Week 1 - Brain Anatomy Tutorial Session 

Visit This will take you to an online tool developed by the cold spring harbor laboratory to allow people to explore neuroanatomy. Note that the original version of this was developed for Adobe Flash player, which is no longer supported in many browsers, but they have developed android and iOS versions which you can install on your mobile device. Follow the links on  to install and run the 3-D Brain. 

3-D Brain. The G2C Brain is an interactive 3-D model of the brain, with 29 structures that can be rotated in three-dimensional space. Each structure has information on brain disorders, brain damage, case studies, and links to modern neuroscience research. Ideal for students, researchers, and educators in psychology and biology.

In this week’s lecture we provided an overview of the basic anatomy of the human brain. As we will spend the semester exploring the brain in greater detail, let’s begin this journey by familiarizing ourselves visually view a few basic brain regions. Follow this link to open an interactive 3D Brain. Explore the structures listed below, then answer the questions to test your knowledge. Once you have finished with that, have a go at the "bonus questions" link below. The questions are not assessed and are open book. They are intended to help you become  more familiar with brain anatomy and anatomical terminology. 

1. (Pons and Pineal)

The brain stem is responsible for a number of basic functions in your body, and connects the rest of your brain to the rest of… you. It is so important, in fact, that a “chicken with its head cut off” can still run around the yard due to it’s brainstem remaining in tact.

a) When you awoke this morning, and when you grew tired towards the end of yesterday, one important (and originally misunderstood) section of your brainstem was responsible for regulating your sense of wakefulness. Do you recall it’s name and what regulatory hormone it excretes?

b) Referring to the “Brainstem” portion on the 3D brain, locate the part of the brain involved with controlling involuntary movements during sleep. Where does it sit in relation to the rest of the brain stem? And in relation to the rest of the brain? 

2. (Basal Ganglia)

The Basal Ganglia play key roles in your "reward system", as well as in planning and coodinating physical movements. We will discuss their role in the neuroscience of addictive behavior later in the this course. Name the sections of the Basal Ganglia. Do you recall what the word “ganglia” refers to? 

3. (Cerebral Cortex)

Let’s take a step back and look at the brain as a whole. There are many parts, but which appears to take up the most space in our skulls? Given what you know about being human, why might this make sense? 

4. (Occipital Cortex and Thalamus)

Seeing is believing, but which part of our brain allows us to believe what we see? As light hits your eyes, the retinas pass information on to two primary brain regions. What are they, and what else do they do?

5. (Pre- and Primary Motor Cortex)

A wise man once said “Get Up. Get Down. Shake your body down to the ground.” Name the two parts of the voluntary motor system and how they function together. Where are they located and how are they connected? 

6. (Limbic System)

The limbic system comprises several brain structures that are collectively responsible for regulation of mood, memory, and arousal. Give examples parts of the limbic system and the functions that each part is most associated with.
