Have you ever been told when you’re stressed to stop worrying and just relax? That it’s all in your head? It would be nice if it were that simple. But it’s not. Physiology research shows that the stress response memory lives in your nervous system. Take for example exposure to a stressful event. One in which you felt helpless, hopeless, and lacked control. In this case your autonomic nervous system (ANS) is engaged. This is the part of the nervous system responsible for controlling unconscious bodily actions like breathing. To be more specific, it was the sympathetic branch (fight or flight) of the ANS that kicked in while you were strained. In addition, the hypothalamic-pituitary-adrenal axis of the midbrain began firing. In which a signal from your hypothalamus sends a hormonal message to your pituitary gland that stimulates to your adrenal glands.

Your brain's ability to collect, connect, and create mosaics from these milliseconds-long impressions is the basis of every memory. By extension, it is the basis of you. This isn't just metaphysical poetics. Every sensory experience triggers changes in the molecules of your neurons, reshaping the way they connect to one another. That means your brain is literally made of memories, and memories constantly remake your brain. This framework for memory dates back decades. And a sprawling new review published today in Neuron adds an even finer point: Memory exists because your brain’s molecules, cells, and synapses can tell time.
