Nature Conservation – Methods & Motives

Concepts of nature protection Gaia’s hypothesis: Proposes that all organisms on Earth are integrated to create one system, where self-regulating is used to maintain the conditions for life. The organisms that are a part of this system carry out functions to provide an optimal living environment.  Medea’s hypothesis: Believes that the idea of a superorganism

Localization

Localization of function is the idea that specific behaviors have their own location within the brain. This essay will evaluate the case studies of Louis Leborgne and Eugene Pauly while also looking at the studies conducted by Maguire, Lashley, and the split-brain theory.  The first study relating to localization is the case study of Louis

Crash Course Human Biology

Based off the IGCSE curriculum, revision notes by Anna DeVault and Sion Park Interested in human biology? Or biology in general? Are you a stressed IGCSE student? Well you are in the right place, below you will find a window into the IGCSE Human Biology curriculum. Topic 1: Cells and Tissues Functions of basic cell

Evaluation of Case Studies

Biological Approach Using case studies of brain damage is one of the most common ways to study the brain. Frequently, case studies of brain-damaged patients are carried out longitudinally, to be able to observe both the short-term and long-term effects of damage. Most often case studies holistic in their approach, looking at a range of

Viruses!

Viruses are parasites that can only be reproduced in living cells. Viruses are not made of cells so therefore it doesn’t have a nucleus or a cytoplasm. Their genetic material can either be DNA or RNA. They do not eat, grow, respire, excrete, or move, but they do reproduce. Viruses reproduce by entering a cell

Neuroscience Basics

Our brains are a truly peculiar thing. It is unimaginable how our consciousness, subconscious thoughts, reflexes, and much more work together, 24 hours a day. What is even more amazing is how these complex and undiscovered processes can be boiled down to simple chemical and physical processes in our brain. Our brain is composed of

Jump into Genetics!

This is an introduction to our series on genetics: These should be things you already know. What is DNA? Deoxyribsoenucliciacid (DNA) controls the production of proteins within a cell. (DNA can also be found in the mitochondria and cytoplasm.) A gene is a segment of DNA that codes for a specific protein. This can lead

Epigenetic in depression part 2: Weissman et al study

From the series: Epigenetics in depression by Anna DeVault Evaluation of Weissman et al: Aim: To establish the genetic connection of Major Depressive Disorder (MDD) Sampling pool: Grandparents, their children, and 161 of their grandchildren. The grandparents were found through an outpatient clinic specializing in mood disorders. The sampling pool included high and low risk

Reacting to Stress: What Every IB Student Should Know

From the series: Well-being for IB students by Szymon Lic In this article, I am going to focus on the ways we can control our emotions by taking advantage of how our mind is connected to the brain. It appears possible to control how we react to different stressful situations. Additionally, stress and reward systems

Localization of function: HM Case Study

Localization of function is the theory that specific parts of the brain are responsible forspecific behaviors or cognitive processes. Some parts of our brain do play certain functions in behavior, but it is rare for a part of the brain to work separately. An example would be in memory research, where psychologists are arguing that
