Ketamine works differently from traditional antidepressants. Instead of targeting serotonin, it acts on the brain’s glutamate system, which is involved in learning, memory, and emotional regulation. Specifically, ketamine blocks a receptor called NMDA, which leads to a cascade of effects that encourage neuroplasticity—your brain’s ability to rewire itself.

In people struggling with depression, trauma, or chronic anxiety, the brain often gets stuck in rigid loops of thought—like hopelessness, fear, or self-criticism. Ketamine helps loosen those loops and create space for new insights, emotions, and ways of seeing the world.

It also quiets a part of the brain called the default mode network, which is often responsible for ruminating, replaying the past, or worrying about the future. This shift can feel like emotional spaciousness or a break from the usual inner chatter.

While the effects are temporary, they open a critical window for healing. With the right support—like intention-setting, reflection, and integration—these brain changes can support deep, lasting transformation.
