Ketamine and Neural Circuits
The habenula plays a crucial role in generating feelings of disappointment by inhibiting the brain's reward circuitry, which is rich in dopamine. Ketamine can reduce this inhibition, making the reward pathways more accessible. However, true relief from depression requires active engagement in positive behaviors, as neural circuit changes must be reinforced through daily activities for lasting mental health benefits.In this clip
