Reward + Motivation
Motivational state or drive: internal condition that orients an individual towards a
certain goal
Motivational Drives: hunger drive, thirst drive, thermoregulatory drive, knowledge
drive, many other drives
Religious fasting: practiced by all the major religions, health benefits, why is it linked
to spiritual practices?
Motivational Drives: goal-directed behaviors-incentives, reinforcers, rewards
5 Mammalian Motivational Drives: regulatory drives, non regulatory drives, safety
drives, reproduction drives, social drives, educative drives
Motivational Drives: how are these drives represented in the brain, central drive
system-> hypothalamus (arcuate nucleus: appetite-stimulating neurons,
appetite-suppressing neurons) Use slow-acting neurotransmitters, work over long
periods of times
Leptin: Satiation, Ghrelin: hunger
Sensory Specific Satiety
: ya eat when the good kush is available
Coolidge Effect: sensory specific satiety->for sex
Rewards
Wanting: appetitive behavior; desire->to obtain a reward
Living=Consummatory Behavior; subject feeling of pleasure or satisfaction
Reinforcement: effect on the reward on learning
IntraCranial Self-Stimulation (ICSS)

●Animals specializes in different sensory perception depending on their way of living
●The five senses
○Proprioception – way of perceiving body parts
○Vestibular/ gravity – balance
●General Sensory Process
○Physical stimulus
■Vibration in air
○Physiological response
○Sensory experience
●Olfaction
●What good is sensation
○Literal representation of what is out in environment
●What is scent?
○The actual stuff in air we are perceiving
●Take a vial and take a sniff
Document Summary
Motivational state or drive: internal condition that orients an individual towards a certain goal. Motivational drives: hunger drive, thirst drive, thermoregulatory drive, knowledge drive, many other drives. 5 mammalian motivational drives: regulatory drives, non regulatory drives, safety drives, reproduction drives, social drives, educative drives. Motivational drives: how are these drives represented in the brain, central drive system-> hypothalamus (arcuate nucleus: appetite-stimulating neurons, appetite-suppressing neurons) use slow-acting neurotransmitters, work over long periods of times. Sensory specific satiety : ya eat when the good kush is available. Living=consummatory behavior; subject feeling of pleasure or satisfaction. Animals specializes in different sensory perception depending on their way of living. Proprioception way of perceiving body parts. Literal representation of what is out in environment. The actual stuff in air we are perceiving. Take a vial and take a sniff. Act as a chemical stimulus to the olfactory receptor. Binding to receptors on vili and then triggers an action potential (tickle)
