The stress response in the brain is not fully understood, although stress is one of the risk
factors for developing mental disorders. On the other hand, the stimulation of the olfactory …

Chronic stress has detrimental effects on brain structures and functions. Previous studies
mainly focused on prefrontal cortex and hippocampus, given their well-described roles in …

For most animal species, olfaction plays a paramount role in their perception of the
environment. Odours are initially detected in neurons located in the olfactory mucosa. This …

Effects of smells on stress have been demonstrated in animals and humans, suggesting that
inhaling certain odorants may counteract the negative effects of stress. Because stress plays …

Experiencing chronic stress significantly increases the risk for depression. Depression is a
complex disorder with varied symptoms across patients. However, feeling of sadness and …

In the present study, on rats, a quantitative analysis of Fos protein immunohistochemistry
was performed as a way of investigating the effects of inhalation of green odor (a mixture of …

Links between olfactory sensory function and effect have been well established. A robust
literature exists in both humans and animals showing that disrupting olfaction sensory …

In stressed animals, several brain regions (eg, hypothalamic paraventricular nucleus [PVN])
exhibit neuronal activation, which increases plasma adrenocorticotropic hormone (ACTH) …

Some components of the neural circuits underlying innate odor-evoked responses have
recently been elucidated. Odor information detected by the olfactory receptors is transmitted …

In folk medicine, it has long been believed that odorous compounds derived from plant
extracts can have anxiolytic effects. Among them, linalool, one of the terpene alcohols in …
