How can dose ketamine 'reorganize':
A simple dose of ketamine could change communication between different regions of the brain. In addition, This discovery opens up new perspectives on the treatment of mental disorders.
Research. Nevertheless, presented at the Psychedelic Science 2025 conference, is looking at the impact of ketamine on neuroplasticity in humans. Similarly, Neuroplasticity designates the ability of brain to adapt in formant new connections. Therefore, Although the results have not yet been evaluated by peers. Furthermore, they offer precious lighting on the mechanism of action of this substance.
Clinical trials have already shown the effectiveness of ketamine against depression in a few hours. In animals, it stimulates the growth of new dendritic thorns, essential for synapses. However, its functioning in humans remains poorly understood. To how can dose ketamine ‘reorganize’ see more clearly, the researchers scanned the brain of 11 men before and after the administration of ketamine.
The study used magnetic resonance imaging functional (Irmf) to observe changes inactivity cerebral. Normally. high -level brain networks, such as “network Default mode “(Default Mode Network or DMN in English), communicate less with low -level sensory networks. After taking ketamine, this hierarchy seems communication increased between these networks.
The DMN, often associated with reverie and planning, is linked to depression when it is too active. PET scanners have also revealed changes in the posterior cingular cortex, a key region of the DMN. These observations suggest that ketamine reorganizes brain communication, thus offering a potential explanation for its effect antidepressant.
Despite these promising results. the study has limits, such as a small number of participants and the absence of a placebo group. However, it represents an important step in understanding how can dose ketamine ‘reorganize’ the action of ketamine on the human brain.
What is neuroplasticity? – How can dose ketamine 'reorganize'
Neuroplasticity is the remarkable capacity of the brain to reshape through life. It allows the training of new neural connections in response to learning or experience.
This phenomenon is crucial for recovery after a brain injury. He also explains how certain therapies can permanently modify the brain circuits involved in mental disorders.
Ketamine, by promoting neuroplasticity, could therefore ‘reset “certain dysfunctional circuits. This property makes it a promising candidate for the treatment of resistant depression.
However, the precise mechanisms by which ketamine acts on neuroplasticity remain to be elucidated. Additional research is necessary to fully understand its therapeutic potential.
How does the default mode work (DMN)?
Default mode is an active brain network when we are not focused on the outside world. It is involved in reverie, reflection on oneself and memory.
Excessive DMN activity has been associated with disorders such as depression. how can dose ketamine ‘reorganize’ The people concerned tend to ruminate, that is to say to get lost in repetitive negative thoughts.
Ketamine seems to reduce this hyperactivity, allowing better regulation of thoughts. This could explain its rapid effect on depressive symptoms.
The DMN also plays a role in the integration of information between different regions of the brain. His dysfunction could therefore affect many aspects of cognition and mood.
