ADVANCED BIOPSYCHOLOGY
Build on your knowledge and understanding with this course. If you have a good grasp of brain anatomy, chemicals and processes, then this course will help to expand your knowledge. Find out how drugs and damage to the nervous system affect brain functioning and behaviour.
DEVELOP A DEEPER UNDERSTANDING OF LIFE
This is a stand-alone course that complements our Biopsychology I module. If you have no previous studies in this area then it is wise to take Biopsychology I first.
Learn about research into complex brain processes such as memory systems, and the effects of brain damage and other factors on those processes.
People working or studying in the areas of counselling, psychology or health will benefit from the deeper understanding of the relationship between our physiological states and our mental processes and how these influence behaviour.

What can Go Wrong with a Brain?
The brain is extremely specialised and complex. Due to this complexity, the slightest damage can have serious consequences. The brain can be damaged in many different ways and it depends on the severity and the area damaged, as to how harmful the damage is. These are some causes of brain damage:
- Brain tumours are a mass of cells that grow independently from the rest of the body. More cases of brain tumours are detected now due to sophisticated techniques. The growth of cancerous cells puts pressure onto the brain, which can cause a blood clot or directly cause brain damage due to the pressure of the tumour.
- Cerebrovascular disorders Include bleeding in the brain or a disruption of supply to the brain. Lack of blood to the brain can cause problems for the cells that are associated with the brain. Humans can survive for around four minutes without oxygen, before the brain damage becomes severe, leaving little realistic chance of survival. A stroke can lead to a blood shortage to the brain, which is caused by a blood clot.
- Closed head injuries are injuries which do not penetrate the skull. Contusions cause bleeding and are generally caused by the brain slamming against the skull. A sufficient blow to the head can supersede the skull’s defences (particularly at the temple) and can therefore allow structural damage to occur.
- Infections of the brain An invasion of the brain by micro-organism is a brain infection, and resulting inflammation is encephalitis. There are two common types of brain infection: bacterial infections and viral infections.
- Neurotoxins The nervous system can be damaged by exposure to any one of a variety of toxic chemicals, mercury and lead can accumulate in the brain and permanently damage it producing a toxic psychosis.
- Genetic factors such as chromosomal anomalies, abnormal recessive genes or faulty dominant genes can lead to a range of disorders such as Down’s syndrome, Huntington’s disease and phenylketonuria. A dysfunctional hereditary gene could be passed on to offspring preventing the brain from fully developing.
Psychology Can affect the Physical Body, and vice-versa
Excessive stress for a long period can at first cause unpleasant feelings, but in due course, it can cause physical damage to the body, fatigue, and in extreme situations, ultimately death. Excessive stress that causes physical damage has been called dystress (by Syle). The Greek prefix “dys” means bad. Dystress literally means “bad stress”. Some stress is both inevitable, and in some respects, desirable. Dystress (or distress), however, is not desirable.
There are damaging effects to the human body caused by constant stress. Changes in the physiological processes that alter resistance to disease (e.g. blood chemistry changes) and pathological changes (e.g. organ system break down and ulcers) are both manifestations of stress. The body’s defence mechanisms may be affected both directly and indirectly (by promoting behaviours that weaken these mechanisms or that lead to exposure to pathogens).
Modern humans with their new technology, do less physical work, stimulate themselves when tired (television, food, alcohol), and eat when they are not hungry, etc. This actually goes against all natural feelings "signals from the brain". Humans are actually depriving themselves, and this is a major psychosocial cause of stress. Another psychosocial cause of stress is "adaption" overload where people are being faced by constant or rapid change whether it be social, cultural, technological, etc.
Other Learning Options
If you are not sure if this is the course for you, why not have a look at our other psychology courses? Perhaps Biopsychology I or an Introduction to Psychology if you are new to the subject..
How this Course Might Benefit You
This course builds on studies undertaken in Biopsychology I and assumes students have some understanding of brain structures and functions. There is greater emphasis on the effects of brain damage and drugs on behaviour and the higher cognitive functions of memory and language are explored in detail. Graduates of both biopsychology courses will feel confident that they have a thorough grounding in the functions of different brain centres.
This course may be studied by itself or as part of a certificate or higher level course. The course will be most interest to those working in or planning to work in:
Psychology
Psychotherapy
Teaching
Research
Biological sciences
Health sciences
