THE NOBEL PRIZE 2021: Two Americans Win Medicine Nobel for Discoveries in Sensing Temperature and Touch

Abstract The Nobel Prize in Physiology or medicine is awarded by the Nobel assembly [1] for extra-ordinary inventions in physiology and medicine. The Nobel Prize is basically awarded to “those who, during the preceding year, have conferred the greatest benefit to humankind”, according to Alfred Nobel’s will in1895. The Nobel Prize is basically awarded for

How can exercise have an antidepressant effect on the brain through BDNF?

Abstract Regular physical activity has long been known to have positive effects on mood and mental health. In this study, the antidepressant effect of exercise in the brain of patients with Major Depressive Disorder (MDD), which includes symptoms such as decreased mood and motivation caused by changes in the chemical molecules of the brain, was

Comparison of optogenetics with bipolar electrode stimulation as a method to measure conduction velocity through axons

Signal transfer has an important role in the human body: without communication between cells, many processes such as action or perception could not take place. Rapid communication between cells largely goes via the nervous system. Through a mechanism in which a difference in voltage is created by diffusion and conduction of ions, nerve cells can

Neurorehabilitation of paralysis patients using Brain Computer Interfaces

Abstract Brain-Computer Interfaces (BCI) acquire and translate brain signals from a patient to carry out some action on an external device. BCIs may collect these data signals through invasive, semi-invasive, or non-invasive techniques. Such techniques include electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and Electrocorticography (ECoG). This review will aim to understand the development of

Orange You Glad You Aren’t A Bird?

Abstract The wide-ranging adaptations of birds has astounded scientists for many years and the crested auklet (Aethia cristatella) is no exception. Aside from its physical ornamentation and vocalisations, the auklet’s citric plumage-odour is one of its most well-known characteristics. The tangerine-like secretion is used in courtship displays as well as acting as an ectoparasite repellant,

The Effectiveness of Vestibular Substitution via IMU Based Tactile Feedback

Abstract The concept of sensory substitution involves supplying sensory stimuli through a sensory modality usually used for gathering different sensory data. An example of this would be echolocation in blind humans. It is usually our eyes which help us decide how far away objects are, by processing the sensory stimuli we receive visually. However, in

Why are cases of food allergies in developed countries on the rise?

Abstract Allergic diseases have increased by over 50% in the last two decades. To raise awareness, education to children about their management and prevention is urgently needed. This is of rising importance as the number of people dying from food allergies, anaphylaxis and allergic asthma continues to rise at a shocking rate. In case this

Antibiotic-Resistant Biofilm: Challenge In The Development of Antibiotic Therapy

Abstract Pathogens are acquiring resistance faster than the introduction of new antibiotics. A growing number of infections such as pneumonia, tuberculosis, gonorrhoea, salmonellosis, etc are becoming harder to treat due to antibiotic resistance. Therefore, it is the need of the time to conduct research in order to reduce antibiotic resistance by microorganisms. The article will
