University Learning in Schools Biology My brain during the day Lesson 1: Brain Areas
Brain areas Learning Outcomes Identify personal preference of the 2 sides of the brain Explain what is meant by brain specificity and identify different areas of the brain Describe how damage to a certain area of the brain affects the body and behaviour
Starter Complete the questionnaire and find out which side of your brain is more dominant.
Which side? • Give yourself one point for each time you answered “A” for questions: 1, 2, 3, 7, 8, 9, 13, 14,15,19, 20, 21 • Give yourself one point for each time you answered “B” for questions: 4, 5, 6, 10, 11, 12, 16, 17, 18 • Add your points. Totals imply: • 0-4 points: strong left brain • 5-8 points: moderate left brain • 9-13 points: middle brain • 14-16 points: moderate right brain • 17-21 points: strong right brain
What does it mean? • Use the information sheet and check your score with the description. • In your handout write down what your dominant side is, and give examples to support this. You can use the sentence starters to help you: • The most dominant side of my brain is the… • This side is responsible for… • This means that people with a dominant…side are usually... • This does/does not apply to me because…
The Brain Phineas Gage
Brain specificity • Different parts of the brain are responsible for different tasks. • You are going to go on a fact hunt. Label your brain diagram using the information in the room. • All have to label the correct areas in the brain • Most should describe the function of the different parts of the brain • Some could describe what happens when a certain brain area is damaged
Quiz: How well do you know your brain? • Use your notes to write the answer on your mini whiteboard. • Do not hold up your MWB until I tell you. • Are you ready? • Let’s go!
Homework Pick an activity/sport/hobby and • describe what parts of the brain are involved in this activity (C/B grade) • explain how the parts of the brain work together (A) • suggest the effect of damage to one of the brain areas involved on how well you can carry out the activity (A*)
Brain structure Cerebrum Largest part of the brain Senses: vision, hearing, touch, smell etc. Complex movement Thoughts Imagination
Cerebellum • Found at the at the back of your head under the cerebrum • Means “little brain” • Responsible for movement, balance, posture • Often takes over learned activities (e.g. riding a bike!)
Corpus Callosum • Connects right and left hemispheres of cerebrum • Important for the information exchange • Important for coordinate movements, memory, language, comprehension
Frontal Lobe • Found under your forehead • Centre of reasoning • Planning • Some parts of speech • Movement (motor cortex) • Emotions • Problem solving
Effect • Personality • Emotions • Decision making • Solutions to the tasks • Motor learning
Parietal Lobe • Found on the top of your head • Receives sensory input from the skin (touch, pressure, temperature, pain)
Damage • Loss of imagination • Loss of sense of direction • Problems in understanding symbols (reading, writing) • Loss of perception on one side of the body
Occipital • Found at the back of your head • Receives input from the eyes • Often referred to as the visual cortex
Damage • Loss of vision • Hallucinations • Not able to detect movement (can’t drive) • Colour blindness
Temporal Lobe • Found on the sides of your head above your ears. • Functions include: • speech perception • hearing • some types of memory
Hippocampus • Memory • Navigation in the environment
Damage • Memory loss • Inability to recognize faces • Loss of speech • Inability to read and write
Hypothalamus and pituitary gland • Hormones: growth, hunger, thirst, emotional dependence, fear, sexual dimorphism etc.
Damaged/diseased • Gigantism • Central diabetes • Abnormalities of gender features
Pineal gland • Modulation of sleep patterns • Circadian rhythms • What would happen if we damaged it?
Brain stem • Medulla oblongata • Involuntary actions • Digestion • Heartbeat • Breathing What would happen if we damaged it?
