Emotions as Response Patterns
Lateral Nucleus; Basal Nucleus; Central Nucleus
When does the prefrontal cortex mature in relation to the amygdala?
Matures much later
(during late childhood and early adulthood)
______ hemisphere plays more significant role for expressing emotions
Right
What begins the onset of puberty
Onset of puberty beings when cells in hypothalamus release GnRH
Where does information from the lateral nucleus go to?
Ventromedial prefrontal cortex; ventral striatum, dorsomedial nucleus of thalamus; central nucleus; basal nucleus
How would you assess for severe TBI?
WAIS (coding/symbol search)
Rey Osterrieth Complex figure test (working memory)
Long-term memory - ask them something from a week ago
Whats the difference between volitional facial paresis and emotional facial paresis?
volitional facial paresis - can express emotional smiles but can not form a smile when asked
emotional facial paresis - can form a smile when instructed but can not express emotional smiles
Where does Oxytocin go during sexual maturation (think of the picture on slide 22)
uterine muscles; Mammary glands
Activity of serotonergic synapses _______ aggression
inhibits
What are the long-term implications for "Mild" TBI?
increased number and severity of injuries
What is the James-Lange Theory of Emotion?
slide 17 review slides for graphical representation (week 5)
- event that produces emotional reaction -> brain (feedback produces feelings of emotion)
Where does ADH go during sexual maturation (think slide 22)
Kidney tubules
inputs from dorsomedial thalamus, temporal cortex, ventral tegmental area, olfactory system, amgydala (this gives info about _________)
what is happening in environment and what plans are made by rest of frontal lobes
What's the difference between an open head injury vs. a closed head injury?
Open head injury (penetrating head injury) - fractured skull, damage to blood vessels can impair brain blood supply, accumulation of blood can lead to pressure on the brain
CLosed head in jury - coup and contre-coup injuries, torn axons, rupture blood vessels, CSD buildup in ventricles
A single, first dose of fluxotenine (vs. placebo) had an impact on neural response to anger cues (in fMRI) in adolescents w MDD
- reduced activity in amygdala-hippocampal region and inc activity in the dorsal anterior cingular cortexFluoxetine has immediate neural effect on cortico-limbic circuitry prior to clinical changes in mood
What are the effects of pheromones?
chemical released by one animal that affects behavior or physiological of another animal; usually smelled or tasted
hint; what does this do?
Outputspermit it to affect variety of behaviors and physiological responses
What did Badura-Brack et al. 2018 find in their research with veterans with PTSD?
Veterans w PTSD exhibited stronger oscillatory response in the left amygdala (relative to those without PTSD) while viewing threatening faces
No group differences when observing neutral faces
conclusions: amygdala hyper-response to threats begins quickly in PTSD, suggesting a bottom-up fear response

Peptides ______ and _____ may be involved in monogamous relationships
Vasopressin; Oxytocin
