AMPA Receptor: Its Role in Ketamine's Antidepressant Effect
A glossary entry on the AMPA receptor, explaining what it is, how it functions, and why its activation is essential to ketamine's rapid antidepressant mechanism.
Arketamine (R-Ketamine): The Promising Enantiomer Under Investigation
Learn about arketamine (R-ketamine), the less-studied enantiomer of ketamine showing promise as a next-generation antidepressant with fewer side effects.
Bioavailability: Understanding Ketamine Absorption by Route
A clear explanation of bioavailability and how it varies across ketamine administration routes — IV, IM, intranasal, sublingual, and oral — and why it matters.
Synaptogenesis: How Ketamine Promotes New Synaptic Connections
Synaptogenesis explained: how ketamine triggers new synaptic connections via BDNF and mTOR signaling, and why this drives lasting antidepressant effects.
BDNF (Brain-Derived Neurotrophic Factor): Definition and Role in Ketamine Therapy
Learn what BDNF (Brain-Derived Neurotrophic Factor) is, how it supports brain health, and why it is central to ketamine's rapid antidepressant mechanism.
Glutamate: The Excitatory Neurotransmitter Central to Ketamine's Action
Glutamate, the brain's excitatory neurotransmitter, and why its post-NMDA-blockade surge is central to how ketamine produces rapid antidepressant effects.
Neuroplasticity
What neuroplasticity means, how the brain rewires itself, and why neuroplasticity is central to understanding ketamine's rapid antidepressant effects.
Dissociation
What dissociation means in the context of ketamine therapy — its clinical definition, how it manifests during treatment, and its potential relationship to therapeutic outcomes.
NMDA Receptor
A comprehensive definition and explanation of the NMDA receptor — its role in the brain, its relevance to ketamine therapy, and why it matters for mental health treatment.
