parts of the papez circuit actually involved in emotions
cingulate cortex and the hypothalamus
Areas of the limbic system involved in emotional processing
amygdala, anterior and mid-cingulate cortex, mediodorsal nucleus of the thalamus and prefrontal cortex.
Primary emotions are reflexive and involve the (3)
amygdala, hypothalamus, and PAG
what primarily drives primary emotions?
the amygdala ---- which gets input from the auditory pathway (or visual) via the thalamus as well as directly from the auditory pathway.
___ emotions are conscious
secondary emotions and involve the ___
cortical limbic structures
Stimulation of the___ with norepinephrine induces the fight or flight response
dorsolateral portion of the PAG
. Stimulation of the ___ portion of PAG with norepinephrine leads to hypoactivity
Since the ___ nuclei project to the PAG, you can also stimulate the ___ nuclei for the same effect.
You need the ___ and ___ to regulate emotions.
If you get a stroke or tumor to either one of these regions you lose control of your emotions and can result in sham rage (excessive rage without external control)
hypothalamus or the PAG
. Only th___ and ___ cingulate cortex play a role in emotional processing.
is the posterior cingualte cortex ivnovled in emotion?
. It may be useful to think of serotonin as mood ___
. It may be useful to think of norepinpehrine as mood
what is included in the papez circuit
___ is the synapse site of the limbic system in the thalamus
primary emotions are linked with ___ reflexes
If a monkey’s temporal lobe / amygdala was removed, the animal became (4)
4. and ate inappropriate items.
Urbach-Wiethe disease = what is the cause and what are the sx?
calcification & loss of amygdala
1. no fear response
2. can’t recognize fear in faces
3. risky behaviors
Fear response involves direct connections from
thalamus to amygdala
Shown by auditory-foot shock conditioning experiment. Even if amygdala/
auditory cortex connection was cut,
fear was still present
Amygdala connects to __ and __ for fight-or-flight response
PAG and LC
Stimulation of ___ PAG = fight-or-flight,
lesion of Dorsal PAG
affective defense & "sham rage"
lesion fo ventral pag
All major emotion structures are connected to
The PAG regulates ANS via
dorsal mtoor fo vagus
The hypothalamus-pituitary axis (HPA) is driven by the (3)
amygdala, limbic cortex, & locus
Amygdala / Insula / Limbic Cortex (ACC) --> Paraventricular Nucleus (PVN) of hypothalamus -->
the amygdala projects to which cingulate cortex?
the ACC and anterior MCC
