2. CB 48.3 Nerves allow us to perceive the environment while the brain integrates the incoming signals to determine an appropriate response.

3. electrical at synapse chemical At the synapse the electrical signal is converted to a chemical signal

4. CB 48.16 Neurons are commonly connected to many other neurons, and the effect of the different incoming signals determines what the neuron will do.

5. CB 48.19 The brain and the central nervous system integrate the various incoming signals

6. The optic nerves for each eye enter opposite sides of the brain CB 49.24

7. CB 48.23 Human Brain Development (don’t copy all of this) : Cerebrum- integration and memory Brainstem- homeostasis and input sensory info Cerebellum- motor functions Diencephalon- input to cerebrum and homeostasis

8. CB 48.24 Input to brain is filtered. What are you paying attention to?

9. CB 48.25 Circadian Rhythms: daily patterns set by light (northern flying squirrel)

10. CB 48.26 Cerebrum: higher brain function

11. CB 48.26 Neocortex: thin layer on outside of the cerebrum. ~5mm thick but ~80% brain mass.

12. CB 48.26 Corpus Callosum: communication between hemispheres

13. CB 48.27 Different regions of the cerebral cortex integrate different inputs/outputs

14. CB 48.29 Visualizing the specialization of brain regions

15. CB 48.28 Some body parts have more sensory input/ motor control

16. CB 48.30 The Limbic System: generating and reacting to emotions
