AIMS AND CONTENT

LEARNING OUTCOMES

  • Neuronal models
  • Synapses and synaptic plasticity models
  • Network models

AIMS AND LEARNING OUTCOMES

Goal of the teaching is to provide the theoretical contents for modeling neuronal structures at different scale, from single neuron up to large-scale complex networks. For this reason, the course will be focused on how to model and simulate the electrophysiological activity of neuronal structures. At the end of the course, the bioengineering student will have strong skills to deal with neuroengineering issues.

Teaching methods

Combination of traditional lectures, classroom discussion, and lab activities.

EXAMS

Exam description

Oral exam about all the topics of the teaching.
Exams will be during the months of December, January, February, June, July, and September. No others exams will be provided during the year. After the exam, the student has 1 week to decide if the mark is fine or not. After this 1 week, the exam will be signed with the assigned mark.
If a student accomplishes a positive grade (greater or equal to 18/30), but he is not satisfied, he can give only once the exam, and in this occasion, the exam will be signed.

Assessment methods

Oral exam about the basic and advanced techniques for modeling neuronal structures from single neuron up to large-scale neuronal networks.
