 Hi, my name is Sebastian Matau and welcome to this video on neurons and brain anatomy in video course biological psychology This this first video video 2.1 is the introduction to this lecture to the full lecture on neurons and brain anatomy So let's start with a little bit of reading So if you want to read some more of the stuff that we're going to talk about in this lecture I recommend that you download the free textbooks that have been provided by open stacks very good free textbooks And especially from the psychology textbook chapters sections 3.2 3.3 and 3.4 and From the anatomy and physiology textbook also from open stacks Chapter 12 about the nervous system and nervous tissue Now the anatomy and physiology textbook is fairly detailed So if you really want to get into this subject matter I would recommend reading chapter 12 from that textbook if you prefer to have a more Quicker less in-depth the introduction into neurons and brain anatomy I think that the psychology textbook is a good start and of course you can read both I always like to recommend for the interested viewer More accessible book and popular science book and for this lecture I would like to recommend how intelligence happens which is written by has been written by John Duncan now John Duncan is really one of the world's best in my opinion a neuroscientist and We will also meet some of his contributions to research at later points in this this course For example when during the course on attention the lecture on attention We're going to talk about the biased competition theory of attention which was proposed among others by John Duncan So he's really a very big name in the field and in this book, which I like a lot He talks about how the brain gives rise to intelligent behavior So it's really a book that like this course operates on the the frontier between psychology and and and biology right the link between brain and behavior Now what are we going to talk about in this section this this lecture about neurons and brain anatomy in the the next video video 2.2 We're going to talk about what a neuron is which you probably know a neuron is a brain cell and about the membrane potential Which is an important concept when talking about neurons Then in video 2.3 We're going to talk about synapses which are connections between neurons and Action potentials and an action potential is basically a spike of activity of a single neuron It's what happens when a neuron becomes active Then after we've looked at the smallest part of the brain right neurons You can think of neurons as the smallest building blocks of the brain. I think of course neurons are themselves build up out of out of molecules and atoms, etc But I think from a from a biological psychology perspective. You can say that neurons are the smallest elements that really matter So that's where we will start and then in In video 2.4 We will take a more bird's-eye view and look at the brain from a more large-scale perspective and learn to navigate the brain So what kind of terms we use to describe what the front of the brain is and the back of the brain is etc And in 2.5 We're going to look at the major divisions of the nervous system, right? So the labels that we use to describe the different parts of the nervous system This this section that we're going to talk about now these videos Form the basis for the rest of the course biological psychology And it is I think immediately the most information dense parts of part of the course because by its very nature Really talking about neurons and action potentials is quite detailed. It's quite complicated stuff But it's necessary if we want to be able to understand the more cognitive processes like memory Perception and attention that we're going to talk about later Now and don't don't expect to remember everything in one go Especially if you have no background in chemistry or biology, that's totally okay The goal is to get a general idea of how the brain works So to try to understand the general principles of neural communication and the general architecture of the brain and Then if you want to get a more in-depth knowledge of how everything works You can just take your time to review the slides right or review this video and to read the relevant chapters in the open stacks Textbooks until you kind of gradually incorporate all the information That is in here With that let's move on to the next video. We're in which we're going to talk about neurons and the membrane potential
