Objective: Essence of chicken extract (ECE) has been known as health promoting food in South Asian countries, e.g., Singapore for its effect on stress relief and improvement in cognitive ability. This study investigated to see if ECE ingestion improves cognitive ability.
Method: Subjects included 27 male and female under graduate students who voluntarily participated in the study. They were randomly assigned into two groups, control and experimental. The experimental group ingested a bottle of ECE (21.6 Kcal, 5.4 gram protein, 63 mg sodium, and 68 ml per bottle) each morning for two consecutive weeks while the control group took a placebo (caseinate based placebo with caramel & flavor, 68 ml per bottle). Two groups were then to complete the Tower of London (TOL) task (Shallice, 1982) during the fMRI administration. After a five-week long recess, the two groups switched the experiment and were followed by a second fMRI. Essence of chicken extract and placebo were supplied by Cerebos Pacific Ltd. Singapore. Imaging was performed on a Siemens SONATA 1.5T Scanner. Single-shot EPI fMRI scans (TR/TE 3000/35ms, Flip Angle 90, FOV 24*24cm, Matrix Size 64*64) were acquired. Imaging data were motion-corrected, co-registered, normalized and statistically analyzed as a group using SPM2 (Welcome Department of Imaging Neuroscience, London, UK).
Result: The areas with more activation in the ECE condition than the placebo were observed. They were the right superior medial frontal gyrus, the bilateral superior frontal gyrus, the right postcentral gyrus, the right anterior cingulate gyrus, the left inferior frontal gyrus, the left middle temporal gyrus and the left precuneus (paired t-test analysis). The results obtained in this study are consistent with the one in the previous studies that both left and right DLPFC are involved in the TOL task.
Conclusion: This result showed a great potential that ECE ingestion must have facilitated the activation of the brain areas associated with TOL task processing. Therefore, this study outcome serves a neural basis that supports ECE helps with cognitive processing in the humans.
