The Olfactory Bulb: Function and Characteristics

Smells have the power to evoke fond memories. Not only can your sense of smell transport you to the past, but it also helps you make important decisions every day. Today, we’re going to talk about an essential part of your…

The Four Types of Attention

Understanding that there are multiple types of attention is important. Most people believe attention is the ability to focus. Anytime someone is distracted or simply not listening to you, you say they’re “not paying attention”. But here’s our question: is…

Isolated Brain – Living without a Body

Recent studies made us question whether an isolated brain can have a life of its own after the body dies. Can it be alive on its own? Let’s find out. Our brain is the “operating center” of our body, it…

Victor Leborgne – A Case in Neuroscience

The brain of Victor Leborgne is probably the most studied in the history of neuroscience. It’s still preserved in the Musee Dupuytren in Paris and scientists have examined it thousands of times. However, until a few years ago, there was…

The Neocortex: Its Structure and Functions

Everything that we are, feel, and, more importantly, what we can become, is stored in our brain. Much of our evolutionary success is thanks to the neocortex, also called the isocortex. It’s a newly-discovered and extensive region that makes sophisticated processes…

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

Nitric oxide is a neurotransmitter with amazing functions. For example, it aids our memory, conditions the quality of our sleep, and can even boost our sexual relationships. In this article, we’ll explore in detail how it works. Millions of substances…

Working with Your Hands Is Good for Your Brain

Working with your hands is a way of improving your mental health. Modeling clay, knitting, shaping, sculpting, sewing, gardening, and painting, among other activities, are wonderful ways to stimulate your brain. They’re also a great way to relieve stress, improve…

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…
