Schachter's theory on peripheral feedback
peripheral feedback affects emotional intensity, but perceptions and thoughts determine the
type of emotion
Ekman's theory on peripheral feedback
feedback from facial muscles can induce feelings and bodily reactions indicative of emotion
The amygdala rapidly evaluates sensory information for ________
its significance to survival or well-being and triggers bodily responses
The Prefrontal Cortex
crucial for conscious emotional experience and deliberate action based on it
Right prefrontal cortex responsible for ________
Left prefrontal cortex responsible for __________
right : withdrawal
left : approach
Smelling
Olfactory bulb sends information to Limbic System after receptor cells are activated. Olfactory
System is optimized for motivation, memory, and emotion
Glomeruli in smelling
relays information to other parts of the brain. can be thought of as a warehouse
Mitral Cells in smelling
can be thought of as shipping drones. these cells are relaying the information that the glomeruli
has sent
The Obritofrontal Cortex in the temporal lobe
responsible for identification
Orthonasal Olfaction versus Retronasal Olfaction
a- what your nose detects from sniffing something that exists in the world
b- creates flavor from smell molecules in foods or drinks shunting up through the nasal
passages as one is chewing
Gustatory Pathway
Glossopharyngeal Nerve > in Medulla Oblongata > Thalamus > Gustatory Cortex
Taste Buds are associated with two structures
a- fungiform b- villate papillae
Pain is a body sense. This is otherwise called:
Somatosensation
We experience pain in two waves. Slow pain is known as __________ and fast pain is known
as ______-
slow : C fibers (dull or throbbing pain, more diffuse experience)
fast : A delta fibers (myelinated, sharp localized pain)
Gate Control Theory of Pain
Pressure sensors inhibit A delta fibers. A delta and C fibers send information to > pain
transmission neurons in the spinal cord > brain > sends facilitatory and inhibitory messages to
pain transmission neurons
Pain Inhibitory Messages
