Molecular neuroscience studies how molecules inside and around nerve cells make thoughts, feelings, movement, learning, and memory possible. It sits at the intersection of biology, chemistry, and neuroscience, asking questions such as: How do neurons communicate? How do genes control brain cells? Why do some molecules change behavior while others do not?

Neurons are cells, and cells are built from molecules such as proteins, lipids, sugars, and nucleic acids. These molecules determine how a neuron is shaped, how it sends signals, how it responds to stress, and how it changes during learning. In other words, behavior emerges from chemistry organized in living cells.
