How Does the Brain Smell?
transmembrane domain receptors encoded by a family Sensory stimuli are detected by specialized receptors of more than a thousand genes (Buck and Axel, 1991). in sensory organs, and the signals hence generated flow Convergent lines of evidence strongly suggest that indithrough multiple and interconnectedcenters of the brain vidual olfactory sensory neurons express only 1 or few where they are an...
متن کاملModeling of Brain Structures Responsible for Smell
The sense of smell is an important to both humans and animals. The olfactory system, which senses and processes odors, is one of the oldest and most important parts of the brain. The olfactory bulb aids in discriminating and identifying different odors. Olfaction begins when scents enter the nasal cavities and stimulate over 50 million receptor neurons (Travis, 1999). Specialized receptors reac...
متن کاملCT of the brain in taste and smell dysfunction.
Three hundred fifty-four patients with taste and/or smell disorders were evaluated with computed tomography (CT). The largest group was characterized by head trauma (27%), followed by idiopathic causes (26%), postinfluenza-like hyposmia and hypogeusia (15%), and congenital etiologies (14%). Hyposmia and hypogeusia occurred concomitantly in 21%-45%, the percentage varying according to etiologic ...
متن کاملTo smell the immune system: olfaction, autoimmunity and brain involvement.
Aside from its recognition and warning functions, olfaction serves many purposes in the CNS and remains one of the most important means of communication with the environment. In addition to olfactory tract input, the olfactory bulb also receives and provides input to other brain centers that modify neuronal activity. Research in the field of immunology as well as in various brain illnesses is b...
متن کاملInternal representations of smell in the Drosophila brain.
Recent advances in sensory neuroscience using Drosophila olfaction as a model system have revealed brain maps representing the external world. Once we understand how the brain's built-in capability generates the internal olfactory maps, we can then elaborate how the brain computes and makes decision to elicit complex behaviors. Here, we review current progress in mapping Drosophila olfactory ci...
