The aim of this study was to see if Schizophrenia-like symptoms could be induced in non-human animals
It was an animal, laboratory experiment using Amphetamines - to induce symptoms of Schizophrenia. They worsen the symptoms by releasing Dopamine at the central Synapses. Rats were injected with doses of 1-20mg of Amphetamines.
All known Schizophrenic symptoms were reported, including stereotypical activity.
Experiments with a number of different animals show stereotypical Schizophrenic activity can be produced by Amphetamines. This supports the theory that Dopamine contributes to Schizophrenia -(The Dopamine Hypothesis).
+ Symptoms were reversed when rats were given Neuroleptic drugs which work by inhibiting Dopamine activity
+ Synthetic L-Dopa increases Schizophrenic symptoms and can induce symptoms without actually having Schizophrenia
+ PET Scans showed similar findings in live patients (Wong et al - 1986)
- Reductionist explanation
- Ethics and Generalisability (Animal experiment so cannot be generalised to humans; Rats may have been put under some pain)
