Nervous System Introduction Teenage brains Nervous System Introduction

Human Behavior and Human Brain Brain Regions Cerebral lobes Cerebellum Limbic System Brain Stem Neurons brain cells Neurotransmitters brain chemicals

Human Behavior and Human Brain Sensory Input Sight Sound Smell/Taste Touch Cognition/Processing Sensory Interpretation Memory Decisions Behavioral Output Motor Response Emotional Response Reflex

Teen (Maturing) Brain Improving Connections More Connections neurons/dendrites Stronger Connections neurotransmitter receptors Faster Connections myelinated neurons/white matter

More Connections Neurons add connections when stimulated… More dendrites, not more neurons

Faster Connections Grey Matter = Unmyelinated = no insulation = slower White Matter = Myelinated = insulation = faster

Stronger Connections More use = more receptor sites “Practice makes permanent”
