Synaptic Pruning and Neural Networks


Synaptic pruning (aka neural pruning) 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. This is new material for IB Psychology “additional terms.”

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.


Ketamine and PTSD: How 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 that demonstrates this.
