What is synesthesia?

What is synesthesia?

Synesthesia is a neurological phenomenon in which stimuli in one sensory modality involuntarily and consistently evoke other sensory experiences. For example, people with synesthesia may perceive sounds as moving colours or numbers and letters as specific tastes or textures. This particular phenomenon is not a mere curiosity, but provides insight into how our brains process information and how different brain regions interact. Research suggests that these experiences are not necessarily a 'disorder', but rather a different way of sensory integration that may be both genetic and environmental.

What causes synesthesia?

The origin of synesthesia remains a fascinating topic within neuroscience. Several studies suggest that synesthesia stems from increased connectivity between brain regions that normally operate separately. These atypical connections may be hereditary, but may also arise from unique environmental influences in early development. Moreover, the way neurotransmitters such as dopamine and serotonin functioning, contribute to the emergence of synesthetic experiences. The complexity of these interactions makes it a multifaceted research area where both genetics and biochemistry play an important role.

The neurochemistry of synesthesia

Understanding the neurochemistry behind synesthesia offers valuable insights into how our brains work. Neuroscientists point out that neurotransmitters play a crucial role in the transmission of information between neurons. In people with synesthesia, it appears that there may be a different balance in the release and reception of signals, leading to the unusual sensory cross-talk. When using psychedelic drugs, the action of certain receptors, especially those for serotonin, changes, which can result in a temporary reconfiguration of these sensory networks. This partly explains why some people experience synesthesia during a psychedelic experience.

Synesthesia and MDMA

MDMA, often associated with feelings of connection and emotional intensity, can also trigger synesthesic experiences in some users. The increased release of serotonin and altered signal processing in the brain seem to lead to a blending of sensory information. These effects are sometimes experienced as particularly intense and transformative, contributing to the therapeutic potency of MDMA in controlled environments. However, much research is still needed to fully understand the exact mechanisms and long-term effects of MDMA-induced synesthesia.

Synesthesia and psilocybin (truffles)

Psilocybin is known for opening up new perspectives in sensory perception. During a psilocybin experience colours, shapes and sounds can intertwine in unusual ways, leading to a rich palette of visual and auditory associations. These phenomena are not only appreciated by users for their aesthetic and emotional impact, but have also led to scientific research into the therapeutic applications of psilocybin. Studies suggest that the enhanced connectivity between brain regions can help break rigid thinking patterns, potentially contributing to positive psychological changes.

Synesthesia and LSD

LSD is another psychedelic known for inducing synesthesia. Users often report that sounds become colours and shapes seem to come to life. These experiences are caused by increased activity in areas of the brain that do not normally communicate directly with each other. This increased connectivity creates unusual and often stunning perceptual experiences. So far, it seems that LSD sessions cause most synesthesia.

History and research on synesthesia

Interest in synesthesia reaches far back and has a rich history in both art and science. Artists and musicians over the centuries have tried to capture the special sensory mixing that occurs with synesthesia in their work. Scientific research has further explored these experiences, leading to a better understanding of the underlying neural mechanisms. Through modern imaging techniques and genetic studies, there is growing evidence that synesthesia is a natural variation within human perception, giving us insight into the complexity of the brain.

Personal experiences

Within therapeutic practice, we regularly encounter people who, consciously or unconsciously, have had experiences with synesthesia. Some clients report that during psychedelic sessions with LSD or psilocybin, they gained new insights into their emotional and cognitive patterns thanks to this sensory cross-talk. These experiences, although very personal and individual, contribute to the growing realisation that synesthesia can be a valuable key to a deeper understanding of the human mind.

Triptherapie: support and guidance

At Triptherapie, we strive to harness the transformative power of psychedelic therapy in a responsible and professional manner. Our guidance is based on sound scientific evidence and years of experience in therapeutic practice. We understand that integrating experiences such as synesthesia, which can occur during psychedelic sessions, can be helpful if properly understood. Therefore, we offer extensive aftercare and individual counselling, so that the insights that emerge during these sessions can be constructively integrated into daily life. Our approach is always holistic and tailored to the unique needs of each client.
