Neural Mechanisms - Studies

Sakuri (1998) 

Eating behaviour is controlled by neural circuits that run through the brain. The lateral hypothalamus may not be the brain's 'eating centre'. This research involved using rats. 

Gold (1973) 

- Lesions to the VMH alone did not result in hyperphagia in rats and only had effect when PVN was also damaged.
- Subsequent research failed to replicate Gold's findings.

Marie et al (2005) 

Genetically modified rats (without NPY) had no change in eating behaviour. 

Rolls and Rolls (1973) 

Surgically removing the amygdala in rats would cause them to consume familiar and unfamiliar foods. 

Zald and Pardo (1997) 

The amygdala participates in the emotional processing of olfactory stimuli.
