Today’s Agenda:

The Brain
HW:
Learning Outcomes (best have it printed…)
CRA (by Monday)

2. HOW DOES OUR BIOLOGY AFFECT OUR BEHAVIOR?
Learning Outcome: Outline principles that define the biological level of analysis.
HOW DOES OUR BIOLOGY AFFECT OUR BEHAVIOR?

3. The nervous system is divided into the
peripheral nervous system (PNS) and the
central nervous system (CNS)
THE NERVOUS SYSTEM

4. The PNS consists of The CNS consists of the
sensory neurons running from stimulus receptors that inform the CNS of the stimuli
motor neurons running from the CNS to the muscles and glands - called effectors - that take action.
The CNS consists of the
spinal cord
brain

5. Central
Nervous System
(CNS):
Spinal Cord &
Brain

6. CNS: controls behavior & coordinates movement between/among all different parts of the body
Brain protected by the skull, spinal cord protected by vertebrae/ spinal column but this does NOT mean they are safe from injuries

7. Is fight or flight response a reflex?
What is a reflex?
it can occur without going through the brain to process.
an automatic (otherwise called involuntary) neuromuscular action elicited by a defined stimulus.
Is fight or flight response a reflex?
Yes: according to what criteria?
No: according to what criteria?

8. THE BRAIN: most important part of life…

9. Our brain has 4 lobes Frontal (Freud) Parietal (his Pants)
Frontal (Freud)
Parietal (his Pants)
Occipital (Off)
Temporal (Tore)
Cerebellum
Brain Stem

10. Frontal Lobe- Parietal Lobe- Occipital Lobe- Temporal Lobe-
reasoning, planning, parts of speech, movement, emotions, and problem solving
Parietal Lobe-
movement, orientation, recognition, perception of stimuli
Occipital Lobe-
visual processing
Temporal Lobe-
perception and recognition of auditory stimuli, memory, and speech
4 Lobes

11. HEMISPHERES
Our brain has 2 hemispheres: a LEFT and a RIGHT. Our LEFT controls the RIGHT side of our body, and vice-versa.

12. HEMISPHERES

13. Our Brain’s Main Structures
2 hemispheres, 4 lobes…but there’s more:
Cerebellum
"little brain", is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex.
This structure is associated with regulation and coordination of movement, posture, and balance.
Our Brain’s Main Structures
Brainstem
vital life functions such as breathing, heartbeat, and blood pressure
Medulla, pons, midbrain
Limbic System
referred to as the "emotional brain", is found buried within the cerebrum. Like the cerebellum, evolutionarily the structure is rather old

15. ALL OF THIS DEPENDS ON…

16. NEURONS

17. A specialized cell transmitting nerve impulses; a nerve cell
