Our lower brain is the oldest evolutionary part of our minds. The lower brain is responsible for unconscious body control like breathing, swallowing, and instincts/reflexes like crawling, suckling, walking, relaxing and overall understanding of where our bodies end and the world begins.
When any one of these reflexes is inefficiently integrated it can take processing power from the cortex to compensate. This inefficiency can result in nail-biting, being unathletic, and trouble relaxing, walking and even driving or riding a bike!
Here are some reflexes for you to research that we can help integrate:
Common symptoms: Hyperactive then fatigued, hypersensitivity to senses (light, sound, touch, smell), unable to filter unwanted stimuli, hyperglycemia, poor balance
Fear Paralysis Reflex (FPR)
Common symptoms: Selective mutism, excessive anxiety, low tolerance to change, withdraws from touch, isolation/withdrawal, easily overwhelmed
Common symptoms: Clenching fists unconsciously, lack of fine and gross motor skills, lack of healthy boundaries, drooling, excessive chewing/nail biting, underdeveloped spatial awareness
Common symptoms: Clumsiness, "pigeon toed," walks on edges of feet or toes, difficulty walking and talking, foot cramps/clenching, multiple sprained ankles
Tonic Labyrinthine Reflex (TLR)
Common symptoms: Poor balance, fear of heights, walking on toes, unathletic movement, crossing eyes,
Asymmetrical Tonic Neck Reflex (ATNR)
Common symptoms: Dyslexia, difficulty riding a bike/balance/turning, poor handwriting, difficulty in tasks crossing the midline of the body
Symmetrical Tonic Neck Reflex (STNR)
Common symptoms: Slumped posture, difficulty reading/writing, excessive headaches, discomfort sitting, poor hand-eye coordination, poor vision
Common symptoms: Scoliosis, bedwetting past age 5/prolonged potty training, dislikes tight clothing, difficulty sitting still, inefficient short-term memory
