What is the difference between emotions and moods?
Emotions are short-lived states that include the physiological changes for an action.
Moods are persistent states that change the threshold of the organism for emotional
events. Both emotions and moods can be adaptive or maladaptive.
What does bilateral amygdalectomy lead to?
Reduced fear and aggression in animals.
What is septal rage? Why does it happen?
Extremes of emotion and explosive violence caused by lesions of the septum, which
leads to disinhibition of the hypothalamus.
What is Klüver-Bucy syndrome?
This is a temporal lobe malformation that leads to decreased fear, aggression,
vocalization, and facial expressions, likely related to the destruction of the amygdala.
What is Broca's limbic lobe? What structures make it up, where in the brain are
they, and what is its function?
This is an emotional system on the medial wall of the brain that links the cortex with the
hypothalamus. The sructures in it form a ring around the corpus callosum and are
comprised of the cingulate gyrus, medial surface of the temporal lobe, and the
hippocampus.
What are important neuromodulators released during fear? What is their
function?
Fear neuromodulators include stress hormones (e.g. CRH, ACTH, cortisol) and
neurotransmitters (Glu, NE, ACh, DA) released during fear responses. They can
facilitate learning and strengthen associations.
What are the roles of glutamate in fear response?
It is the primary NT driving expression. It is also important for the consolidation and
extinction of fear conditioning, which uses glutamatergic NMDA/AMPA mediated LTP.
What are the roles of GABA in fear response?
, It tightly regulates fear expression.
What structures make up the basolateral complex of the amygdala?
lateral (LA) + basal (B) + accessory basal (AB) nuclei
What are the functions of the lateral amygdala?
-responsive to painful stimuli
-receive visual and auditory stimuli
-critical for emotional responding to shock
-necessary for both cued and contextual fear conditioning
What do lesions to the hippocampal formation affect and not affect in terms of
learning and conditioning?
Lesions don't affect emotional response to shock and only selectively impair contextual
fear learning and don't affect cued fear conditioning.
What is the role of the thalamus in fear conditioning?
Cue-elicited fear in fear conditioning is mediated by strengthening the thalamus<>LA
connection. The response from the thalamus is faster than cortical processing.
What is the role of glutamatergic NMDA receptors in fear? What does blocking
them in the lateral amygdala lead to?
Glutamatergic NMDA receptors are important for LTP needed for fear conditioning.
Activation of these receptors leads to gene activation and then protein synthesis that
allows for the formation of new memories. Blocking NMDA receptors in the LA prevents
cue-elicited fear conditioning.
Where do the basal and accessory basal amygdala get projections from?
They receive projections from CA1 and the subiculum of the hippocampal formation
(HF).
What are the two distinct excitatory cell populations in the B and AB nuclei of the
amygdala? What is the role of each population, and where do they connect?
-anterior "aversion" neurons: respond to negative valence stimuli and have reciprocal
connections w/PL (prelimbic) cortex in the PFC
-posterior "reward" neurons: respond to positive valence stimuli and have reciprocal
connections w/IL (infralimbic) cortex in PFC
What is extinction of fear? It is associated w/increased or decreased inhibition of
which parts of the brain?
Extinction of fear is a competitive "reward" memory and is associated w/increased
inhibition of anterior and decreased inhibition of posterior neurons.
What are the subregions of the central nucleus (CEA) of the amygdala?
lateral central nucleus (CEI) + medial central nucleus (CEm)
What are the roles of the lateral central nucleus (CEI) of the amygdala?
It is similar to the LA. NMDA antagonism blocks acquisition of fear conditioning as
preventing protein synthesis blocks consolidation. Hcc and cereberal cortex inputs are
also involved in context-mediated extinction of cue-elicited fear.
What is the function of the medial central nucleus (CEm) of the amygdala?
It's the primary output for behavioral responding.
What does the central nucleus of the amygdala (CEA) receive input from? What is
its function? What happens when it's lesioned?
