Emotion and Stress Flashcards
A theory proposing that conscious awareness of emotion and the physiological changes accompanying it are produced by parallel and separate mechanisms
Cannon-Bard theory
The Autonomic nervous system consists of what 2 divisions?
Sympathetic and Parasympathetic
Physiological changes that help us to stay alive in a dangerous situation (fight or flight) is part of what nervous system?
sympathetic
A major branch of the autonomic nervous system whose main function is to conserve and restore the body’s resources (ie. reduce arousal)
Parasympathetic nervous system
A group of nuclei located in the anterior (front) part of the medial temporal lobe that forms an important part of the limbic system:
Amygdala
A theory proposing that autonomic physiological changes governed by our autonomic nervous system precede and determine the conscious awareness of an emotion:
James-Lange theory of emotion
A major branch of the ANS whose main function is to mobilise the body’s resources for flight or flight (i.e. increase arousal)
Sympathetic Nervous System
A group of interconnected brain regions that includes an arc of phylogenetically old cortex on the basal surface of the neocortex and several other regions including hippocampus, amygdala, fornix, mammillary bodies, hypothalamus and anterior thalamus:
Limbic system
A monoamine neurotransmitter, also called 5-hydroxytrymptamine (5-HT), which is implicated in a wide range of functions:
Serotonin
The front portion of the cerebral cortex that contains several important anatomical areas including the orbitofrontal and dorsolateral regions, Broca’s area, and primary motor cortex:
Frontal cortex
The abbreviation for gamma aminobutyric acid - an amino acid neurotransmitter that is probably the most common inhibitory substance in the central nervous system:
GABA
What does stimulation of the medial hypothalamus elicit?
aggressive behaviour with strong sympathetic arousal
What part of the brain is known as the ‘emotional centre’?
hypothalamus
When we become aware of our body’s physiological arousal, we seek to understand cognitively what is causing this to happen. We generally attribute our emotion to the prevailing environmental conditions:
Cognitive-arousal theory
What are the seven basic facial expressions for emotion?
Anger, happiness, fear, disgust, surprise, contempt, sadness. (sometimes embarrassment)
What is the facial feedback hypothesis?
We experience emotion in part as a result of the position of our facial muscles.
What part of the amygdala appears to play an important role in the acquisition and storage of memory associated with fear conditioning?
Lateral Nuclei
What is the main output pathway of the amygdala, which includes a major projection to the hypothalamus?
central nucleus
What nervous system is vital for producing behavioural manifestations of fear?
ANS
What controls the ANS
hypothalamus
Part of the brain involved in emotional conditioning and in helping the animal to evaluate the significance of fearful associations with events in its environment:
Lateral amygdala
Philip Bard found that lesions of the cerebral cortex
Produced highly emotional animals and ‘sham’ rage
What are the 3 main groups of nuclei in the amygdala?
Basolateral, Central nucleus and corticomedial amygdala
Removing what parts of the brain reduced fear in rhesus monkeys?
bilateral removal of the temporal lobes, amygdala and parts of hippocampus
