The scent of fear.
In this study we tried to find out if fear can be detected from human body odours. Female subjects wore under-arm axillary pads while watching a terrifying film. Saliva cortisol samples were taken before and after the film presentation as a hormonal measure for the fear response. The fear experience itself was measured by Spielberger's State-Trait Anxiety Inventory. A "neutral" film, shown one ...
متن کاملThe scent of life
A plume of invisible aromas rising from wet grass after a rain shower, the smell of a freshly baked cake, or the hint of a perfume wafting in the air can all evoke strong feelings and memories. Our lives are apparently dominated by the visual sense, but often smells trigger much deeper emotional responses. In fact, olfactory sensations rule much of the behaviour and ecology of a myriad of anima...
متن کاملNeurobiology: Tracking the scent
Olfactory sensory neurons are believed to follow a ‘one-neuron-one-receptor’ rule to properly translate odor signals into the brain. However, the complexity of the olfactory system—which displays continuous neurogenesis, with more than 1,000 olfactory receptor genes expressed in several developmental stages—has limited detailed analyses. Two studies now report the application of single-cell tra...
متن کاملBlood Scent
Blood cell production is tightly regulated by cell-intrinsic mechanisms and environmental factors. The study by Utpal Banerjee and colleagues and colleagues reveals that, in Drosophila, olfactory signals control hematopoietic progenitor maintenance, thus uncovering a physiological link between sensory perception and hematopoietic response to environmental stress.
