Agonists and Behaviour: PramipexoleDopamine agonists in the treatment of depression
An agonist is a chemical messenger that binds to the receptor sites of neurons and activates them to create a response. In this post, we’ll look at how the drug pramipexole is an agonist of the receptor sites for dopamine. Since dopamine has been linked to depression, we can also understand why this might be another option for treatment. Depression …

Ketamine and PTSDHow an antagonist of glutamate may help treat PTSD
Agonists and antagonists are chemical messengers that affect the process of neurotransmission. They bind to specific receptor sites of neurotransmitters and this can affect brain function and behaviour. Ketamine is one antagonists of the receptor sites of the neurotransmitter, glutamate. In this post we’ll learn more about antagonists, how they work, how ketamine may help PTSD and a key study …

Ketamine is the newest drug in the treatment of major depressive disorder (MDD). But how does it work? In this post, we’ll look at how ketamine is an antagonist of the neurotransmitter glutamate and why this can help fight depression. For years serotonin has been the main focus of causes and cures for depression. As low levels of serotonin and …
Synaptic Pruning and Neural Networks
Synaptic pruning (aka neural pruning)¹ helps the formation of neural networks. In this post we’ll look to understand the terms “synaptic pruning” and “neural networks.” We’ll also look at how synaptic pruning can help the formation of neural networks. What is a “neural network?” A “neural network” is a series of connected neurons. Information travels along these networks that enable …

In the old curriculum, IB Psych Internal Assessments were replications of an existing study. Surprisingly, in the new curriculum a student could technically score perfect marks without replicating an original study or even …
