Basal Ganglia

The habit center of the brain.  The basal ganglia is central to your automatic habitual actions and ways of thinking.  Two of its major structures are the caudate and the patumen.[i]  Another important component of the basal ganglia is the nucleus accumbens which plays a critical part of our reward system.

According to some neuroscientists “about 80 percent of the neural instructions for behavior are recorded in implicit memory, outside our conscious awareness.”[ii] Neurologically habits work in a loop that contains a cue, routine, and reward.  What makes up our habits is often outside of our conscious awareness.  Isolating the cue, routine and reward of a habit can help us see why we do the things we do.  Often there is a trigger that sends our minds into automatic mode.  Imagine a commercial of an ice-cold beverage or a mouth-watering sandwich.  Those are powerful cues that impel us to act.  Our routines can be emotional, physical or psychological.  It could be a thought pattern or something like going to the refrigerator late at night.  The reward is something that your brain uses to remember this pattern even without thinking.  Our memories are encoded with emotional content that will produce real feelings of euphoria or disgust.  When you isolate the reward, it can help to change the routine.  The fruit of the spirit produces treasures of love, joy, and peace within us.  If we take the time to cultivate and reward ourselves through God’s goodness, our habit center will help us more automatically choose God’s will for our lives, rather than destructive habits and behaviors.

The striatum groups together several other parts of the basal ganglia and is its largest structure. The striatum includes the nucleus accumbens, putamen, and caudate. It inhibits the activity of the amygdala.  It also allows you to feel safe in the presence of God.[iii]
