  • General introduction to the importance of understanding the biological bases to behaviour.Give examples of how biology can change behaviour – such as someone who is visually impaired will have different experiences to someone with sight
    This is one half of the nature nurture debate
    Make sure that the group do not think that they have to understand every detail of how the Central and peripheral nervous system operates – they just need to get a grasp of the basics.
  • These slides are to show how the brain is structured and to raise general issues relating to the research into how each area functions and contributes to the whole. Emphasise the point that if any part of the brain does not function, then this has implications for how the rest of the brain functions. This shows the interconnectedness of the different areas of the brain and the two relationship between brain and body.
  • This slide is just to flag up what we are going to deal with how the brain communicates within itself through the action of neurons, axons and neurotransmitters – the chemical messengers in the brain
  • Load the hyperlink – the structure of the neuron is the first slide of 24. The synapse slide is in the next 2. Click through the slides quickly and spend more time on the relevant ones. This hyperlink also explains how drugs interact with the neurotransmitters in some cases and how some drugs work by occupying receptor sites within the synapse.
  • The role of the endocrine system as the chemical messenger system within the body. Hormones as the chemical messengers and the endocrine system as the ‘Post office’.
  • Discuss:
    The way the spinal chord carries information to and from the body (Afferent and efferent pathways)
    The way that pain is perceived and transmitted
    What a reflex action is. (This can be demonstrated using a line of students as the pain pathway)
  • The Pituitary gland is the main link between the brain and the endocrine system. Don’t go into great detail – it has a very complex structure and action – it will suffice to look at the pituitary as the connection. The Pituitary gland is the main link between the brain and the endocrine system. Don’t go into great detail – it has a very complex structure and action – it will suffice to look at the pituitary as the connection.
  • The role of the endocrine system as the chemical messenger system within the body. Hormones as the chemical messengers and the endocrine system as the ‘Post office’.
  • How hormones are the chemical messengers in the body
    Stress and hormones
    Link to nature v nurture
  • Discuss how both haemorrhage and stroke can alter the behaviour in terms of:-
    Aphasia
    Memory loss
    Personality change
    Mood swings
    Paralysis.
    Show slide from CNS pathology of a brain clot and brain damage due to haemorrhage
    2. Different brain tumours – changes in behaviour
    3.Accidental damage – Phineas Gage (go back to hyperlink of the neuron , last slide (24)

It also links in with the endocrine system in the
