On researching about recent scientific innovation, and skimming through several news
articles, and science blogs, chronic stress related research, emerged as area of interest. While
reading the news article released by “The Newyork Times” in 2009 on “Brain Is a Co-
Conspirator in a Vicious Stress Loop”, an interesting fact was indentified. It relates to the
reversibility of the stress induced changes in the brain and the behaviours. The article presented
information from recent researches in the area of behavioural perturbations in mice associated
with the changes in the underlying neural circuitry (Angier, 2018). To further explore this are the
paper discusses the results and findings of the article, titled, “Feeding the developing brain:
Juvenile rats fed diet rich in prebiotics and bioactive milk fractions exhibit reduced anxiety-
related behaviour and modified gene expression in emotion circuits” by Mika et al. (2018).
It was found in the news article by Angier (2018) that chronic stress has adverse
outcomes such as rise in blood pressure, risk of diabetes and suppressed immune system.
Chronic stress is self debilitating to life due to emergence of long term illnesses like Alzheimer’s
disease, and short term conditions like depression. The article cited evidence from primary
research conducted in the chronically stressed rats. The rats demonstrated low
elastic rat cunning and behavioral perturbations like pressing a bar for food
pellets compulsively without intention of eating. Further examinations of the
rats showed that the regions of brain responsible for goal-directed behaviors
and decision-making were shrivelled. Such behaviours lead to habit formations not only in
animals but also in the human beings (Schwabe & Wolf 2013). Drawing on valuable insights
from the news article, the interest to further learn about potential solution to combat stress related
affects on brain. The issue calls for remedies to curb this problem in early stages to avoid
chronicity. Several researches have been conducted in juvenile rats and mice models to reverse

the effect of the stress on brain centres. One such research that appeared very innovative was the
one by Mika et al. (2018). In this fast pacing world, stress is inevitable and to reduce the
debilitating illness solution is indeed crucial.
Mika et al. (2018) argued that brain development requires early life nutrition. It was
considered critical Dietary prebiotics and bioactive milk factions provide nourishment to the
brain by alerting activity in the regions responsible for the cognition and emotional regulation.
Based on the previous researches the author developed the research question. It was to identify
the impact of the diet rich in lactoferrin, prebiotics, and milk fat on brain circuits. The researcher
studied the impact of the multi-ingredient diet (containing, lactoferrin, GOS, PDX,MFGM) on
the beneficial gut bacteria as well gene expression for the plasticity (NMDA receptor subunits,
BDNF, serotonin receptors) and activity (earl gene cfos) markers.
It can be concluded from the findings f the research that the adaptive emotion regulation
in juvenile mice was obtained by feeding the mice with prebiotic containing diet as well as
lactoferrin. These mice fed in the early years showed increase in Lactobacillus spp., gene
expression. It was increased for molecules involved in neural plasticity as well as activity in the
prefrontal cortex. On the other hand, the reduced activity related gene expression was found for
amygdale region. Overall it can be concluded from the findings that such early life diet have high
potential to alter the genes responsible for emotional regulation in the neural circuits. It had been
found effective for reducing the anxiety related behaviour in juvenile mouse when compared
with the controlled rats not fed with prebiotics.
This research has important implications for chronic stress reductions responsible for
negative health outcome such as disturbance of the sleep cycle. It has been supported by the
the effect of the stress on brain centres. One such research that appeared very innovative was the
