Olfactory training in the elderly: impact on olfactory perception, cognition and well-being.

, 2023
International audienceNormal aging is characterized by a global decline in sensory acuity and cognition, including olfactory perception. In France, 30% of people over 60 years old suffer from olfactory deficits, that negatively impact physical and mental

Pregnancy and olfaction: A review

Frontiers in Psychology, 2014
Many women report a heightened sense of smell during pregnancy. Accounts of these anecdotes have existed for over one hundred years, but scientific evidence has been sparse and inconclusive.

Gain Control and Sparse Representations in the Olfactory System of the Locust and Fly [PDF]

, 2010
The giant GABAergic neuron (GGN) is a single, paired, non-spiking neuron that arborizes extensively in the mushroom body (MB) of the locust (Leitch and Laurent, 1996), where it overlaps with the dendrites and the axons of Kenyon cells (KCs).

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.

A hit map-based statistical method to predict best ligands for orphan olfactory receptors: Natural key odorants versus "lock picks"

, 2022
S.85-97Smell is a multidimensional chemical sense. It creates a perception of our odorous environment by integrating the information of a plethora of volatile chemicals with other sensory inputs, emotions and memories.

Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]

, 1999
What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...

Chemosensory Event-Related Potentials and Power Spectrum Could Be a Possible Biomarker in 3M Syndrome Infants?

Brain Sciences, 2020
3M syndrome is a rare disorder that involves the gene cullin-7 (CUL7). CUL7 modulates odour detection, conditions the olfactory response (OR) and plays a role in the development of the olfactory system.

Olfactory Stimulation Modulates Visual Perception Without Training

Frontiers in Neuroscience, 2021
Considerable research shows that olfactory stimulations affect other modalities in high-level cognitive functions such as emotion. However, little known fact is that olfaction modulates low-level perception of other sensory modalities.

Application of artificial intelligence to decode the relationships between smell, olfactory receptors and small molecules

Scientific Reports, 2022
Deciphering the relationship between molecules, olfactory receptors (ORs) and corresponding odors remains a challenging task. It requires a comprehensive identification of ORs responding to a given odorant.

Fast Olfactory Threshold Determination Using an Ascending Limits Procedure

, 2022
S.35-41Introduction: The Sniffin' Sticks test battery is currently considered the best alternative for the measurement of olfactory threshold, discrimination and identification capabilities. These tests still suffer from limitations, however.
