Neuroscience Course for Basic Medical Sciences

by Sanjoy Sanyal

Description:

Neuroscience is a comprehensive lecture and laboratory course that provides an integrated multidisciplinary study of the structure and functional relationships of the central and peripheral nervous systems. Essential to a proper understanding of Neurosciences is the ability to classify, correlate, associate and link the various entities and modules, much the same way as normal human cognition works in real life. This subject assumes basic knowledge of anatomy of Head and Cranial nerves. The syllabus is divided into easily understandable modules based on Snell’s chapter, supplemented by Board Review Series. Neurobiology and neurophysiology, brain metabolism, and the effects of damage and disease on cells of the central nervous system are covered in detail in the initial part of the course. Students are also introduced to techniques of neuro-imaging and taught introductory clinical assessment during this time. Thereafter the entire central nervous system, from spinal cord upwards to the cerebral cortex, is covered in minute detail. Each component of CNS is subdivided into two parts; the normal concepts and the pertinent clinical correlations. Knowledge is imparted by comprehensive techniques that utilize visual, verbal, auditory and kinesthetic learning styles of individuals. Learning is enhanced through laboratory gross brain dissection, imaging techniques and discussion of clinical correlations. Research skills are honed by subjecting students to a small project work, which they have to present towards the end of the course.

Course:

Lecture-series 1: Introduction and Organization of the nervous system
