BIOL 362 is UMGC's three-credit, in-depth discussion of the biology and development of the nervous system.
The University of Maryland Global Campus says the objectives are to apply neurobiological concepts in advanced coursework or professional careers and to become informed about healthcare topics.
The curriculum covers neuronal structure and function, synaptic communication, membrane receptors and cell signaling, brain and spinal cord organization, sensory processing, motor programming, research techniques, ethics, neural development, neuroplasticity, and higher functions such as learning, memory, cognition and speech.
The range is wide, from ion channels to language. Students who connect each level to the one above it, from molecules to cells to circuits to behavior, find the course far more manageable.

Key Concepts Explained
Synaptic Transmission
When an action potential reaches the axon terminal, voltage-gated calcium channels open, calcium enters and triggers release of neurotransmitter. The transmitter crosses the synaptic cleft and binds receptors on the next cell, and its action ends by reuptake, breakdown or diffusion.
Example: Selective serotonin reuptake inhibitors (SSRIs) block the transporter that clears serotonin from the synapse, so serotonin stays longer and signaling increases. Explaining a drug by the synaptic step it affects is a strong answer pattern.
Ionotropic and Metabotropic Receptors
Ionotropic receptors are ion channels that open directly when transmitter binds, giving fast responses. Metabotropic receptors act through G proteins and second messengers, giving slower, longer-lasting effects.
Long-Term Potentiation
Long-term potentiation (LTP) is a lasting strengthening of synapses after repeated activity, studied especially in the hippocampus. It is a leading cellular model for learning and memory.
Example: At many hippocampal synapses, strong activity removes the magnesium block from NMDA receptors, letting calcium in. Calcium triggers signaling that adds more AMPA receptors to the synapse, so the same input later produces a bigger response.
Research Techniques and Ethics
UMGC lists research techniques and ethics among the course topics. Knowing what each method can show helps you evaluate studies you read.
| Technique | What it shows |
|---|---|
| Electrophysiology | Electrical activity of single neurons or networks |
| EEG | Brain activity with excellent timing but limited location detail |
| fMRI | Activity-related blood flow changes with good spatial detail |
| Lesion and stimulation studies | Whether a region is needed for a function |
Ethical questions include research with animals, consent from people with impaired capacity, and the use of brain data. A balanced answer weighs scientific value against risk and dignity.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Mechanism questions | Cellular and synaptic understanding | Sequence the steps and name channels and receptors |
| Disorder or health paper | Applying neurobiology to health | Normal function, what changes, symptoms, treatment |
| Research summary | Interpreting methods and findings | Name the technique and what it can and cannot show |
Neural Development and Plasticity
UMGC includes neural development and neuroplasticity, which show that the nervous system is built and rebuilt by activity. During development, neurons are produced, migrate, extend axons guided by chemical cues and form synapses; many are then removed by programmed cell death.
Plasticity continues for life. Synapses strengthen or weaken with use, and after injury nearby regions can take over some functions.
Example: After a stroke, rehabilitation that repeatedly uses an affected limb can encourage surviving circuits to reorganize. Linking this recovery to synaptic plasticity is a good way to connect cellular mechanisms with health topics.
Where Students Get Stuck
- Membrane potentials. Revise ion gradients and channels until the action potential feels routine.
- Neuroanatomy. Learn regions by function, with a labeled diagram.
- Overstating imaging studies. Activity in a region during a task does not prove the region causes the behavior.
- Linking levels. Show how a synaptic change could alter behavior.
Study Tips for BIOL 362
- Revise BIOL 201 nervous system material before the first week.
- For every drug or disorder you meet, name the synaptic step involved.
- Draw sensory and motor pathways from receptor to cortex and back.
- Read one review article on a topic that interests you, such as memory or Parkinson's disease.
