The Emotional Brain

Posted Leave a commentPosted in Biology, Neuroscience, World Brain Day

by Alyssa Khoo Abstract Emotions play one of the most integral roles in human experience and yet are often considered one of the most enigmatic to explain scientifically.[1] Evolutionarily speaking, emotions contribute greatly to the ability to survive. For instance, fear would trigger an almost instantaneous ‘fight or flight’ response to allow an individual to […]

The Evaluation of Extracurricular Activities to Improve the Quality of Life for People with Down Syndrome

Posted Leave a commentPosted in Health, Neuroscience

Abstract People with Down syndrome (DS), an intellectual disability that limits cognitive ability[1], have a lower quality of life (QOL) compared to the typical population. There have been many studies exploring possible methods of increasing DS QOL: three key solutions are friendship, physical activity, and sheltered environments.[1] Since extracurricular activities incorporate all three of these, […]

How Reliable is fMRI as a Neuroimaging Tool to Study Visual Experiences in Dreaming?

Posted Leave a commentPosted in Biology, Neuroscience

Abstract The nature of dream is private. It is impossible to render the dreaming experience public until scientists discovered the association between dreaming and activation of the brain, followed by the invention of neuroimaging tools, such as functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG), to study brain activities during dreaming. Hence, the construction of […]

Earthworms, Salamanders and Humans: A Pathway to New Discoveries

Posted 1 CommentPosted in Biology, Medicine, Neuroscience

Abstract Our world is one of much diversity, with over thirty million species of insects alone. What makes this diversity more incredible is the amount of similarities that many organisms share. These parallels can be harnessed in ways that allow us as humans to take advantage of our similarities with other organisms and use them […]

Acute Tubular Necrosis (ATN) From Intravenous Immune Globulin (IVIG) Treatment for Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) Abstract: Infusions of IVIG are used to treat immune deficiency states, autoimmune disorders, and infections. IVIG Explanation and its relation to the Immune System: The immune system is a network of tissues and organs that work to defend the […]

Does Classical Music Improve Short Term Memory?

Posted 3 CommentsPosted in Biology, Neuroscience, Other, Psychology

A study by Zurafa Sakel.   Abstract The aim of this study is to explore whether classical music can improve short term memory in healthy volunteers. This may help learning of healthy people. It may also have a positive impact on communication and interaction as well as reducing agitation in dementia patients. This standardised prospective […]

Investigating the mouse brain for sex differences

Posted Posted in Neuroscience, Other

Genes located only on the Y chromosome are male specific and are thus not expressed in female cells, which results in gene dependent sex differences. One of the genes located on the Y chromosome and expressed only in male cells is Kdm5d. In our study, the hypothalamus was compared between female and male SF-1 KO, intact WT and gonadectomised WT mice to investigate the genetically and hormonally dependent differences between the expression of the protein encoded by the Kdm5d gene. Standard immunohistochemical staining on floating brain sections was used to visualize the Kdm5d protein and was further analysed under the microscope. Immunoexpression of Kdm5d protein was observed only in WT intact males, but was not detected in any other groups. This observation suggests that the expression of the Kdm5d protein is both genetically and hormonally conditioned. Further experiments with testosterone supplementation should be carried out to confirm our findings. 

Is it more important to understand the mind or the brain?

Posted 2 CommentsPosted in Biology, Neuroscience, Psychology, Science News

  Here, we are faced with the fixed, biological complexity of the brain and the intricate concept, which is open to vast influential change, of one’s mind. The question proposes the task of whether the understanding of the brain or that of the mind holds more significance. However, what this discussion essentially requires is the […]

Remember that time?

Since everyone in Years 11 and above will be, or at least should be, studying for exams around this time of year, it might be fun to think about the actual process of learning/memory itself. Before we start though,  it’s worth mentioning that with a topic like this it is far too easy to start considering […]
