James Lange
Stimulus –> autonomic –> conscious feeling
arousal

Common sense
Stimulus –> conscious feeling –> autonomic arousal
Cannon-Bard

brain activity –> autonomic arousal
First the brain and then the rest of body reacts
Schachter
Stimulus –> autonomic arousal –> appraisal–> conscious feeling
Think of and appraise th physical feeling to get consious feeling
Cingulate Gyrus
Front part, anterior cingulate cortex (ACC)
Central hub for emotional awareness, self monitoring and decision making
Limbic system
Cortex in the limbic system –> ALLOCORTEX
evolutionary older and consists of 4 layers of neurons
Critical structures
Emotional and motivated behavior
Hypothalamus & associated pituitary gland
Information to the brainstem to produce behavior involved in hormonal system
Limbic and reward system Both project to
Frontal lobes the hypothalamus
Innate releasing mechanism (IRM)
Fixed action pattern (FAP)
Mechanisms that detect specific sensory stimuli & direct organism to take particular action
Can be modified by experience
Ventral striatum/ Nucleus accumbens (NACC)
Part of reward system responsible for attraction, desire, goal-oriented action, reward and learning
Hypothalamus ANS
Prefrontal cortex: Long term goals
Limbic system: Short term goals
Regulatory behavior
Motivated behavior to meet the survival needs of the animal
Controlled by homeostatic mechanisms (hypothalamus)
Internal body temperature, eating, dinrking, salt consumption and waste elimination
Based on feedack loop system
Nonregulatory behavior
Unnecassary behavior to meet basic survival needs
Frontal lobes more involved then hypothalamus
Strongly influenced by external stimuli
For example: Sex, parenal instinct, agression, food preference, curiosity and reading
Motivation
Motivated behavior is behavior taht is purposeful and goal directed
BUT
not always in line with long term goals
