Article Synopsis
- Animals can recognize odors in just milliseconds, showcasing fast detection abilities that are challenging for artificial systems to replicate.
- Current artificial olfaction technologies are limited by being slow, bulky, and power-hungry, making them less effective for real-world mobile applications.
- A new miniaturized electronic nose has been developed that mimics animal olfaction capabilities, achieving rapid odor classification and temporal pattern encoding, opening doors for advancements in various fields like environmental monitoring and security.
Article Synopsis
- - Odor transport involves turbulent air currents that create varying concentrations of smells over time, which mice can actually discern based on these temporal patterns.
- - Research using advanced recording techniques has revealed that mitral and tufted cells in the mouse olfactory bulb can detect odor frequency changes up to 20 Hz, with specific cells showing strong connections to these fluctuations.
- - The study found that the relationship between the electrical activity of certain neurons and odor concentrations remains consistent regardless of the smell itself, and changes in the brain's inhibitory signals significantly affect how well these neurons respond to odor frequency variations.
Odours are transported in turbulent plumes, which result in rapid concentration fluctuations that contain rich information about the olfactory scenery, such as the composition and location of an odour source. However, it is unclear whether the mammalian olfactory system can use the underlying temporal structure to extract information about the environment. Here we show that ten-millisecond odour pulse patterns produce distinct responses in olfactory receptor neurons.
