Content Outline
PreviewUnit 3125: Neuroscience and Nervous System Function
1. Neurons and Neurotransmission
1.1 Structure of Neurons
- Components: dendrites, soma, axon, myelin sheath, synaptic terminals
- Types of neurons: sensory, motor, interneurons
1.2 Function of Neurons
- Resting potential and membrane properties
- Generation of action potentials: depolarization, repolarization, refractory period
1.3 Neurotransmission Process
- Synaptic transmission steps: neurotransmitter release, receptor binding, signal propagation
- Types of neurotransmitters: excitatory vs inhibitory
- Role of neurotransmitters in neural communication
2. Central Nervous System (CNS) and Peripheral Nervous System (PNS)
2.1 Overview of the Nervous System
- Division into CNS and PNS
2.2 Central Nervous System
- Brain: overview of structure and function
- Spinal cord: role in reflexes and signal transmission
2.3 Peripheral Nervous System
- Somatic nervous system: sensory and motor pathways
- Autonomic nervous system: sympathetic and parasympathetic divisions
3. Brain Anatomy and Function
3.1 Major Brain Regions
- Cerebrum: lobes and cortical functions
- Cerebellum: coordination and balance
- Brainstem: vital functions and pathways
- Limbic system: emotion, memory, and motivation
3.2 Functional Roles
- Motor control and sensory processing
- Cognitive functions such as language, decision-making, and problem solving
4. Neuroplasticity and Learning
4.1 Definition and Mechanisms
