Representations of odor in the piriform cortex.

22 Sep 2009 Olfactory perception is initiated by the recognition of odorants by a large repertoire of receptors in the sensory epithelium. A dispersed pattern of neural activity in the nose is converted into a segregated map in the olfactory bulb. How is this ... Read more...

Dopamine modulation of the in vivo acetylcholine response in the Drosophila mushroom body.

13 Sep 2009 Olfactory sensory information in Drosophila is transmitted through antennal lobe projections to Mushroom Body neurons (Kenyon cells) by means of cholinergic synapses. Application of acetylcholine (ACh) and odors produce significant increases in ... Read more...

Pheromone signal transduction in humans: what can be learned from olfactory loss.

30 Aug 2009 Because humans seem to lack neuronal elements in the vomeronasal organ (VNO), many scientists believe that humans are unable to detect pheromones. This view is challenged by the observations that pheromone-like compounds, 4,16-androstadien-3-one ... Read more...

Technical information about 'Olfactory Pathways'

Definition: Set of nerve fibers conducting impulses from olfactory receptors to the cerebral cortex. It includes the OLFACTORY NERVE; OLFACTORY BULB; olfactory tract, olfactory tubercle, anterior perforated substance, and olfactory cortex. The term rhinencephalon is restricted to structures in the CNS receiving fibers from the olfactory bulb.
