel-based lesion-symptom mapping of stroke lesions underlying somatosensory deficits

NeuroImage: Clinical, 2016
The aim of this study was to investigate the relationship between stroke lesion location and the resulting somatosensory deficit. We studied exteroceptive and proprioceptive somatosensory symptoms and stroke lesions in 38 patients with first-ever acute ...

Conducting Polymer Microelectrode Arrays for Simultaneous Electrophysiology and Advanced Brain Imaging

Advanced Functional Materials, EarlyView.
A flexible micro‐electrocorticography array with PEDOT:SS electrodes is shown to be compatible with ultra‐high magnetic field MRI up to 9.4 T. Multimodal brain monitoring is demonstrated by performing simultaneous blood oxygen level‐dependent functional MRI in parallel with electrophysiology.

The cutaneous rabbit illusion affects human primary sensory cortex somatotopically.

PLoS Biology, 2006
We used functional magnetic resonance imaging (fMRI) to study neural correlates of a robust somatosensory illusion that can dissociate tactile perception from physical stimulation.

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

Advanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Long‐term musical training induces white matter plasticity in emotion and language networks

Human Brain Mapping, Volume 44, Issue 1, Page 5-17, January 2023., 2023
Musical training (both voice and piano) could enhance connectivity among emotion‐related regions of the brain, such as the amygdala. Voice training reshaped the architecture of experience‐dependent networks, such as those involved in vocal motor control, sensory feedback, and language processing. Long‐term musical training can strengthen or prune white
