Sensation and Perception
Two Inseparable Processes
• Physical Sense
• experience not required
o reception (eavesdrops something in the environment)
o transduction (transformed into neural messages via axons into neurons
o transmission (info given to brain to be revealed)
• Mental interpretation
• Experience required
We have the least sensitive nose in the animal kingdom. It was the first sense known.
It’s the most direct link between environment to brain.
o Deciphers between audio/visual
o Smell does not go to the thalamus
