Neurology of New Routines

The Simple Science

When you’re trying to adapt to new routines, whether it’s a new job or another significant life change, understanding the neurology behind habit formation can be incredibly helpful. Essentially, your brain forms pathways based on repeated behaviors; these are like well-worn paths in a forest, easy to travel because they’re familiar. When you start a new routine, it’s like blazing a new trail through the woods—it’s tougher and requires more effort.

To make this work for you, begin by establishing small, manageable habits that align with your new routine. Let’s say you’re starting a new job and want to maintain a fitness routine. Instead of aiming for big goals, like hour-long workouts every day, start with something small, like a 15-minute workout in the morning or a walk during your lunch break. Consistently doing these smaller activities helps lay down new neural pathways, making the behavior feel more automatic over time.

Additionally, keep in mind that repetition is key. The more you repeat an activity, the stronger and more automatic the neural pathway for that activity becomes. So, sticking to your new small habits consistently is crucial. Over time, these new trails become easier to travel, and the routine feels like a natural part of your day.

The Deeper Learning

The neurology of new routines revolves around how the brain adapts to and reinforces new behaviors, fundamentally altering neural pathways through a process called neuroplasticity. This concept is central to understanding how we can effectively form new habits or adapt to new routines.

Neuroplasticity

Neuroplasticity refers to the brain’s ability to reorganize itself by forming new neural connections throughout life. This plasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment.

Formation of Neural Pathways

When you engage in a new activity or routine, your brain begins to form and strengthen pathways that support this behavior. Neurons communicate with each other through synapses (points of contact where neurotransmitters are released to stimulate other neurons). When a behavior is repeated, the synaptic connections between neurons strengthen. This is encapsulated in the neuropsychological maxim: “Neurons that fire together, wire together.” This process enhances the efficiency of signal transmission along these pathways, making the behavior easier and more automatic—a principle known as synaptic plasticity.

Role of the Basal Ganglia

The basal ganglia, a group of structures located deep within the cerebral hemispheres, play a crucial role in the development of new habits and routines. They are involved in the control of voluntary motor movements, procedural learning, routine behaviors, and emotions. When a new routine is practiced consistently, the basal ganglia help to automate it, reducing the cognitive effort needed to carry out the activity. This is why after repeated practice, activities like driving a car or playing an instrument can be performed almost automatically.

Involvement of the Prefrontal Cortex

Initially, when a new routine is being established, the prefrontal cortex—the area of the brain responsible for executive functions such as planning, decision-making, and moderating social behavior—is heavily involved. It helps you to consciously control your actions and make decisions about new behaviors. Over time, as the routine becomes more ingrained, the reliance on the prefrontal cortex decreases, and the behavior becomes more automatic, shifting control to the basal ganglia.

Impact of Stress and Emotions

The amygdala, which processes emotions, also influences how new routines are formed. Emotional states can affect the strength and retention of new habits. Positive emotions can enhance the learning of new routines, while stress and negative emotions might impair habit formation by activating the hypothalamic-pituitary-adrenal (HPA) axis and releasing stress hormones like cortisol, which can interfere with cognitive processes and synaptic plasticity.
