Neurobiology delves into the intricate workings of the nervous system, exploring the molecular, cellular, and systems-level processes that govern brain function. Research in this field examines how neurons communicate, how synaptic plasticity shapes learning and memory, and the role of neurotransmitters and receptors in regulating behavior. Advances in neurobiology have led to greater understanding of the underlying mechanisms behind neurological diseases such as Alzheimer's, Parkinson’s, and autism spectrum disorders. Additionally, neurobiological studies are focused on brain development, neurogenesis, and the brain’s ability to adapt to injury. With cutting-edge techniques such as optogenetics and single-cell RNA sequencing, neurobiologists are making significant strides in uncovering how the brain processes information and how dysfunction in these processes leads to disease.
