• Watch the following clip
• How is brain surgery different today
different from brain surgery in the 1940’s?
• Why did the patient need to be awake?
Learning Objectives
• Describe the
structure of the
brain.
• Recall how scientists
learn about the
brain.
• Discuss some of the
ethical issues
involved in the study
of the brain.

For the end
of the lesson
On the right
hand page
you are going
to make
notes and
complete
activities
throughout
the lesson
Paired interview
Read through the information on your card.
Make summary notes in your exercise books
(you can talk to your partner about this!)
Don’t forget to write title and the date!!
Paired interview
In pairs interview the pair opposite about the
information on their card.
Your pair will then be interviewed.
Make notes about the other pairs information
You can only do that AFTER the interview is
finished
The Brain
• Simple Animals – have a large mass of
neurons at the head end
• Complex animals – have a brain made of
billions of neurons
– It has many areas, each carry out a
function
– Allows you to learn from experience

the brain
Brain Role Play
Survival
Cerebellum
•
•
•
•
Latin for “Little Brain”
Primitive part of the brain
Survival
Responsible for Fight or Flight and
Reproduction
Brain Role Play
Emotional (1)
Temporal Lobe 1
• Links the nervous system with the
endocrine system
• Release oxytocin from pituitary gland
(Chemical of love)
• Responsible for protection and
nurturing instincts
Brain Role Play
Emotional (2)
Temporal Lobe 2
• Storage of traumatic memories
• Fear conditioning (e.g. phobias)
• If the amygdala is damaged then
organisms can become fearless
– Is this a good thing?

Brain labelling
• Use the information around the room to
label your diagram of the brain.
• Add detailed notes from the slide to your
diagram.
Finding out about the brain?
How do we know about the
structure and function of the
brain?
Finding out...
MRI and fMRI scans
are one way we find
out about the
structure of the
brain.
The patient is awake
The skull is not cut
open
Normal life can
continue after the
scan
Injured Brains
• Awake Brain Surgery
• People who have had
accidents e.g. Phineas
Gage
• Stroke Victims
• Are there any problems
studying brains in this
way?
Finding out...
write down some
ethical issues
associated
with finding
out about the
brain in this
way
Past Question
Stuart is a doctor studying the Cerebral
Cortex of the brain. One of Stuart’s
patients has damage to her cerebral
cortex. Suggest two processes that are
most damaged by this. [2 marks]
Suggest how Stuart could find out exactly
which parts of the brain are damaged [2
marks]
Answers
a) Memory, speech,
b) Look at images on an MRI Scan, apply
an electrical charge to different parts
of the brain.

Jokes show how much you get
it – draw your own cartoon
with a joke about the brain to
make someone else in the
class laugh…
