1 Nervous System Introduction
Teenage brains Nervous System Introduction

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

3 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

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

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

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

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