Major depressive disorders impact approximately 17% of the population worldwide, whose high morbidity and considerable adversity have resulted in enormous social and economic burden. In addition, clinically depressed patients often show reduced volume of olfactory bulb (OB) and decreased olfactory sensitivity. Although mounting evidence conveyed that the gut microbiota may implicate the pathophysiology of major depressive disorder (MDD) via the microbe-gut-brain axis, knowledge about its distinctive molecular mechanism is rudimentary.

Neurophysiological accounts of human volition are dominated by debates on the origin of voluntary choices but the neural consequences that follow such choices remain poorly understood. For instance, could one predict whether or not an action was chosen voluntarily based only on how that action is motorically executed? We investigated this possibility by integrating scalp electroencephalograms and index-finger accelerometer recordings acquired while people chose between pressing a left or right button either freely or as instructed by a visual cue. Even though freely selected and instructed actions were executed with equal vigor, the timing of the movement to release the button was comparatively delayed for freely selected actions. Read More

The efficacy of cognitive training is controversial, and research progress in the field requires an understanding of factors that promote transfer of training gains and their relationship to changes in brain activity. One such factor may be adaptive task difficulty, as adaptivity is predicted to facilitate more efficient processing by creating a prolonged mismatch between the supply of, and the demand upon, neural resources. To test this hypothesis, we measured behavioral and neural plasticity in fMRI sessions before and after 10 sessions of working memory updating (WMU) training, in which the difficulty of practiced tasks either adaptively increased in response to performance or was fixed.

Diminished dopamine D1 stimulation may contribute to cognitive impairment in Alzheimer's and Parkinson's diseases, schizophrenia, and other neuropsychiatric disorders. However, orthosteric D1 receptor (D1R) agonists produce receptor desensitization and an inverted U-shaped dose-response curve, but positive allosteric modulators (PAMs) do not. We examined the cognitive effects of DETQ, a D1R PAM, in mice genetically modified to express the human D1 receptor ("hD1 mice"). Read More

HIF-1α is a hypoxia-inducible protein that regulates many cellular processes, including neural stem cell maintenance. Previous work demonstrated constitutive stabilization of HIF-1α in neural stem cells (NSCs) of the adult mouse subventricular zone (SVZ) and hippocampal subgranular zone (SGZ). Genetic inactivation of NSC-encoded HIF-1α in the adult SVZ results in gradual loss of NSCs, but whether HIF-1α is required for the maintenance of SGZ hippocampal progenitors and adult hippocampal neurogenesis has not been determined.

Background: Traditional methods to assess pain in rodents depend on measures of nociceptive responses, most commonly from the hind paws. While these measures can quantify nociceptive responses to allow pharmacologic testing, they typically have high inter-experimenter variability and are not time-sensitive enough to correct with neural processes that occur on millisecond scales.
New Method: We have invented a pain detection device that uses changes in skin conductance to measure nocifensive withdrawal responses. Read More

Understanding how cortical activity generates sensory perceptions requires a detailed dissection of the function of cortical layers. Despite our relatively extensive knowledge of their anatomy and wiring, we have a limited grasp of what each layer contributes to cortical computation. We need to develop a theory of cortical function that is rooted solidly in each layer's component cell types and fine circuit architecture and produces predictions that can be validated by specific perturbations.

Increased proinflammatory interleukin-6 (IL-6) levels are associated with acquired long QT-syndrome (LQTS) in patients with systemic inflammation, leading to higher risks for life-threatening polymorphic ventricular tachycardia such as Torsades de Pointes. However, the functional and molecular mechanisms of this association are not known. In most cases of acquired LQTS, the target ion channel is the human ether-á-go-go-related gene (hERG) encoding the rapid component of the delayed rectifier K current, IKr, which plays a critical role in cardiac repolarization.

To understand the contribution of intrinsic membrane properties to the different firing patterns of oxytocin (OT) and vasopressin (VP) neurons in vivo, in vitro studies are needed, where stable intracellular recordings can be made. Combining immunochemistry for OT and VP and intracellular dye injections allows characterization of identified OT and VP neurons, and several differences between the two cell types have emerged. These include a greater transient K current that delays spiking to stimulus onset, and a higher Na current density leading to greater spike amplitude and a more stable spike threshold, in VP neurons.

The mechanisms that underpin the formation, growth and composition of otoliths, the biomineralized stones in the inner ear of fish, are largely unknown, as only a few fish inner ear proteins have been reported. Using a partial transcriptome for the inner ear of black bream (Acanthopagrus butcheri), in conjunction with proteomic data, we discovered hundreds of previously unknown proteins in the otolith. This allowed us to develop hypotheses to explain the mechanisms of inorganic material supply and daily formation of growth bands. Read More

While the role of psychosocial factors in contributing to physical and mental health outcomes is widely recognized, the biomedical model remains dominant. This is due in part to 1) the largely non-mechanistic focus of biopsychosocial research, and 2) the lack of specificity it currently offers in guiding clinicians to focus on social, psychological, and/or biological factors in individual cases.

Signal transduction at vertebrate excitatory synapses involves the rapid activation of AMPA (a-amino-3-hydroxy-5-methyl-4-isoxazole propionate) receptors, glutamate-gated ion channels whose four subunits assemble as a dimer-of-dimers. Technical advances in cryo-electron microscopy brought a slew of full-length structures of AMPA receptors, on their own and in combination with auxiliary subunits.

Background: Most people with bipolar disorder spend a significant percentage of their lifetime experiencing either subsyndromal depressive symptoms or major depressive episodes, which contribute greatly to the high levels of disability and mortality associated with the disorder. Despite the importance of bipolar depression, there are only a small number of recognised treatment options available. Consecutive treatment failures can quickly exhaust these options leading to treatment-resistant bipolar depression (TRBD). Read More

Stroke is the result of blockage or rupture of blood vessels in the brain and is the leading cause of death and disability in the world. Currently only a very limited number of therapeutic approaches are available for treatment of stroke patients, and the vast majority of neuroprotective agents that tested positively in pre-clinical studies failed in clinical trials. In recent years, the clinical value of the use of exosomes for stroke treatment has received widespread attention due their unique characteristics such as low immunogenicity, low toxicity and biodegradability, ability to cross the blood-brain barrier (BBB), and their important role in communication between cells.
