1. Sub cortical Brain Structures

2. Sub cortical - underneath the cortex –hypothalamus and pituitary –basal ganglia –limbic system –hindbrain and brainstem structures

3. Hindbrain Structures Cerebellum Brainstem –medulla –reticular formation –pons

5. The Parts of the Central Core Medulla- Regulates involuntary breathing and heart rate

6. Cerebellum Small protrusion above medulla Function- Coordinates the smooth movement of muscle

7. The Reticular System The reticular system filters sensory information to determine conscious perception Malfunction has been linked to autism

8. Hypothalamus Contains nuclei involved in a variety of behaviors – sexual behavior –hunger, thirst –sleep –water and salt balance –body temperature regulation –circadian rhythms –role in hormone secretion

9. Hypothalamus and Hormones Hypothalamus releases hormones or releasing factors which in turn cause pituitary gland to release its hormones

10. Hypothalamus video Hunger and the Hypothalamus ( past essay question) Rat study and reward deficiency syndrome

11. Thalamus Thalamus directs sensory info from the touch receptors to the cerebrum. It regulates sleep & wakefulness.

12. Amygdala Inputs come from all senses Amygdala ‘reads’ emotional significance of inputs Output influences such functions as heart rate, adrenaline release

13. Amygdala and Emotion Identify emotion from facial expressions z Amygdala damage makes this task difficult

14. Hippocampus Important in forming new memories Case of Jeremy ( short video)
