Brain, Nervous System & Emotions
Kimberly NelsonMTHS 2013
Triune Brain Theory Reptilian brain
Limbic (early mammalian) brain
Neocortex (neo-mammalian) brain
Reptilian Brain
Reptilian Brain Also called the brain stem Develops between conception and first 15
months after birth Job: self preservation Monitors outer world through sensory
input Then…activates body for survival 100 trillion nerve nets that link all senses
Reptilian brain, cont. Includes: brain stem, medulla oblongata,
pons & cerebellum Sensations are sent:
Through the brain stem… To the switch board or pons… To the thalamus in the limbic brain… To the neocortex for interpretation
Limbic Brain Links to neocortex allowing for emotional
or cognitive (thinking) processing Works with the body to show physical
signs of emotions, like flush of embarrassment or smile of joy
Determines the release of neuro-transmitters that strengthen or weaken immune system
Limbic brain, cont. 4 major structures of limbic brain
Thalamus: relay station for incoming sensory information,
except smell Relays info from brain to muscles Interprets pain, temp, pressure Connections between emotions & memory
Hypothalamus Pituitary gland Manages: hunger, thirst, temp, sleeping state Mind-over-body phenomena Aggression & pleasure
Limbic brain, cont.Amygdala
Links to brain areas involved with cognitive and sensory processing
Regulates your body state=to emotional state Recognizes facial expression & body language Body reactions to fear or anxiety
Hippocampus Short term memory Transfers info into long term memory
Neocortex Cerebral Cortex Outer gray layer of brain, 80% of brain Controls motor movement Communication: language, process visual
information, speech Problem solving & processing ideas

What does this all mean? What are some connections you can make
about this information and what you already know about emotions?
From observation to responseDuring our day, we experience events that
cause emotional responses. What steps does our body/brain take to process and act towards a response?
Observation to responseWhat influences could effect our response?
Consider: Observation skills and abilities History: past events, info, prejudge State of brain: nutrition, sleep, water Mental state: stress, sickness Brain’s ability to communication (synapse
development) Age, developmental state Brain’s communication style & experiences Fight or flight, phobias, abuse Mental health
There’s a spider in my bed!!! Identify:
How does the information get into your brain? What does your limbic system do? To react to the spider, what will the following parts do:
Thalamus (sees the spider)
Hypothalamus (connects an emotion to seeing it)
Amygdala (body reacts to fear)
hippocampus (takes from short term memory to long term memory)
Feelings & Needs All humans have needs Areas of needs
Self-expression: create, play Autonomy: goals, dreams, choices Interdependence: acceptance, respect Spiritual: joy, meaning Physical: basic needs, protection, sexual Where have you seen this before?
Practice getting what you need Situation
What did you see? What did you feel? What do you need? How would you do or request?
Connection What is the connection between emotions
and getting your needs met?
