Neuroscience of Taste and Smell

Recognition of Complex Tastes

• Recognition occurs via parallel neuronal tracts that relay information to cerebral areas, which process distinct tastes independently.
• Neuronal integration operates at various brain hierarchy levels, coding specific patterns interpreted as unique tastes.
• Complex tastes are communicated to the cortex through parallel neuronal tracts responsible for taste interpretation.

Odorant Receptor Proteins (ORPs)

• Among the 350-1200 genes coding for ORPs, only one is expressed in each odorant receptor neuron, allowing each ORP to bind with multiple odorants.
• Alternative scenarios suggest the possibility of either all ORPs being expressed within each neuron or binding restrictions to single odorants, but these do not hold true.
• The specificity of ORP expression and binding is crucial for odor recognition and processing in the olfactory system.
