Are emotions learned or innate? - ANSWER-A number of different experiments suggest
that neurons in the amygdala can "learn" to respond to stimuli associated with pain, and
after such learning, these stimuli evoke a fearful response.
In the Papez circuit is the direction between the cortex and and hypothalamus
bidirectional? is it compatible with both James-Lange and Cannon-Bards' theories of
emotion? - ANSWER-Yes
What are the criticisms of a SINGLE emotional system concept? - ANSWER-1) While
experiments point to certain structures within Broca's limbic lobe and the Papez circuit
being involved in emotion processing, some, like the hippocampus a component in the
Papez system, are no longer believed to be essential for expressing emotions
2) Although the term limbic system is still commonly used in discussions of brain
mechanisms of emotion, it has become increasingly clear that there is not a single,
discrete eYes
) While experiments point to certain structures within Broca's limbic lobe and the Papez
circuit being involved in emotion processing, some, like the hippocampus a component
in the Papez system, are no longer believed to be essential for expressing emotions
motion system.
3) Solid evidence indicates that some structures involved in emotion are also involved in
other functions; there is not a 1 to 1 relationship. between structure and function in this
case; as brain parts of the brain involved in emotions are also used for other things.
There's no simple match-up between brain parts and their jobs.
Describe Klüver-Bucy Syndrome - ANSWER-Yes

Kluver-Bucy syndrome results from bilateral lesions of medial temporal cortex, including
the amygdala and parts of he hippocampus. Deficits are a loss of understanding of
emotional significance of objects- emotional blunting, impaired object recognition,
hypersexual behavior.
Bilaterally removing the temporal lobes in rhesus monkeys significantly diminishes their
aggression and fear responses. In other words, normal experience and the normal
expression of fear and aggression were severely decreased by the temporal lobectomy.
What does the Klüver-Bucy syndrome tell us about where in the brain emotions are
processed? - ANSWER-1) The amygdala is critical for fear and aggression
2) The temporal lobes are involved in emotional arousal
3.) The temporal lobes contribute to emotional memory
4) The temporal lobes are important for social and emotional processing:
What is the effect of Klüver-Bucy Syndrome in humans...? - ANSWER-Humans with
temporal lobe lesions, exhibit symptoms of Klüver-Bucy syndrome, including flattened
emotions, that is decreased vocalizations and facial expressions (flat affect), similar in
the rhesus monkeys.
What are the amygdala's inputs (afferents) and outputs (projections)? - ANSWER-
Inputs: source of afferent; neocortex in all lobes of the brain, as well as the hippocampal
and cingulate gyri.
Outputs: Two major pathways that connect the amygdala with the hypothalamus are the
ventral amygdalofugal pathway and the stria terminalis.
What is the "Unconscious Emotion" theory and what theory does it support? -
ANSWER-James-Lange Theory,
Subjects showed autonomic and amygdala responses to subliminal angry faces, despite
no conscious perception of the faces. This observation supports the concept of
unconscious emotions.
How is Unconscious Emotion revealed? (How is it studied in the lab) - ANSWER-
Despite not consciously perceiving the angry face, the amygdala showed increased
activity. PET recorded brain activity while photos were presented, revealing the brain's
unconscious processing of previously conditioned stimuli.
