DID YOU HEAR THAT?
Auditory Process: Perceiving Pitch
Place Theory: Links the pitch we hear with the place that is stimulated in the cochlea
Frequency Theory: Measures neural impulses travelling the auditory nerve.
DID YOU HEAR THAT?Volunteer Time!!
Auditory Localization The brain calculates a sound’s
location by using these differences. Timing (.000027sec. Diff) Sound travels @ 750 mph
Sound Waves Loudness (amplitude) Pitch (frequency)
Long waves; low frequency/low pitch
Short waves; high frequency/high pitch
Taste Buds Photograph of tongue
surface (top), magnified 75 times.
10,000 taste buds line the tongue and mouth. Taste receptors are
down inside the “bud”
Children have more taste buds than adults.
Sensory Integration Different sensory modalities exist because
signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain.
Synesthesia A condition in which stimulation of one sense
also evokes another.
Starburst time!! Conduct the experiment and answer the
following questions with your partner. What factors influence taste? What are the 5 basic tastes? What is sensory interaction? How do we experience smell? Use pages 146-150 to help answer the
questions.
Different Tastes Different people have different tastes based
on: Genetics Culture Learning Food attractiveness
Smell: The Sense of Scents
Airborne chemical molecules enter the nose and circulate through the nasal cavity. Vapors can also enter through the mouth and pass into
nasal cavity. Receptors on the roof of the nasal cavity detect these
molecules.
Olfactory System
