Host location in a specialist parasitoid wasp via olfactory cues – a physiological, behavioural and morphological study

, 2012
For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned

mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

Advanced Science, EarlyView.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...

Stepwise pathways from the olfactory cortex to central hub regions in the human brain

The human brain is organized as a hierarchical global network. Functional connectivity research reveals that sensory cortices are connected to corresponding association cortices via a series of intermediate nodes linked by synchronous neural activity ...

Senescence-like cells recruit γδ T cells to drive prolonged hyposmia after SARS-CoV-2 infection in mice

EMBO Reports
Persistent hyposmia is a hallmark of post COVID-19 conditions, yet the mechanisms sustaining olfactory dysfunction after viral clearance remain poorly understood.

Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

Advanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

Utilization of RNA sequencing to investigate olfactory dysfunction in chronic rhinosinusitis without nasal polyps: A pilot study

World Journal of Otorhinolaryngology-Head and Neck Surgery
Objectives Prior research on olfactory dysfunction in chronic rhinosinusitis (CRS) has focused on patients with polyps and suggests that direct inflammation of the olfactory cleft mucosa plays a contributory role.

Dynamics and adaptation in the olfactory and phototransduction pathways [PDF]

, 2012
Due to their function of “probes” of external stimuli, sensory systems have to be able to respond appropriately to a wide range of amplitudes of the input signal.

The gustatory system influences "Drosophila" lifespan [PDF]

, 2011
The lifespan of an organism is affected by the complex interplay between genetic and environmental factors. In C. elegans, this interaction between genes and environment is mediated by the sensory system.
