How can a brief moment of neural activity leave a lasting trace in the brain? Long-term potentiation offers one possible answer, showing how repeated or coordinated activity can strengthen synapses and support learning. Yet memory depends on far more than a single strengthened connection.

Long-term potentiation is the process through which repeated neural activity strengthens a synapse, helping experience leave lasting changes in the brain.

Interoception is the brain’s ability to sense and interpret signals coming from inside the body, from heartbeat to breathing and internal tension. This hidden dialogue between brain and body helps shape emotion, attention, and wellbeing more than we often realise.
