 Good day everybody. Welcome to our next episode of the section of the human brain. Today I'll talk about two things. I'll talk about the components of what is known as the basal forebrain, and then I'm going to talk about the so-called meso-limic and mesocortical structures of the mesocortical tracts with two clinical correlations. Before that, my name is Dr. Sanjay Sanyal. I'm the professor and course director of neuroscience and the camera person is Mr. Mark Lesser.
