Enkephalin: A Pain-Relieving Neurotransmitter

People have been studying the role of enkephalin in pain transmission for over three decades. Enkephalin is a hormone that acts as a neurotransmitter that allows neurons to communicate. It’s a hormone your brain produces in certain areas such as the pituitary…

The Hindbrain: Structure and Functions

Throughout history, scientists have categorized the brain into several parts to try and better understand its functionality and development. One of those parts is the hindbrain, or rhombencephalon, a region that comes from the caudal primary embryonic vesicle. The hindbrain…

Brain Plasticity: Characteristics and Types

The term “brain plasticity”, also known as neuroplasticity, is related to our nervous system’s ability to modify itself both functionally and structurally. This happens naturally as time goes on, but also in response to injuries. In a literal sense, plasticity is a…

Nitric Oxide: The Amazing Gaseous Neurotransmitter

The Neurobiology of Alcoholism

Just as there are neuroanatomic and neurofunctional frameworks to explain human behavior, we also have the neurobiology of alcoholism. In this article, we’ll explain what happens in the brain of a person with alcohol addiction. Alcohol is the most widely-used…

The Blue Brain Project: A Reconstruction of the Brain

Just like astrophysicists look outside of our planet to discover how space works, neuroscientists look inside the human body to unravel the brain. Such an ambitious goal, a common aspiration among scientists for decades, is now an actual research project.…

Key Exercises for Cognitive Stimulation

The things we’ve learned in recent years about our brain is very valuable. For starters, we know that it’s elastic and that we can change its structure. We also know that it has cognitive reserves that play a very important…

Intracranial Aneurysm

An intracranial aneurysm is a dilation of a brain artery wall. The most challenging aspect of these vascular conditions is that they tend to present no symptoms. So little by little, and without the affected person noticing it, this area…
