About this study

The study will consist of four occasions with one week between the occasions. fMRI will be performed to monitor hypothalamic activity before and after an ingestion of 1 of the following 4 stimuli (300 ml of each): water at room temperature, water at 0 degrees Celsius, glucose solution at room temperature, glucose solution at 0 degrees Celsius. The last two stimuli both contain 75 gram glucose. The order of conditions will be randomly assigned to the subjects. Functional connectivity of the hypothalamic regions will be assessed by analysing the resting state fMRI.

Read the detailed description

Background of the study: Thermo-regulation is an important aspect of human homeostasis. A decrease in brain and/or body temperature will increase energy requirements and eventually food intake, which acts as a defence against hypothermia. The hypothalamus plays a central role in the regulation of temperature as well as in the control of energy intake, feeding behaviour and lipid and glucose metabolism. The effect of both cooling and changes in energy demand, will therefore be reflected in hypothalamic activity.

Functional magnetic resonance imaging (fMRI) is a non-invasive method, which detects transient haemodynamic changes in the brain, using blood oxygen level dependent (BOLD) signal differences in response to external or internal stimuli. Recently, several fMRI studies have shown the feasibility of measuring hypothalamic function in response to glucose ingestion.

In order to investigate the role of hypothalamic neural activity in response to cooling by food temperature and the additional effect of glucose concentration, fMRI will be performed in healthy men after ingestion of one of 4 solutions at different temperatures and with different glucose concentration.

The study will consist of four occasions. There will be an interval of at least one week between the occasions. On all occasions, the subject will be admitted to the Clinical Research Unit of the LUMC. After a acclimatisation period of 30 minutes and anthropometric measurements (weight and height), fMRI to monitor hypothalamic activity will be performed after an ingestion of 1 of the following 4 stimuli (300 ml of each): water at room temperature, water almost frozen (0 C), glucose solution at room temperature, almost frozen glucose solution (0 C). The last two stimuli both contain 75 gram glucose. Conditions will be randomly assigned to the subjects, a batch wise randomisation procedure will be followed. The order of allocation of each subject is recorded on paper and stored in a sealed envelop, which will be opened after inclusion in the study. The hypothalamus will be continuously imaged for 20 min. (8 min baseline, 4 min drinking, 8 min post ingestion) using a conventional T2*-weighted gradient-echo pulse sequence. A resting state fMRI will be carried out before and after the fMRI of the hypothalamic activity. Hedonic changes or reward effects of the administration will be captured by separate analysis of the amygdala and nucleus accumbens in each subject.
