Habits: the Good, the Bad, and the Sticky
Ever wondered why some habits seem to stick like glue, whether good or bad?
Why do certain habits become deeply ingrained in your daily life, while others fade away?
Do you want to kick-start lasting change and break free from unwanted habits?
Well, you are in the right place. Here the neuroscience behind habit formation will give you the answers!
Neuroscience Behind Habit Formation
Our brains are intricate networks of neural connections, constantly adapting and rewiring through a phenomenon known as brain plasticity. This incredible ability allows us to shape our habits over time by consistently repeating behaviors.
In the beginning, forming a new habit may require conscious effort and intention, like setting a resolution. But as you persist, your brain embraces efficiency, and the once-conscious actions transform into unconscious routines, guiding you effortlessly through daily tasks.
In this post, we first explore how habits are formed and then the neurological processes behind them. On top of that, we provide practical strategies to help you create lasting habits in various aspects of your life. And why not stop some of them that are toxic?
Neuroscience Basics to Understand Habit Formation
Neural Circuits and Brain Areas
Habit formation is closely linked to specific neural circuits in the brain. The basal ganglia, a group of nuclei located deep in the brain, is a central player in habit formation. The basal ganglia helps encode repetitive behaviors and routines, allowing them to become automatic over time. It’s involved in the transition from goal-directed actions (more conscious and effortful) to habitual actions (more automatic).
Habit formation relies on synaptic plasticity, which refers to the ability of synapses (the connections between neurons) to change in strength based on their patterns of activity. Repeated engagement in a specific behavior strengthens the synaptic connections between neurons that are involved in that behavior. This strengthening is a key mechanism underlying the formation and reinforcement of habits.
Dopamine and Reward Pathways
The brain’s reward system, which includes dopamine-producing neurons, plays a critical role in habit formation. When you engage in behavior that leads to a positive outcome or reward (such as a pleasurable feeling or relief from discomfort), dopamine is released. This release of dopamine reinforces the neural connections associated with the cues and routines that led to the reward. Over time, the brain learns to associate the cue with the reward and the routine, making the behavior more habitual.
The transition from Goal-Directed to Habitual Behavior
Initially, when you’re learning a new behavior, it’s more goal-directed. The prefrontal cortex, a region involved in decision-making and planning, is heavily engaged in this stage. However, with repetition, as the habit becomes established, the prefrontal cortex’s involvement decreases, and the basal ganglia takes over. This transition from a conscious effort to automaticity is a hallmark of habit formation.
Role of Context and Environmental Cues
Habits are often triggered by specific cues in the environment. These cues can be external (like seeing a particular object) or internal (like feeling a certain emotion). The brain learns to associate these cues with the routine and the reward. This association is stored in neural pathways, making it more likely that the cue will trigger the habitual behavior.
Habit Formation: Explained!
Habit formation typically involves a loop between three key components: the cue (or trigger), the routine (the habitual behavior itself), and the reward (the positive outcome that reinforces the behavior). This loop is often referred to as the “habit loop,” and it’s a concept popularized by Charles Duhigg in his book “The Power of Habit.”
- Cue (Trigger): This is the signal that initiates the habit. It can be an external stimulus or an internal feeling. For example, if you’re trying to develop a habit of exercising, the cue might be seeing your workout clothes, feeling stressed, or a specific time of day.
- Routine (Behavior): This is the habitual behavior itself that you engage in when the cue occurs. It’s the action you take in response to the trigger. Continuing with the exercise example, the routine would be the physical activity you perform as part of your exercise routine.
- Reward: This is the positive outcome that follows the routine and reinforces the habit. It’s the “feel good” experience that your brain associates with the behavior. In the case of exercising, the reward might be the release of endorphins, a sense of accomplishment, or a stress reduction.
But what really happens in the brain during these phases?
During the procedure which involves the habit loop (Cue – Routine – Reward), several things happen in the brain.
- Cue (Trigger):
- Brain Regions: The prefrontal cortex and relevant sensory processing areas are activated when the cue is perceived. These regions help recognize the cue and its significance.
- Neural Pathways: The brain forms associations between the cue and the anticipated behavior (routine) that follows. The basal ganglia, a region involved in habit formation, is particularly important for storing these associations.
- Neurotransmitter Involvement: The cue may trigger the release of dopamine in response to the anticipation of the forthcoming reward. This helps reinforce the connection between the cue and the routine.
- Routine (Behavior):
- Brain Regions: The prefrontal cortex, which is involved in decision-making and planning, is initially engaged when you consciously decide to perform the routine in response to the cue. Over time, as the habit becomes more ingrained, the involvement of the prefrontal cortex decreases, and the basal ganglia takes over.
- Neural Pathways: Repeated engagement in the routine strengthens the neural connections within the basal ganglia and other relevant areas, making the behavior more automatic.
- Neurotransmitter Involvement: The routine may trigger the release of dopamine, which contributes to the sense of satisfaction associated with the behavior.
- Brain Regions: The nucleus accumbens, a key part of the brain’s reward system, is activated when the reward is experienced. This region plays a central role in processing rewarding stimuli and reinforcing behaviors.
- Neural Pathways: The reward reinforces the neural pathways associated with the cue and the routine. This strengthening of synaptic connections makes the habit more likely to be repeated in the future.
- Neurotransmitter Involvement: Dopamine is released during the rewarding experience, providing a sense of pleasure and reinforcing the link between the cue, routine, and the positive outcome.
As a result…
Over time, with repetition, the habit loop becomes more efficient, and the involvement of conscious decision-making (prefrontal cortex) diminishes. The habit becomes automatic, and the anticipation of the reward (dopamine release) in response to the cue drives the behavior (routine). This process explains how habits become deeply ingrained in daily life.
Create New Habits – Break The Old!
Now that we understand the neuroscience behind habit formation, we can apply this knowledge to create new habits and break free from old ones. By leveraging the brain’s remarkable plasticity and the habit loop, you can kick-start lasting changes in your daily routines. Here’s how:
1. Identify Cues:
To create new habits, start by identifying cues that trigger the behavior you want to establish. These cues can be specific times of day, environmental cues, emotional states, or any other signals that prompt you to take action.
For example, if you want to develop a habit of reading daily, you can use cues like setting a specific time for reading or placing a book on your nightstand.
Do you want to eat healthier? Keep some washed green apples next to the sink or on the kitchen table. They will be in front of you every time you go to the kitchen. And they will be already washed, so you grab one without any friction!
2. Define Routines:
Once you’ve identified the cues, define the routines you want to establish in response to those cues. Be clear about the specific actions you’ll take. If your goal is to exercise, outline the type of exercise, duration, and any other details. The routine should be manageable and aligned with your goals.
Also, it is very important to set the when and the where. Define clearly the place, the time, and the exact action you will take.
‘On Monday at 7 p.m, I will run for 20 minutes in the park by my house.‘
Being precise on where, when, and what, increases the chances to engage in the activity.
3. Choose Meaningful Rewards:
Associate meaningful rewards with your new habits. These rewards can be intrinsic (such as a sense of accomplishment) or extrinsic (like treating yourself to something enjoyable).
Rewards reinforce the habit loop, making it more likely that you’ll repeat the behavior in the future. It’s so simple:
Behavior -> Enjoy the reward -> Repeat the behavior to enjoy the reward.
So, after a workout, you could treat yourself to a healthy snack or enjoy a relaxing break. This going to associate your effort with a positive feeling that will increase the chances to repeat the behavior.
4. Start Small and Be Consistent:
Begin with small, manageable steps to create a sense of accomplishment and build momentum. Don’t create huge expectations that will disappoint you and drown you down in the process.
Always remember: Consistency is key!
Aim to repeat the routine consistently, even if it’s in a modest form, to reinforce the habit loop. As you progress, you can gradually increase the complexity or duration of the routine.
P.S: As a personal experience, I can share this. I completely changed my body and my athletic ability by starting SMALL. How? I was a lazy weak guy. I started my journey to exercise by going to the gym ~3 times per week. In the beginning, I would never engage in extra difficult exercises or heavy schedules. I would seek to just be a little stronger month to month, season to season. Sure, I learned this the hard way after some disappointments of my time-to-time high expectations. But now I KNOW: Consistency is the key! Consistency made me fall in love with exercise. Consistency made me fall in love with the progress. And eventually, consistency gave me and still does, the results that reinforce again and again my exercise habits. I, currently, enjoy exercising 6 times per week and I am a completely changed man!
5. Replace Old Habits:
To break old habits, you can use a technique known as “habit replacement.” Identify the cues that trigger the unwanted habit and replace the routine with a healthier alternative. For instance, if you’re trying to quit snacking on unhealthy foods, replace the routine of reaching for chips with the routine of grabbing a piece of fruit.
What will eventually happen is that your old bad habit will be replaced by a new one. Instead o a cigarette, you might look for an apple.
6. Mindful Awareness:
Cultivate mindful awareness of your habits and their underlying cues. Recognize the moments when the habit loop is initiated. When you’re aware of the cue, you can make a conscious decision to engage in the desired routine and receive the associated reward.
7. Patience and Persistence:
Changing habits takes time, and setbacks may occur. Be patient with yourself and stay persistent. If you slip up, acknowledge it, learn from it, and recommit to your desired habit. Celebrate your successes, no matter how small, as they reinforce positive associations.
As we already discussed, consistency is the key. And in order to be consistent you need to be patient and persistent. I promise the results will follow!
8. Create a Supportive Environment:
Set up your environment to support your new habits and discourage old ones. Remove temptations that trigger unwanted behaviors and create reminders for your desired routines. Surround yourself with positive influences that align with your goals.

As James Clear, the writer of the bible for habit formation, the bestseller book Atomic Habits says: ‘Motivation is Overvalued. Environment Often Matters More.‘
Change your habits – Change your life
In the intricate dance of our brains, habits are the choreography that shapes our lives. In the end, we are our habits!
Now, Armed with the knowledge, you hold the key to change. You can harness the power of neural plasticity to create new habits that align with your goals and aspirations. You can also break free from the clutches of old habits that no longer serve you.
It’s a journey of self-discovery and self-mastery, and it requires patience, persistence, and mindful awareness. You now understand the magic of small consistent actions, the motivation behind rewards, and the dance between the prefrontal cortex and the basal ganglia. With each deliberate step you take, with each moment of mindful recognition, you’re sculpting the pathways of your brain. You are paving the way for a better, healthier, and more fulfilling life.
Remember, change takes time, and setbacks may occur along the way. So keep on!
