Part 1-5: Your Brain on Porn | Animated Series

Your Brain on Porn

This video is an animated series that discusses the effects of internet porn on the brain and how it can lead to addiction. The video also explains how our brains are not well-suited to many aspects of modern life, including internet porn.

Internet Porn is More Stimulating Than Images

• Internet porn is far more stimulating than just images due to endless novelty and the ability to click from one image to another.

• It can escalate quickly to more kinky or shocking material.

Addictive Personality Not Required for Getting Hooked on Internet Porn

• Many guys who get hooked on internet porn had never had any other addiction before.

• They return to their "normal selves" after a porn session.

Understanding How Heavy Porn Use Affects the Brain is Helpful

• Being hooked on porn is due to the same brain changes that go with all addictions.

• These brain changes keep you coming back even if you want to quit.

Internet Porn as a Super Stimulus

• Internet porn is what we call a super stimulus because it's way beyond anything we've ever encountered during our evolution.

• Our brains have barely evolved in the last 100,000 years, so we're not well-suited for many aspects of modern life, including watching internet porn for hours a day.

Brain Rules: Surviving and Making Babies

• Brain rule #1 says You Must Survive. Which means get calories!

• Evolution's top priority is making more gene packets, more copies of you.

• A heavy porn user would view more hot babes or hot guys in one session than our ancestors would need several lifetimes to.

Conclusion

• This video is an animated series that discusses the effects of internet porn on the brain and how it can lead to addiction.

• Internet porn is a super stimulus that our brains are not well-suited for, leading to addiction.

The Coolidge Effect

This section explains the Coolidge effect, a genetic program that is present in all mammals and governs sexual desire. It also discusses how internet porn takes advantage of this program to become addictive.

The Coolidge Effect

• When a male rat is placed in a cage with a receptive female, he will copulate with her until he tires of her. Replacing the original female with a fresh one will revive his interest and he will continue to copulate.

• In an experiment with rams, it was found that when presented with the same female repeatedly, the male took longer and longer to ejaculate. However, when presented with different females, he ejaculated quickly.

• Heavy porn users often need more novelty to get excited due to the Coolidge effect.

• The primitive parts of our brain are programmed for mate selection and sexual urges. Even if we are happily married or partnered up, these primitive parts can still be activated by porn.

The Limbic System

This section explains what the limbic system is and its role in governing emotions such as fear, joy, anger as well as desires and drives including hunger, mate selection and sexual urges.

The Limbic System

• The limbic system is an ancient part of our brain that we share with all mammals.

• It governs emotions such as fear, joy, anger as well as desires and drives including hunger, mate selection and sexual urges.

Introduction to the Limbic System

This section introduces the limbic system and its role in shaping our mood and decision-making.

The Limbic System

• The limbic system is responsible for our survival instincts, such as avoiding pain and seeking pleasure.

• It is present in all mammals and has similar brain chemicals and structures across species.

• Chemical imbalances in the limbic system can affect our decision-making abilities.

The Reward Circuitry

• The reward circuitry is a small area of the brain that controls desire, pleasure, and decision-making.

• Dopamine is the main chemical responsible for activating the reward circuitry.

• The more exciting an experience, the stronger the reward circuitry is activated.

Dopamine Release

• Dopamine release follows a rollercoaster pattern when we engage in behaviors that further our survival or genes.

• A surge of dopamine leads to increased motivation to seek out pleasure.

• Hedge fund billionaires continue working because they want more dopamine in the form of winning at stock market games.

The Role of Dopamine in the Brain

This section discusses the role of dopamine in driving behavior and addiction.

Dopamine and Novelty

• Dopamine drives individuals towards orgasm, but the feeling of orgasm arises from other neurochemicals called opiates.

• Dopamine loves novelty, which is why it surges when experiencing something new or novel.

• A spike in dopamine can override feelings of fullness or satiety, leading to overeating or watching porn.

The Coolidge Effect

• The Coolidge effect is driven by dopamine.

• As dopamine levels drop with repeated copulation with a female rat, introducing a new female rat leads to another surge in dopamine that surges libido.

• This explains why individuals click on new videos while watching porn: to get another big squirt of dopamine with something novel.

Dopamine as the Molecule of Addiction

• Changes in brain caused by changes in dopamine level lead to addiction.

• All addictive chemicals and activities raise dopamine levels, making them potentially addictive.

• Addictions are chasing after dopamine; wanting more but liking it less.

Power of Reward Circuitry

• Rats will press a lever thousands of times an hour until they drop if it stimulates their reward circuitry with enough electricity.

• Rats will cross an electric grid that causes painful shocks to press the lever but won't undergo shock for food.

• Blocking rats' dopamine leads to no motivation even for eating or sex.

Importance of Dopamine

• Dopamine does lots of important jobs, including giving a positive outlook, good attitude, motivation and happiness.

• Many psychological problems involve dopamine imbalances, including addictions.

Signs of Porn Addiction

This section discusses the signs of porn addiction.

Signs of Porn Addiction

• Withdrawal symptoms such as anxiety, irritability, fatigue, depression and physical symptoms like cold and flu symptoms, headaches, inability to sleep.

• Difficulty controlling use leading to longer usage than desired.

• Understanding negative consequences on mood and health such as anxiety disorder and sexual dysfunction.

• Neglecting or postponing activities in favor of porn use.

• Desire to cut down with unsuccessful attempts to do so.

• Spending significant time or emotional energy obtaining, using, concealing, planning or recovering from use.

Behavioral Addictions

This section discusses behavioral addictions.

Brain Changes that Lead to Addiction

• Behavioral addictions cause brain changes that lead to addiction similar to dopamine-raising substances like alcohol, cocaine or meth.

Internet Porn Addiction

• Research on gambling and food has shown brain changes that mimic drug addiction but there hasn't been much study on internet porn due to it being a recent phenomenon.

Natural Reinforcers

• Natural reinforcers are non-drug activities that cause dopamine release such as food, sex, gambling and video games.

Potential for Addiction

• Only 15% or less of drug users become addicted while natural reinforcers have a higher percentage of people who can become addicted over a longer period.

Highly Stimulating Versions

• Highly stimulating versions of food and sex can hook us even when we're not genetically susceptible to substance addictions.

When Natural Reinforcers Become Addictive

• Natural reinforcers become addictive when they are a highly stimulating version of what our ancestors found really irresistible, available in limitless supply, comes in lots of varieties and we binge on it without realizing it's triggering brain changes.

Natural Reinforcers and Addiction

This section discusses natural reinforcers and addiction.

Brain's Natural Satiation Mechanisms

• Modern food and internet porn fall into all four categories of becoming addictive as they override our brain's natural satiation mechanisms leading to overconsumption.
