Through the hypothalamus the brain has access to what?
ANS
The brain’s connection to the ANS allows?
Physiological responses that our emotions produce
What is a critical trigger for the experience of emotion?
Smell
The anterior nucleus of the thalamus and the hippocampus are a part of?
Papez circuit
What part of the basal ganglia is particularly involved in emotion?
1) Nucleus accumbens
2) Putamen
In regards to the Papez circuit, what are strongly linked?
Memory and emotion
The more emotional an event was the more likely?
You remember it
Parahippocampal regions are linked to?
Surprise
The amygdala plays a specific role in?
Fear and anger
In terms of layers, the cingulate cortex is mostly?
Paleocortex (3 cell layers)
As you get closer to the frontal cortex, some parts of the cingulate cortex have how many layers?
6
What is an important feature of the cingulate cortex neurons?
They show after-discharge
What is after-discharge?
Neurons continue to fire after whatever event it was that started their firing
What does after-discharge explain?
The lingering effect of emotions well after they have happened. For example, being sad days after the event that caused it
What part of the limbic system is used to create physiologic responses to emotion?
