Chapter 8 Flashcards
Sympathetic Nervous System
activates during bodies arousal
- increases physiological symptoms and shuts sown digestion
Emotion
an increase or decrease in physiological activity accompanied by feelings that are characteristic of the emotion
- often accompanied by behaviour or facial expression
Parasympathetic
certain emotions activate this
- shuts down the body following arousal
- rest and digest
- decreases symptoms created by the sympathetic nervous system
James Lange Theory
emotional experience come from physiological arousal that recedes it
- different emotion are result of different patterns of arousal
- emotion comes after the bodies reaction, then the brain tells you why your body is reacting this way
- early research supported this theory
Cognitive Theory
belief that identity of an emotion is based on cognitive assessments of a situation
- emotion is a cognitive choice
- mental and physiological arousal combine to create emotion
- can be mental without physical
- can explain why some people misidentify their emotion
Integrative Embodiment Theory of Emotion
combination of the James Lange Theory and Cognitive Theory
Mirror Neurons
neurons that fire both when we engage in a specific act and while observing the same act in others
- empathy is related to the number of active mirror neurons you have
- first discovered in monkeys
- narcissists wouldn’t have mirror neurons in the emotion system
Limbic System
network of structures arranged around upper brain stem
- central to emotion, motivation, learning, and memory
- emotion processed in hind, mid, and forebrain
Hypothalamus
primary control over the autonomic system
- produces general autonomic activation
- accompanied by feelings of fear, rage, or pleasure, depending on the location of the electrode
Type of brain imaging used for emotion
functional
Amygdala
small limbic system structure near lateral ventricle of temporal lobes
- associated with fear and anxiety
Short SLC6A4 Allele
reduced serotonin and increased fear/anxiety due to hyper-responsive amygdala
Bilateral Amygdala Damage
patients with this do not experience traditional dear responses to external stimuli
- still have internal fear
Insular Cortex
involved in disgust
- cortical projection site for taste
Basal Ganglia
involved in disgust
- involved in motor functions
- plays role I the face made and recognizing the face of disgust on someone else’s faec
- damaged; inability tor recognize disgust on others faces
- OCD and Hutingston; abnormalities basal ganglia
Anterior Cingulate Cortex (ACC)
- attention, decision-making, impulse control
- relates to emotion
- involved in all emotional activity but linked most to stronger emotions like sadness and happiness
Macrophage
ingests invaders and displays foreign antigens
T cells
attracted by specific antigens
- different T cells for different antigens
B cells
produce antibodies that attack a particular cell type
Leukocytes
white blood cells
- recognize invaders by the unique proteins that every cel has on the surface and kills them
