In this Intro to Neuroscience course, students will explore the fundamental principles of how the nervous system functions, from the cellular level to complex brain processes. The course begins with the foundations of neurobiology, including an overview of cell types such as prokaryotic and eukaryotic cells, along with the roles of DNA, RNA, and protein synthesis in neural function. Students will then be introduced to the electrical principles of nerve signaling, learning how charge, voltage, and current operate within neurons. Building on this, the course examines the organization of the nervous system, covering the central and peripheral divisions, the structure and function of neurons, and the mechanisms of neuronal signaling and synaptic transmission. Special attention is given to the influence of neurotransmitters and the effects of psychoactive drugs on the brain. The final portion of the course provides an in-depth study of the brain’s structure and function, exploring its major divisions and lobes, hemispheric lateralization, and plasticity. Students will also gain a thorough understanding of sensory processing, including taste, smell, vision, audition, somatosensation, proprioception, and balance.
