3. History of Mind Phrenology
In 1800, Franz Gall suggested that bumps of the skull represented mental abilities. His theory, though incorrect, nevertheless proposed that different mental abilities were modular.

4. Phineas Gage
In 1848, Phineas Gage, a railroad worker was packing gunpower into a rock with a tamping iron.
A spark ignited the gunpowder, shooting the rod up through his left cheek and out the top of his skull, leaving his frontal lobes massively damaged.
To everyone’s amazement, Gage was immediately able to sit up and speak. Although his mental abilities and memories were intact, his personality was not. The soft spoken Gage was now irritable, profane and dishonest. Gage was no longer Gage.

8. Brain Assignment: Day 1 BRAIN ONE
Get a brain and a pink sheet.
On the pink sheet, put the function of each of the 12 brain parts.
On the brain, locate the 12 parts and label your brain.
Make a legend either by colour coding each part or numbering each part so that you know where each of the 12 parts are located.
Put an image or key word beside each brain part or beside the legend.

On the yellow sheet put the function of each of the 6 brain parts.
On this brain, label the 4 lobes of the brain and the motor and sensory cortex.
Make a legend either by colour coding each part or numbering each part so that you know where each of the 6 parts are located.
Put an image or key word beside each brain part or beside the legend.

13. Older Brain Structures
The Brainstem (1) is the oldest part of the brain, beginning where the spinal cord swells and enters the skull. It is responsible for automatic survival functions.

14. Brain Stem: Medulla
The medulla (2) is the base of the brainstem that controls heartbeat and breathing.

15. Brain Stem: Pons
The pons (3) above the medulla are responsible for sleep.

16. Brain Stem: Reticular Formation
Reticular Formation (4) is a nerve network in the brainstem that plays an important role in controlling arousal.
Reticular Formation

17. Thalamus
The Thalamus (5) is the brain’s sensory switchboard, located on top of the brainstem. It directs messages to the sensory areas in the cortex and transmits replies to the cerebellum and medulla.

18. Cerebellum
The “little brain” cerebellum (6) attached to the rear of the brainstem. It helps coordinate voluntary movements and balance.

19. The Limbic System
The Limbic System is a system of neural structures at the border of the brainstem and cerebrum, associated with emotions such as fear, aggression and drives for food and sex. It includes:
pituitary gland, (7)
amygdala (8)
hypothalamus (9)
hippocampus (10)
OBJECTIVE 13| Describe the structures and functions of the limbic system, and explain how one of these structures controls the pituitary gland.

20. The Pituitary Gland (7) is
often referred to as the “master gland” as it regulates many activities of other endocrine glands. It also produces the growth hormone.

21. Amygdala
The Amygdala (8)consists of two almond-shaped neural clusters linked to the emotions of fear and anger.

22. Hypothalamus
The Hypothalamus (9) lies below (hypo) the thalamus. It directs several maintenance activities like eating, drinking, body temperature, and control of emotions. It helps govern the endocrine system via the pituitary gland.

23. Hippocampus
Hippocampus (10) (Latin for seahorse) is associated primarily with memory.

24. The Cerebral Cortex (11)
The intricate fabric of interconnected neural cells that covers the cerebral hemispheres. It is the body’s ultimate control and information processing center.
OBJECTIVE 14| Define cerebral cortex and explain its importance fro the human brain.

25. Corpus Callosum
The corpus callosum (12) is a thick band of fibers that connects the two hemispheres and passes information back and forth to each hemisphere.

26. Brain Activity: Day 2 BRAIN TWO
Go to side 2 of your brain
On this brain, label the 4 lobes of the brain and the motor and sensory cortex. Make a legend either by colouring code each part or numbering each part so that you know where each of the 6 parts are located.
On the green sheet, and on the labelled brain side 2, put the function of each of the 6 brain parts.

27. Brain Parts Side 2 Frontal lobe Parietal lobe Occipital lobe
Temporal lobe
Motor cortex
Sensory cortex

28. Structure of the Cerebral Cortex
Each brain hemisphere is divided into four lobes. These lobes are:
Frontal lobe (1) (forehead)
Parietal lobe (2) (top to rear head)
Occipital lobe (3)(back head)
Temporal lobe (4) (side of head).
OBJECTIVE 15| Identify the four lobes of the cerebral cortex.

29. Parietal Lobe
Occipital Lobe
Frontal Lobe
Temporal Lobe

30. Brain Lobes
The Frontal Lobes are involved in speaking and muscle movements and in making plans and judgments.
The Parietal Lobes receive sensory input for touch and body position.
The Occipital Lobes receive visual information from the opposite visual field.
The Temporal Lobes receive auditory information primarily from the opposite ear.

31. Functions of the Cortex
The Motor Cortex is the area at the rear of the frontal lobes that control voluntary movements. The Sensory Cortex (parietal lobe) receives information from skin surface and sense organs.
OBJECTIVE 16| Summarize some of the findings on the functions of the motor cortex and the sensory cortex, and discuss the importance of the association areas. Map is called Homunculus…latin for little man

32. The Brain’s Plasticity
The brain is sculpted by our genes but also by our experiences.
Plasticity refers to the brain’s ability to modify itself after some type of injury or illness.

Watch the brain that changes itself
Ellen Degeneres rubber hand episode
OBJECTIVE 18| Discuss brain’s plasticity following injury or illness.

33. The Split Brain Experiments
Roger Sperry, in the 1960s, carried out his most famous experiment, the split brain experiment. It was a cure for people who suffered from a special kind of epilepsy. The corpus callosum was severed which stopped the seizures however some odd behaviours resulted. Read more... Watch: Split Brain
