Article Abstract
Olanzapine is an antipsychotic drug applied in psychiatry to treat psychoses, especially schizophrenia and schizoaffective disorders with similar or better improvement than haloperidol and risperidone in the treatment of depressive and negative symptoms. The effect of olanzapine on neural synchrony remains to be explored. We investigated the effects of olanzapine on gamma oscillations in the CA3 region of the hippocampus and frontal association cortex. Olanzapine reduced carbachol (CCh)-induced gamma oscillation power in CA3 slice and gamma oscillation power in the frontal association cortex in vivo. The power of theta oscillations was increased in the presence of olanzapine. The phase amplitude coupling of theta and gamma wave was strengthened by the administration of olanzapine in the frontal association cortex in vivo. Taken together, these results show that olanzapine modulates local field potential and the neuronal activity.

To explore the effect of brain cognitive compensation on the pathogenesis of postoperative delirium (POD) in the frontal glioma patients. Eighty-four adult patients with unilateral frontal glioma who underwent elective craniotomy and 37 healthy controls were recruited. Primary outcomes were POD during postoperative 1-7 days, as assessed by Confusion Assessment Method.

It has been recently described the Congenital Zika Syndrome (CZS). Children from pregnant women who were infected by the virus have expressed a set of symptoms, particularly involving neurological disorders such as microcephaly. Animal models have been conducted aiming to enhance the knowledge about the CZS and giving support for future studies proposing prevention and treatment for this condition.

Sleep neurophysiology undergoes significant changes across the lifespan, which coincide with age-related differences in memory, particularly for emotional information. However, the mechanisms that underlie these effects remain poorly understood. One potential mechanism is the aperiodic component, which reflects "neural noise", differs across age, and is predictive of perceptual and cognitive processes.

The purpose of this study was to compare brain metabolite concentrations between healthy and CHD neonates before and after cardiac surgery. Healthy term newborns and neonates with CHD were recruited prospectively. T-weighted brain images and MRS data were acquired in the cerebellum, right frontal lobe and basal ganglia.

Objective: This multicenter study aimed to investigate resting-state brain functional alterations in patients with type 2 diabetes mellitus (T2DM) comorbid with obstructive sleep apnea (OSA), and to elucidate the underlying neural mechanisms.
Methods: A total of 139 participants were enrolled from two centers, including 48 healthy controls (HCs), 46 T2DM patients, and 45 T2DM with OSA patients. Resting-state functional magnetic resonance imaging (rs-fMRI) was used to assess brain function using degree centrality (DC), amplitude of low-frequency fluctuation (ALFF), and seed-based functional connectivity (FC).
