Introduction: Specific features of subjective cognitive decline (SCD-plus) have been proposed to indicate an increased risk of preclinical Alzheimer's disease (AD). However, few studies have examined how these features relate to AD biomarkers in cognitively unimpaired (CU) older adults.
Methods: Meta-analyses were performed using cross-sectional data from nine cohorts (n = 7219, mean age (SD): 71.
Article Synopsis
- * This study focuses on the olfactory system, looking at how neurons in this area may communicate through a special region called a "communication subspace."
- * The findings show that these neuronal groups in the olfactory pathway communicate based on breathing patterns and can send information back and forth, with the effectiveness of this communication affected by anesthesia.
Anxiety elicits various physiological responses, including changes in the respiratory rate and neuronal activity within specific brain regions such as the medial prefrontal cortex (mPFC). Previous research suggests that the olfactory bulb (OB) modulates the mPFC through respiration-coupled oscillations (RCOs), which have been linked to fear-related freezing behavior. Nevertheless, the impact of breathing on frontal brain networks during other negative emotional responses, such as anxiety-related states characterized by higher breathing rates, remains unclear.

At subanesthetic doses, ketamine induces transient psychosis in humans, and is used to model psychosis in experimental animals. In rodents, subanesthetic doses of ketamine increase the power of high-frequency oscillations (HFO, > 100 Hz) in the electroencephalogram (EEG), a frequency band linked to cognitive functions.
