Latest Olfactory receptor neuron Stories
The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents.
Environmental stimuli often trigger our sense of smell before we exhibit any other response. Smells trigger neurons in our brains that alert us to take action, but there is often more than one odor in our environments at any given time.
Fish fail to detect danger in copper-polluted water.
Biologists at the California Institute of Technology (Caltech) have identified the origin of olfactory nerve cells, finding that neural-crest stem cells – multipotent, migratory cells unique to vertebrates that give rise to many structures in the body – play a key role in building olfactory sensory neurons in the nose.
Eating spoiled food can be fatal as it allows bacterial pathogens to enter the digestive system. One of the main tasks of the sense of smell is to detect signs of decay, allowing us and other animals to avoid such food poisoning.
A team of scientists from Johns Hopkins and other institutions report that restoring tiny, hair-like structures to defective cells in the olfactory system of mice is enough to restore a lost sense of smell.
Researchers from the Stowers institute for Medical Research have traced individual odor molecules in the brain to create a new model of how our sense of smell works.
How are 100 billion cells created, each with specific duties?
How are 100 billion cells created, each with specific duties? The human brain is evidence that nature can achieve this. Researchers at Linköping University in Sweden have now taken a step closer to solving this mystery.
Fruit flies don't have noses, but a huge part of their brains is dedicated to processing smells.
