Modular Credits: 4
  Tags: Neurology,Neuroscience,Signaling

Learning Outcomes

TopSignaling within and between neurons provide the basis for information processing, storage and retrieval in the brain. This is a foundational module and the knowledge learned will enable students to appreciate the fundamental processes underlying brain function. Signaling within and between neurons provide the basis for information processing, storage and retrieval in the brain. This module will consider several fundamental aspects of neuronal signaling, including: (1) the ionic basis of membrane excitability; (2) basic mechanisms of synaptic transmission; and (3) mechanisms of synaptic plasticity and their implications for learning and memory.

Syllabus

Top Detailed topics description:  

1. Principles of Neuronal Electrical Signalling
  • Ionic Basis of Membrane Excitability
- The ionic basis of resting and action potential will be discussed.
  • Ion channels
- The molecular biology of ion channels and receptors and their roles in generation and maintenance of electrical activities will be discussed in relation to synaptic transmission. Examples of ion channelopathies will be used to reinforce that subtle changes in ion channel function can produce severe phenotypes in rodents or in human.

2. Synaptic transmission
  • Presynaptic mechanisms
- The mechanisms underlying neurotransmitter release will be considered. Topics to be discussed include presynaptic calcium signaling, molecular mechanisms of synaptic vesicle trafficking, and quantal transmitter release.
  • Short-term synaptic plasticity
- We will begin our analysis of synaptic plasticity by considering the mechanisms underlying short-term synaptic plasticity, namely changes in synaptic function that persist for less than 30 minutes.
-Mechanisms: facilitation, post-tetanic potentiation (PTP), presynaptic depression, and postsynaptic desensitization.
  • Postsynaptic mechanisms
- The mechanisms involved in postsynaptic signalling will be considered, including an analysis of the properties of neurotransmitter receptors and biophysical aspects of postsynaptic electrical signals.

3. Synaptic plasticity
  • Long-term synaptic plasticity
- The module will conclude by considering the signalling mechanisms responsible for long-term synaptic plasticity, such as long-term potentiation (LTP) and long-term depression (LTD), and the possible roles of these forms of plasticity in memory formation and storage.
- LTP, LTD: the features, and the associated signaling mechanisms, synaptic tagging
 
  • Structural plasticity of synapses
 
  • Memory formation and storage
