[Solved] How important is neurochemistry in psychedelic sessions?

At psychedelic therapy You might first think of the colorful visuals, profound insights, and the sense of oneness with the universe. But behind those impressive experiences lies a fundamental biological system that controls everything: the neurochemistry of your brain. Inside Triptherapie This neurochemistry forms the basis of every session — from preparation to integration.

In this blog, we dive deeper into the role of neurotransmitters such as serotonin, dopamine, GABA, glutamate, and oxytocin, and show how optimizing your neurochemical balance can make the difference between a chaotic experience and a deep, healing journey.

🔬 The biochemical effects of psychedelics

Most classic psychedelics — including psilocybin, LSD, and DMT — primarily affect the serotonergic system. The active substance psilocin (derived from psilocybin) binds to 5-HT2A receptors in the cerebral cortex. This activation leads to:

Altered sensory perception (visual, auditory, tactile)
Reduction of the ego (sense of merging with the environment)
Increased neuroplasticity, which creates space for behavioral change and healing

A crucial network that is affected by this is the Default Mode Network (DMN), which is responsible for self-reflection, the 'inner voice', and habitual thoughts. Psychedelics temporarily dampen the activity of this network, creating space for openness, emotional processing, and new insights.

🧪 The role of specific neurotransmitters

1. Serotonin – the bridge to connectedness

Serotonin is the primary target substance of classic psychedelics. Psilocin activates serotonin receptors and partially mimics their action. However, when the serotonin system is out of balance—for example, due to a tryptophan deficiency or underlying inflammation—the session can be less effective or even chaotic.

At Triptherapie prior to the session, we look at this balance via a intake with neurotransmitter test. We recommend foods and supplements that support serotonin and work on lowering inflammation levels. Because: more available serotonin = a greater chance of connection, love, and deep healing during the session.

2. GABA – inner peace as a foundation

GABA is the most important inhibitory neurotransmitter and acts as a natural counterpart to glutamate. Too little GABA can lead to insomnia, anxiety, or panic attacks — especially during a psychedelic trip. Therefore, we often recommend L-theanine, magnesium, and breathing techniques to strengthen the GABA system. This helps the brain stay calm during intense sessions.

3. Dopamine – motivation and integration power

Dopamine regulates motivation, focus, and feelings of reward. During the session, it supports your curiosity and perseverance. In the days and weeks afterward, dopamine plays a key role in the integration phase: are you able to translate insights into action? Through supplementation and behavioral interventions, we strengthen this dopamine system beforehand, ensuring that you not only go deep during your session but also truly change afterward.

4. Glutamate – sparks of change

Glutamate is involved in learning and memory. During a session, glutamate activity increases, which — together with an increase in BDNF (Brain-Derived Neurotrophic Factor) — leads to increased neuroplasticity. This allows new neuronal connections to form. It is this temporary state of heightened brain flexibility that makes psychedelics so effective for depression, addiction, or trauma.

5. Oxytocin – connection, safety, healing

Oxytocin is primarily released during sessions with MDMA or an MDMA analogue. This substance increases feelings of trust, closeness, and emotional openness. In therapy, this is invaluable: it allows you to dare to show your true self, relive old pain without panic, and view relationships with compassion. MDMA-based therapy makes smart use of this oxytocin boost to heal traumas.

💊 Medication, supplements, and risks

Neurochemistry also determines which substances you can safely combine. SSRIs, for example, inhibit the effects of psychedelics by blocking 5-HT2A receptors. MAO inhibitors can even cause life-threatening interactions — especially in combination with psilocybin or MDMA. Therefore, we always screen for medication use during the intake and provide tapering advice if necessary.

Also be careful with serotonergic supplements such as 5-HTP or L-tryptophan right before or after a session — excessive use of these can lead to serotonin syndrome, a rare but serious condition.

🧘‍♀️ Biology and experience: the synergy

Neurochemistry lays the foundation, but the experience arises in the interaction between biology and experience. Increased serotonin activity *can* lead to feelings of unity, but whether that actually happens depends on your intention, mindset, guidance, and environment. At Triptherapie we combine both: we ensure an optimal neurochemical climate and a warm, safe setting.

✨ Conclusion: neurochemistry as the foundation of healing

Neurochemistry is not a detail, but a foundation of psychedelic therapy. By consciously working on the balance of serotonin, dopamine, GABA, glutamate, and oxytocin, we create at Triptherapie the ideal conditions for healing. In combination with personal guidance, psychological integration, and a safe environment, a unique opportunity arises: sustainable transformation based on science and soul power.

Neurochemistry is, in fact, the fundamental basis of a psychedelic experience. Psychedelic substances directly alter chemical signaling in the brain, and with it, the activity of brain networks involved in emotions, perception, meaning-making, and the sense of self. Without this biochemical change, the typical psychedelic state would simply not occur.

When someone uses psilocybin, this substance is converted into psilocin in the body. Psilocin then binds to serotonin receptors, particularly the 5-HT2A receptor. Activation of this receptor alters communication between brain regions and temporarily disrupts the normal organization of neural networks. As a result, patterns of thinking and feeling can become looser, connectivity between different brain regions increases, and the so-called default mode network, which is involved in a stable self-image, can temporarily become less dominant. These are neurochemical and neurophysiological processes that form the basis for phenomena such as intense emotions, new perspectives, ego blurring, and visual changes.

The fact that neurochemistry The central role it plays becomes clear when looking at other substances that influence the brain. An injection of adrenaline or a sharp rise in cortisol changes a person's psychological state almost immediately. A person becomes more alert, experiences more tension or threat, and reacts differently to their environment. The same applies to changes in dopamine, serotonin, or testosterone. These examples show that changes in chemical signals in the body often lead directly to changes in feelings, behavior, and cognition.

Something similar happens during psychedelic sessions, but involving specific receptors and brain networks responsible for perception, meaning-making, and self-reflection. The substance therefore first alters the neurochemical state of the brain. From this new state, the subjective experiences people have during a session subsequently arise.

However, this does not mean that psychology or environment are unimportant. The neurochemical change creates, as it were, a state in which the brain becomes more flexible and sensitive to internal and external stimuli. In that state, memories, emotions, and insights can surface more easily. Exactly what content emerges is influenced in part by personal history, expectations, intentions, and the environment in which the session takes place.

The most accurate conclusion is therefore that neurochemistry forms the basis of the psychedelic state, while psychological factors and the setting determine how that state manifests concretely. The chemistry opens the window of an altered state of consciousness, and within that window, the psyche and context determine which experiences and insights arise. For this reason, preparation for a psychedelic session is important—and not just the psychological preparation, but especially the neurochemical. Therefore, with every Triptherapie registration includes a neurotransmitter test (questionnaire)..
