Our brain is a web of neural cells, continuously transmitting and processing information. This process is enabled by mediators: they convey our desires and fears to our body and affect our energy level and mood. They are the main focus of the course
About the Course
The eight lessons provide an understanding of how the nervous system works and how our brain functions in terms of chemistry. We will also explore the impact of antidepressants on the brain, the causes of alcohol and nicotine addiction, and the reasons why some people are all sunshine and smiles while others are perpetually unhappy
Video Lectures
Each session consists of 5–6 video lessons lasting 10–20 minutes each
Lifetime Access
You can take the course at your own pace. The videos will remain in your account forever

For Any Level
This course is suitable for those who start exploring the subject from scratch, as well as for those who want to arrange their current knowledge
You Will Learn:
How antidepressants, tranquilizers, and neuroleptics work
How mediators help us focus on our job and maintain concentration
Why smokers hate starting their working day without a smoke
What makes some of us go looking for trouble
How stress helps us memorize things
Why we enjoy food and sex so much
Course Curriculum
lesson 1
+
Axons, dendrites, synapses
How Neural Cells Work
Our neural system includes around 100 billion neurons. Quite useless on their own, together they form chains and networks, helping us coordinate our movements, laugh at jokes, enjoy a good meal, and much more
The lesson explains the formation of neural connections and the structure of neural cells. You will learn what molecules play an active part in our brain and how to tell between axons, dendrites, and synapses. We will also describe the tissues constituting the brain and the spinal cord
lesson 2
+
Synapses, Botox, the role of calcium and magnesium
How Mediators Work
You feel like having porridge for breakfast. A simple thought – but for it to appear, dozens of synapses have sequentially fired up in your brain. Synapses are the crucial nodes of the nervous system, transferring signals from neuron to neuron, like telephone cords, and determining how quickly we think
The lesson focuses on synapses and how they work. You will learn about mediators, their production, and their impact on neurons. You will find out which substances activate our receptors and which block them and understand how this principle feeds into the efficiency of medical drugs and narcotics. We will explain how calcium and magnesium affect the speed of information processing and why this process matters
lesson 3
+
Acetylcholine, nicotine, atropine, and nerve agents
The Brain, Movement, and Visceral Regulation
The first mediator discovered by scientists was acetylcholine. It has a simple structure but affects hundreds of processes. Any muscle contraction is a discharge of acetylcholine (and we have over 600 muscles in our body!). It is also responsible for our anxiety and calmness
In the lesson, you will learn how acetylcholine helps us coordinate our movements and handle stress. We will explain why smokers find it hard to get down to work without a cig and why we sweat when we are nervous
lesson 4
+
Noradrenaline and adrenaline
The Brain and Stress
Noradrenaline is involved in visceral regulation along with acetylcholine, boosting or reducing the activity of internal organs. This mechanism helps us handle stress and emotional or physical strain, which includes all energy-consuming activities: running, feeling anxious about an event, or handling issues
In the lesson, you will learn how scientists and doctors use noradrenaline to manage asthma and running nose symptoms and regulate vascular function. You will find out when stress is beneficial and boosts our memory skills and when it is detrimental. We will also explain why some people cannot imagine their life without extreme sports, gambling, and other adventures
lesson 5
+
Glutamate and gamma-aminobutyric acid (GABA)
The Brain and Energy
Glutamate is the main excitatory neurotransmitter, while gamma-aminobutyric acid (GABA) is the chief inhibitor. Together, they make sure we can multitask or stay focused on the job at hand and determine how quickly we react and how alert or sluggish we feel
The lesson explains how these mediators work and provides insight into the actions of tranquilizers. You will find out what helps you maintain concentration and keep a lid on your emotions. You will learn how glutamate in your brain affects sensory organs and memory and what it has to do with its counterpart used in foods. We will show how these mediators are used to curb epileptic seizures and normalize the heart rate
lesson 6
+
Dopamine, neuroleptics, and psychomotor stimulants
The Brain and Emotions
It may seem that dopamine is the “all-around good guy” among mediators. It is responsible for physical and cognitive activities and positive emotions. People with a high level of dopamine enjoy doing sports, are great at mastering programming languages, can think outside the box at work, and make good jokes
However, excessive activity of the dopamine system may lead to schizophrenia. The lesson explains how dopamine works, why its deficiency is a cause of depression, and how to regulate the dopamine system function with neuroleptic drugs
lesson 7
+
Endorphins and opioids, oxytocin, substance P, peptide toxins
The Brain and Narcotic Drugs
The endorphin system and associated drugs alleviate pain. However, such drugs cause habituation and dependence, which is hard to fight
In the lesson, you will learn why drugs that affect the endorphin system are the most dangerous. We will explain how the brain responds to opium, morphine, and heroin and why these substances cause euphoria
lesson 8
+
Histamine, glycine, anandamide and cannabinoids, adenosine and caffeine, alcohol
The Brain and Other Addictions. Allergies
We will conclude our foray into brain chemistry with an overview of mediators varying in functions. We will start with histamine, which is responsible for inflammation if we hurt ourselves or catch a virus and also causes the symptoms of allergy. Next, we will examine glycine and adenosine, which protect our muscles and brain from overwork
In the lesson, we will address the working mechanisms of these mediators and see how coffee and alcohol impact their production. You will learn why caffeine gives you a boost of energy and a small dose of alcohol lifts your spirits, while a bigger amount makes you sleepy

Engaging, accessible, and fun. Examples from daily life and the animal world are the best! The lecturer was also great. Many thanks!
Maggie
This course was much anticipated. The information is accessible and well-structured. You feel like listening more and more
Eleonora
In-depth delivery coupled with vivid images and parallels
Lilly
A great course for those interested in the brain and its structure and those who want to understand why we act one way or the other in a given situation
Elena
There are plenty of courses out there.
However, few are worth your while.
Thank you so much for your project!
Jessica
A fantastic course! A great deal of very useful information! Indeed, the course includes a lot of special terms, so it takes some cramming and revision, but its scope and the opportunity to look beyond the school curriculum are very inspiring
