The rapid antidepressant actions of low dose ketamine occur through the direct relief of suppression of protein synthesis via antagonism of a subset of NMDA receptors containing the GluN2B subunit.
Serotonin neurons in chronically isolated mice become less responsive to excitatory stimulation, but inhibiting a distinctive calcium-activated potassium channel can restore both neuronal activity and behavior.
The orphan receptor GPR158 is highly regulated by stress exposure and acts on key neuronal signaling pathways in the prefrontal cortex to control depressive-like behaviors.
Gut microbiota can influence mPFC transcriptional profiles and myelin content, overriding the impact of genetic background in the development of social avoidance behavior.
In mouse brain slices, native delta glutamate receptors carry ionic current and underlie the α1-adrenergic receptor-mediated depolarization of dorsal raphe neurons that drives action potential firing in vivo.
Truncated Disrupted-in-schizophrenia 1 (Disc 1) ablates signaling of parvalbumin-expressing interneurons in the prefrontal cortex and underlies depression-related behaviour in mice.
1H-Magnetic resonance spectroscopy at 14T reveals a metabolic signature for anti-depressant-like effects of acetyl-L-carnitine in nucleus accumbens of susceptible mouse.
Inspired by the sparse, sequential neural activity patterns observed in striatum, a new circuit model implements variable-speed activity, the encoding of multiple sequences, and a tutor/student relationship between cortex and striatum.
