BNS3021 - Neurochemistry and Behaviour

Leader(s): Dr Glenda Bishop

Offered

Clayton First semester 2009 (Day)

Synopsis

This unit examines how the chemistry of the nervous system influences behaviour. It addresses the nature of neuronal communication and how neurotransmitters interact with receptors to send signals to other brain cells. Emphasis will be placed on the regulation of homeostasis and behaviour by neurochemicals and hormones. The role of glial cells in controlling key metabolic pathways in the brain will also be reviewed. Lastly, this unit will examine how synaptic plasticity and biochemical changes underpin memory formation.

Objectives

On successful completion of this unit, students will be able to:

1. Explain the methods used by the nervous system to exchange information by releasing neurotransmitters and the interaction of these neurochemicals with specific receptors;
2. Describe how the nervous system regulates the homeostasis of the body and behaviour via neural connections and the release of neurochemicals and hormones from the brain and other organs;
3. Recognise the role that glial cells have in controlling the biochemical balance of the nervous system and how they protect neurones from stressors and pathogens;
4. Identify and describe how synaptic function and plasticity are altered through physiological and environmental influences, and how synaptic plasticity and biochemical changes promote memory formation;
5. Demonstrate careful observation and documentation in experimental work;
6. Evaluate the importance of scientific findings and interpret and discuss these findings in written and oral presentations
