1. Parts/lobes of the brain
Bullet 1
MT: Nervous system 1

2. 4 Lobes of the Brain
Frontal
Parietal
Temporal
Occipital

3. Frontal Lobe
Fxns: reasoning, planning, problem solving, logics, thinking
Biggest area of brain
Stops developing ~25 years old

4. Parietal Lobe
Fxns: recognizing stimuli, orientation, and recognition

5. Temporal Lobe
Fxns: memory, speech, and auditory stimuli

6. Occipital Lobe
Fxns: visual processing

7. Important Lines of Brain
Central Sulcus: separates frontal and parietal lobes

8. Important Lines of Brain
Lateral fissure: separates temporal and frontal lobes

9. Important Lines of Brain
Longitudinal fissure: separates brain medially

10. INSIDE OF Brain

11. Parts of the Brain
Brainstem (old reptilian brain) = midbrain, pons, and medulla oblongata
Limbic System (old mammalian brain) = thalamus, hypothalamus, amygdala, hippocampus
Corpus Callosum

12. Brainstem: Midbrain, Pons, Medulla Oblongata

13. Brainstem: Midbrain: -superior end of brainstem
-Fxn: eye mvmts, reflexes in pupil
Pons:
-inbetween midbrain and medulla
-Fxn: regulates respiration (breathing)
Medulla Oblongata:
-inferior end of brainstem; leads into spinal cord
-Fxn: heart rate, vomiting, coughing, sneezing, hiccupping, swallowing

14. Parts of the Brain
Brainstem (old reptilian brain) = midbrain, pons, and medulla oblongata
Limbic System (old mammalian brain) = thalamus, hypothalamus, amygdala, hippocampus
Corpus Callosum

15. Limbic System Thalamus:
-Fxn: relay center; most sensory neurons go here and then they are sent to correct place
Hypothalamus:
-Fxn: controls sleep/wake cycles, homeostasis, thirst, appetite
Hippocampus:
-Fxn: memory and learning
Amygdala:
-Fxn: memory of emotional situations especially fear

16. Limbic System

17. Parts of the Brain
Brainstem (old reptilian brain) = midbrain, pons, and medulla oblongata
Limbic System (old mammalian brain) = thalamus, hypothalamus, amygdala, hippocampus
Corpus Callosum

18. Corpus Callosum Corpus Callosum:
-Fxn: neurons cross to other side of brain
Ex: left eye sends signal through left hemisphere, through the corpus callosum, to the right hemisphere, to the occipital lobe

20. Taking sides…. how the two sides process information that is!
Left Brain
Logical
Sequential
Rational
Analytical
Objective
Looks at parts
Right Brain
Random
Intuitive
Holistic
Synthesizing
Subjective
Looks at wholes

21. Left Hemisphere processes things more in parts and sequentially
recognizes positive emotions
Identified with practicality and rationality
Understands symbols and representations
Processes rapid auditory information faster than the right (crucial for separating the sounds of speech into distinct units for comprehension)
is responsible for language development. It develops slower in boys, that is why males usually develop more language problems than females.

22. Right Hemisphere
Recognizes negative emotions
High level mathematicians, problem solvers, and chess players use
The “non-verbal” side
Responds to touch and music (sensory)
Intuitive
Responsive to color and shape
Emotional and originative

23. Taking sides…. what information the two sides recognize!
Left Brain
Letters
Numbers
Words
Right Brain
Faces
Places
Objects
based on Sousa (1995, p. 88)

24. Taking sides….take the test!
Hemispheric Dominance Inventory Test

25. Myth of “Right/Left brained”
