When most people think about brain development in children, they think about language, learning, and emotional regulation. They think about the prefrontal cortex - the seat of executive function, decision-making, and impulse control.

What they don't think about is the cerebellum.

And that's a problem. Because the cerebellum is one of the most critical and most overlooked structures in child neurodevelopment - and a growing body of research suggests that cerebellar underdevelopment may be implicated in a wide range of issues that parents are told have nothing to do with the brain [and honestly? the cerebellum is one of my favourite brain areas to work with].

What Is the Cerebellum?

The cerebellum (Latin for "little brain") is a structure at the base of the brain, sitting just above the brainstem. Despite accounting for only about 10% of the brain's total volume, it contains more than 50% of all the neurons in the entire brain.

That alone tells you it's doing a lot of work.

For a long time, the cerebellum was considered exclusively a motor structure - responsible for coordination, balance, and fine motor control. And it absolutely does all of those things. But neuroscience has dramatically expanded our understanding of cerebellar function over the past two decades, and we now know that the cerebellum plays a significant role in:

Motor coordination and balance — the original and still central function
Timing and rhythm — the cerebellum is essentially the brain's internal clock
Sensory integration — processing and making sense of information coming in from the body and environment
Attention and focus — the cerebellum has direct connections to the prefrontal cortex and plays a role in sustained attention
Language and reading — cerebellar circuits are involved in the automatisation of language skills, including reading fluency
Emotional regulation — emerging research shows the cerebellum has connections to limbic structures involved in mood and emotional processing
Predictive processing — the cerebellum helps the brain predict what is about to happen (both physically and cognitively), allowing for smooth, anticipatory responses

The developing cerebellum

The cerebellum develops primarily after birth, making it particularly dependent on movement and sensory experience during early childhood.

Unlike some brain structures that develop rapidly in utero, the cerebellum continues its most rapid development through the first few years of life - and it develops in response to use. The more a child engages in varied, whole-body movement, the richer the neural connections within the cerebellum become.

This is why childhood is such a critical window for cerebellar development - and why changes to how children move (or, more accurately, how little they move today compared to previous generations) have such significant implications for neurological development.

In my practice, I do find that stressful pregnancies seem to influence cerebellar function too.. this is just a pattern I have noticed, that sets a child up for more tricky movement patterns in those first 3 years of life.

Signs That a Child's Cerebellum May Need Support

Cerebellar underdevelopment or dysfunction doesn't always look the way you'd expect. Yes, a child with poor balance and clumsy motor skills may have cerebellar involvement. But so might a child who:

Struggles to read fluently — particularly if they read word by word rather than with flow, or lose their place frequently
Has difficulty with handwriting — whether in terms of letter formation, spacing, pressure, or speed
Is easily distracted or struggles to sustain attention — given the cerebellum's connections to frontal attention networks
Has poor rhythmic sense — difficulty clapping in time, following a beat, or anticipating sequences
Struggles with sequencing — in tasks, in language, in organising their thoughts
Has poor proprioception — an unclear sense of where their body is in space, leading to bumping into things, poor spatial awareness, or difficulty with ball skills
Is emotionally dysregulated — given the cerebellum's emerging role in emotional processing
Experiences motion sickness — which reflects difficulty integrating vestibular (balance) and visual input, a classic cerebellar function
Has retained primitive reflexes — many primitive reflexes that should integrate in infancy are governed by cerebellar maturation

If several of these resonate, it is worth considering the cerebellum as part of the picture — alongside any other assessments that may be underway.

The link between the cerebellum and learning difficulties

This is where the research gets particularly interesting for parents of children with learning or attention challenges.

Dr Harold Levinson, a psychiatrist and neurologist, was one of the pioneers in identifying cerebellar-vestibular dysfunction as a contributing factor in dyslexia and learning difficulties. His work proposed that many of the core difficulties in dyslexia (particularly with reading automaticity, letter reversals, and sequencing) reflected an underlying cerebellar issue rather than purely a cortical one.

More recently, neuroimaging studies have confirmed that the cerebellum shows differences in children with dyslexia, ADHD, and autism spectrum conditions. Cerebellar connections to the prefrontal cortex — the "cerebellar-prefrontal loop" — are particularly implicated in ADHD, with some researchers proposing that cerebellar timing deficits may underlie the difficulty with self-regulation and executive function that characterises the condition.

This does not mean the cerebellum is the only factor, these conditions are complex and multifactorial. But it does mean that cerebellar support should be part of the conversation.

What is cerebellar training?

Cerebellar training refers to activities and exercises specifically designed to stimulate and develop the cerebellum. Because the cerebellum develops through movement and sensory input, cerebellar training is almost always movement-based, but it's a specific kind of movement.

The cerebellum responds best to:

Rhythmic, repetitive movement Activities that involve rhythm (bouncing, jumping, clapping, marching, dancing) stimulate the cerebellar circuits involved in timing and sequencing.

Balance and vestibular challenges Activities that challenge balance and engage the vestibular system (the inner ear system that detects head position and movement) directly stimulate cerebellar circuits. Think balance beams, wobble boards, trampolines, spinning, rolling, and cartwheels.

Cross-lateral movement Movements that cross the midline of the body (where the right arm and left leg move together, or the eyes track across the visual midline) stimulate communication between the two hemispheres of the cerebellum and promote integration.

Fine motor challenges Activities requiring precision and dexterity (catching and throwing, threading, building, drawing) engage the cerebellar circuits involved in motor planning and timing.

Dual-task activities Activities that require the child to do two things simultaneously (balance while catching a ball; march while counting) create the most powerful cerebellar stimulus, because the cerebellum must coordinate multiple streams of input.

Eye tracking and visual-motor integration Tracking a moving object, following a line, or engaging in activities that require visual-motor coordination all stimulate cerebellar pathways involved in smooth eye movement (saccades and smooth pursuit).

If you have a child who is high needs, and some of these activities are just not possible, I like to start with sensory input from the body. My favourite way being the Rezzimax (click this blog link for a discount code!).

The role of primitive reflexes in cerebellar development

One area worth mentioning here is the relationship between retained primitive reflexes and cerebellar development.

Primitive reflexes are the automatic movements present at birth that should integrate (become inhibited and absorbed into voluntary movement) during the first year of life. This integration is largely a function of cerebellar and cortical maturation.

When primitive reflexes are retained past the age they should integrate, it is often a sign that the cerebellum has not fully matured. And the retained reflexes themselves can continue to interfere with higher-level neurological development - creating a cycle where cerebellar underdevelopment perpetuates reflex retention, and reflex retention perpetuates cerebellar underdevelopment.

Assessing and addressing retained primitive reflexes (through specific movement programmes) is a key component of cerebellar rehabilitation in children.

Why modern childhoods are shortchanging the cerebellum

It's worth pausing here to acknowledge something important: many children today are simply not getting the movement their cerebellum needs to develop properly.

Previous generations of children spent hours each day in unstructured outdoor play - climbing trees, rolling down hills, spinning on merry-go-rounds, building dens, playing rough-and-tumble games. All of this was, neurologically speaking, simple and high-value cerebellar stimulation.

Today's children spend significantly more time in sedentary, screen-based activities. They are transported rather than walking. Their play is increasingly structured and sedentary. School involves long periods of sitting.

The cerebellum, which depends on movement to develop, is being under-stimulated during the most critical window of its development. This is not a moral judgement - it is a neurological reality that has significant implications for children's development, learning, and emotional regulation.

The answer is simple, though not always easy: children need to move. A lot. In varied, challenging, whole-body ways.

And I know, many kids with struggles are moving a lot, that increased movement does not fix everything. But a child who seeks movement is trying to stimulate their cerebellum. A child who avoids movement likely knows the cerebellum will get overwhelmed by the movement. The way your child moves is also information as to how their nervous system is currently wiring and functioning.

What parents can do

The good news is that cerebellar training doesn't require expensive equipment or specialist clinics. Many of the best cerebellar activities are also the most enjoyable for children:

Trampolining — excellent vestibular and cerebellar stimulation
Climbing — challenges balance, proprioception, and motor planning
Dancing and martial arts — rhythm, cross-lateral movement, sequencing
Ball sports — visual-motor integration, timing, prediction
Swimming — whole-body coordination in a challenging sensory environment
Skipping and hopscotch — rhythm, coordination, sequencing
Gymnastics and tumbling — balance, spatial orientation, motor planning
Rough-and-tumble play — proprioceptive and vestibular input
Balance-based activities — balance boards, slacklining, walking along low walls

For children with more significant developmental concerns, a structured cerebellar training programme (guided by a practitioner who understands neurological development) can make a meaningful difference.

The chiropractic connection

From a chiropractic perspective, the cerebellum is of particular interest because of its close anatomical relationship with the upper cervical spine and the brainstem.

The cerebellum sits directly above the brainstem, which passes through the foramen magnum at the top of the cervical spine. The proprioceptive input from the joints of the upper cervical spine (particularly C1, C2, and C3) is one of the most significant inputs to the cerebellum. In fact, the upper cervical spine sends more proprioceptive information to the cerebellum than almost any other region of the body.

This means that dysfunction in the upper cervical spine, which can occur following birth trauma, falls, or postural stress, may directly affect the quality of information reaching the cerebellum, and therefore cerebellar function itself.

Chiropractic assessment and care in children often involves a thorough evaluation of cervical spine function, with the understanding that optimal spinal mechanics are part of the foundation for optimal cerebellar and therefore neurological development.

However.. I would recommend finding a chiropractor who understands the neurology underneath.

A final note for parents

If you're reading this because something about your child's development has been niggling at you (their clumsiness, their reading, their attention, their emotional regulation) I want you to know that your instinct is worth following.

The cerebellum is a powerful piece of the neurodevelopmental puzzle that is often missed. It is not the whole story, but for many children, it is a significant part of it. And it responds remarkably well to the right kind of input.

Children's brains are plastic - they are designed to grow and change. It is never too late to provide the stimulation the cerebellum needs to develop more fully.
