Full Description
This examination centers on the role of ion channels in regulating neuronal excitability and the mechanisms of signal propagation within the nervous system. Specific attention will be paid to channel types, gating mechanisms, and their physiological relevance.
Understanding ion channel function is fundamental for the field of neurobiology, underpinning our knowledge of action potentials, synaptic transmission, and overall neuronal communication. Ion channel dysregulation has implications in numerous neurological disorders.
The assessment will evaluate candidates' abilities to articulate the mechanisms of ion channel function and their implications for neuronal communication and excitability.
Candidates should be prepared to discuss examples of how altered ion channel function contributes to specific neurological conditions.
