Resting-state EEG beta band power predicts quality of life outcomes in patients with depressive disorders: a longitudinal investigation

In this study, resting-state electroencephalograms were taken in patients with depressive disorders. The high beta band power predicted quality of life 3 years later in the patients. The high beta band power may be a useful biomarker for depressive disorders.

Store-operated calcium channels are involved in spontaneous slow calcium oscillations in striatal neurons

Striatal neurons exhibit spontaneous slow Ca2+ oscillations due to Ca2+ release from the Ca2+-store. We show that store-operated calcium channels (SOCCs) exert a functional role and are involved in the slow Ca2+ oscillations in striatal GABAergic neurons. The present results indicate that SOCCs contribute to Ca2+ signaling in striatal GABAergic neurons.

α-Synuclein BAC transgenic mice exhibited RBD-like behaviour and hyposmia: a prodromal Parkinson’s disease model

We created prodromal Parkinson’s disease (PD) mice model exhibiting hyposmia and REM sleep behavior disorders (RBD) as well as α-synuclein deposition and mild dopaminergic cell loss. This mice model can contribute to the development of disease-modifying therapies and preventive treatments in the prodromal stage of PD.

Study finds common abnormalities in the white matter across multiple psychiatric disorders―schizophrenia and bipolar disorder share similar abnormalities

Mega-analyses indicated similar white matter microstructural abnormalities between schizophrenia and bipolar disorder in the limbic system, while autism spectrum disorder also shared abnormalities in the corpus callosum. Major depression showed a relative lack of white matter microstructural defects. Schizophrenia was unique in having defects in discrete neocortical tracks. This study was published in 『Molecular Psychiatry』

Visualization of brain activity in a neuropathic pain model using quantitative activity-dependent manganese magnetic resonance imaging

To elucidate brain regions associated with neuropathic pain, we conducted an activity mapping of a mouse model of neuropathic pain using quantitative activation-induced manganese-enhanced magnetic resonance imaging (qAIM-MRI). qAIM-MRI revealed increased neural activity in the limbic system and sensory-motor, piriform, and insular cortex. This is the first study to demonstrate whole-brain activity mapping in a neuropathic pain model.
