Circuit dynamics of the olfactory pathway during olfactory learning

Frontiers in Neural Circuits
The olfactory system plays crucial roles in perceiving and interacting with their surroundings. Previous studies have deciphered basic odor perceptions, but how information processing in the olfactory system is associated with learning and memory is poorly understood. In this review, we summarize recent studies on the anatomy and functional dynamics of

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Physiopathology of nasal and ecnomotopic olfactory receptors: focus on molecular pathways and potential pharmacological modulation

Frontiers in Pharmacology
Detection and discrimination of chemosensory stimuli (usually known as odorants) by the olfactory system exert a crucial role in animal survival. Olfactory receptors (ORs) are a large family of G protein-coupled receptors (GPCRs) mainly expressed by the ...

The olfactory limbus of the red fox (Vulpes vulpes). New insights regarding a noncanonical olfactory bulb pathway

Frontiers in Neuroanatomy, 2023
Introduction: The olfactory system in most mammals is divided into several subsystems based on the anatomical locations of the neuroreceptor cells involved and the receptor families that are expressed.

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

The signal-transduction pathways of the peripheral olfactory organ and their impairment in vertebrates

Aquaculture and Fisheries
Animals rely on olfaction to detect and process invaluable chemical information about their environment. For olfaction to function, chemicals must first be detected, which leads to the activation of signal-transduction pathways at the peripheral ...
