Tentorium, Migraines and Unresolved Trauma

The tentorium cerebelli is a crucial structure in the brain that separates the cerebellum from the cerebral hemispheres. It is a tough, tent-shaped membrane that runs horizontally around the back of the skull. While it serves to protect and support the brain, it can also be an indicator of underlying tension and trauma. When the tentorium cerebelli is tight, it can cause various symptoms, such as headaches, neck pain, and dizziness. These symptoms may be related to chronic stress and trauma, as the body responds to these experiences by holding tension in various areas, including the tentorium cerebelli.


Understanding the connection between the tentorium cerebelli and chronic stress and trauma can be crucial in addressing these issues. By identifying and releasing tension in this area, individuals may be able to alleviate symptoms and improve their overall well-being. It may also be helpful to seek support from healthcare professionals who specialize in trauma-informed care and mind-body therapies.




What is the tentorium?

The tentorium cerebelli is a double-layered membrane located at the back of the cranium, approximately in line with the top of the ears. It separates the cerebrum from the cerebellum and acts as a tent-like structure over the top of the cerebellum.

This membrane attaches to various major cranial bones, such as the occipital bone, the petrous portion of the temporal bones, and the occiput, parietal, and clinoid processes of the sphenoid, as well as the falx cerebri. This is significant because any tension or damage to the tentorium can affect the mobility of these bones, and vice versa.

Additionally, the tentorium has a close relationship with the sinuses, particularly the straight sinus and sigmoid sinus. Furthermore, the tentorium is responsible for transmitting information about neck and head movements to the central nervous system through the cervical tract. When the tentorium is tight or damaged, it can impact the transmission of messages through the brain stem.


Chronic stress, especially when attempting to manage one's environment or emotions, can result in tension throughout the body, including the tentorium. This tension can cause pain and discomfort, comparable to a tightly stretched rubber band, which can be easily damaged or cause pain with even the slightest activation or tension. It's essential to prioritize self-care and take measures to relieve tension to avoid discomfort and maintain a healthy body.



What does the Tentorium feel like?

When experiencing persistent stress, tension headaches, or neck tension, the impact on the tentorium cerebelli can often be felt through touch at the back of the skull above the occipital basel. In these cases, the tentorium may feel like a thick rubber band that has been stretched, rather than a soft and adaptable tissue. This thickening of the membrane is the result of the load it has had to bear and its need to offer support. However, this can lead to increased cranial pressure, decreased mobility in the temporal area, and tension in the cervical spine.




What does the Tentorium do?

  • Protection: The tentorium cerebelli acts as a barrier, protecting the brain from shock and injury. It provides a tough, tent-like structure that separates the cerebrum from the cerebellum, shielding the brain from potential damage caused by external forces.

  • Pressure Regulation: The tentorium cerebelli helps to regulate the pressure within the cranium, which is crucial for the proper functioning of the brain. It plays a critical role in the flow of cerebrospinal fluid, which is necessary for maintaining neurological health.

  • Structural Integrity: The tentorium cerebelli is an essential component of the membrane system that supports the brain. It helps to maintain the structural integrity of this system, which is necessary for the proper functioning of the brain.

  • Communication: The tentorium cerebelli communicates mechanical, neurological, and sensory imprints through the body. This is because there is a plexus, a group of nerves that acts like a control center, within the membrane. The plexus carries rich information that allows the tentorium to adapt to incoming stimuli, including pressure and movement. This communication helps to coordinate movements and sensory information throughout the body.

The tentorium cerebelli plays a critical role in protecting the brain, regulating pressure within the cranium, maintaining the structural integrity of the membrane system, and communicating sensory information throughout the body.


Understanding the Relationship between Tension in the Cranium, Cerebrospinal Fluid Production, and Nervous System Functioning

Fluid flow and pressure are closely related. As the pressure within the cranium increases due to tension in the membranes, the body tries to reduce the production of Cerebrospinal (CSF) to balance the pressure. Conversely, if the pressure in the cranium is too low, the body may increase the production of CSF to maintain the pressure.


When tension is held in the cranial membranes, it can directly impact the production of CSF, which, in turn, affects the entire nervous system functioning. The production and circulation of CSF are crucial for the proper functioning of the central nervous system, as it helps to nourish and protect the brain and spinal cord. Therefore, understanding the relationship between tension in the cranium, CSF production, and the functioning of the nervous system is crucial for maintaining optimal health and well-being.


By releasing tension through somatic release, craniosacral therapy and energy work, individuals may be able to improve the production and circulation of CSF and enhance the functioning of the nervous system.


The Mind-Body Connection: Exploring the Relationship Between Stress, Movement, and the Tentorium Cerebelli

Stress can have a profound impact on our bodies, changing the way we move, breathe, and even our posture. The tentorium cerebelli, a double-layered membrane at the back of the cranium, has a close relationship with the neck, which can affect the flow of fluid in the nervous system. Nerve fibers from the superior cervical ganglion in the neck provide sympathetic innervation to the tentorium, making it highly sensitive to movement and postural changes.


Various factors can impact how we move our head and neck, including our perception of our surroundings, how we move in space, and the condition of our body. The quality of the tentorium also relates to what we see and hear. The tentorial nerve, also called the Nerve of Arnold, is a branch of the ophthalmic nerve that supplies the tentorium. If we strain our vision or are exposed to loud, violent sounds, the tentorial and tentorium can have a neurological response, affecting the quality of the tentorium.


To maintain the health of the tentorium and the nervous system overall, it's important to be mindful of our movements, take breaks from screen time, and protect our senses from harsh stimuli. By paying attention to our bodies and taking steps to reduce stress and tension, we can help support the health of the tentorium and the nervous system.




The Impact of Childhood Trauma on the Tentorium Cerebelli: Understanding the Relationship between Stress, Movement, and Sensory Processing

Growing up in a traumatic environment as a child can have a profound impact on one's physical and emotional health, including the quality of the tentorium cerebelli.

Traumatic experiences can create chronic stress responses in the body, which can lead to persistent tension and changes in movement patterns. These changes in movement can impact the quality of the tentorium, affecting its ability to transmit sensory information through the nervous system. Additionally, exposure to loud, violent sounds or constant sensory overload can further exacerbate tension in the tentorium, impacting its overall health.


Furthermore, trauma can also impact the development of the nervous system, including the formation of neural pathways that govern movement and sensory perception. This can lead to changes in movement patterns and sensory processing that persist into adulthood.


Therefore, addressing the impact of childhood trauma on the tentorium and nervous system functioning is crucial for promoting overall well-being. Mind-body practices, such as meditation, yoga, and somatic therapies, can be helpful in releasing tension in the tentorium and promoting relaxation and healing.



Exploring the Benefits of Releasing Tension in the Tentorium Cerebelli

  1. Improve neck mobility: Releasing tension in the tentorium can improve neck mobility by reducing restrictions in the cervical spine. This can alleviate neck pain, stiffness, and headaches caused by tension in the neck muscles.

  2. Reduce cranial pressure/tension: Chronic tension in the tentorium can increase pressure within the cranium, which can cause headaches and other discomfort. Releasing tension in the tentorium can alleviate this pressure and reduce tension in the surrounding structures.

  3. Eliminate vascular headaches: Vascular headaches, such as migraines, are often caused by tension in the blood vessels of the head and neck. Releasing tension in the tentorium can help to alleviate this tension and reduce the frequency and severity of vascular headaches.

  4. Improve sinus function: The tentorium has a close relationship with the sinuses, particularly the straight sinus and sigmoid sinus. Releasing tension in the tentorium can improve the flow of cerebrospinal fluid and lymphatic fluid, which can help to alleviate sinus pressure and improve sinus function.

  5. Support lymphatic flow: The tentorium contains a network of lymphatic vessels that help to remove waste and toxins from the brain. Releasing tension in the tentorium can support lymphatic flow and help to remove waste products from the brain more efficiently.




The Benefits of Craniosacral Therapy and Somatic Integration for Restoring Tentorium Flexibility and Promoting Nervous System Health

By engaging with the tentorium through gentle touch and subtle pressure, a craniosacral therapist can release tension, increase tone, and restore flexibility to the membrane. This can result in the expansion of the cranium and the widening of the brain, dural membranes, and cranial bones.


Additionally, the spine and dural tube can lengthen, promoting the flow of fluid and drainage of cerebrospinal fluid, which supports the glymphatic system's ability to carry fluids away from the brain. Clients often report experiencing a sense of relief and relaxation, as well as a feeling of expansion or becoming heavier.


Restoring the tentorium to its supple and supportive role can also increase freedom and flexibility in the cranial bones and other membranes, such as the falx cerebri, which can have a beneficial effect on the sinus system.




The Interconnectedness of the Tentorium, Neck Mobility, and Overall Well-Being: A Holistic Perspective

The connection between head and neck movement, the nervous system, and the efficiency of the lymphatic system is well-established in the craniosacral model, as well as in other holistic bodywork practices such as yoga. As everything we feel has a physical response in the body, our membrane system holds on to these responses. However, through cranial work, it is possible to release persistent shock and tension, as well as old chronic injuries, relatively easily. This is because our membrane system is particularly receptive to help us restore and maintain balance and harmony in our body, promoting overall health and well-being. By prioritizing the health and mobility of the neck, individuals can support their lymphatic and nervous systems, and promote optimal functioning of the body as a whole.
