Brain Areas in Life Tiana Chan 301.201.275 COGS 100: Exploring the Mind; Picard Due date: Thurs, Nov.8 Identify how EACH of the following brain structures might be involved in TWO of the following five, everyday functions: (1) waking up and getting out of bed, (2) driving a car, (3) watching TV, (4) listening to music that makes you sad (evokes memories of a past relationship), and (5) learning to ride a bike. Use all five functions about an equal number of times. Be specific. Sensory neurons Ex 4 – After the electrical action potential has occurred, chemicals go to the brain and are submitted to sensory neurons that makeup our brain and nervous system. Activity in the Hypothalamus result in the detection of these chemicals that results to emotions. So when you’re listening to music, sensory neurons render the activation of certain chemicals responsible for emotion. Ex 5 – Learning to ride a bike would generate new connections in your brain. The external world of you learning to ride a bike our render new and strengthen some connections in the brain. They are responsible for thoughts and feelings and are responsible to communicate info from external to internal. Motor neurons Ex 5 & 2– Neurons located in vertebrates in the spinal cord, which synapses with muscle fibres to control muscles. These would be used during physical activity such as using your leg muscles when riding a bike and using your eye muscles when having a broad visual field when driving. Sympathetic nervous system Ex 5 – This acts as the automatic nervous system. So lets say you’re learning to ride a bike and you’re falling off. Your hands will, by reflex, come out in front of you and you’ll fall on your hands. There’s no brain activity there. It’s all by reflex thus the reason why it acts as the automatic nervous system. Ex 1 – Let’s say there was a fire and you’re sleeping. Getting out of bed because the air is condense and smoky would trigger the sympathetic nervous system since your reflex would be to jump out of bed without having to have elaborated thoughts about your action. Parasympathetic nervous system Ex 5 – It regulates automatic reflexes & autonomic activities. Once more, when riding a bike you would use this system when you’re balancing on your bike. To keep balance you usually use automatic reflexes. Ex 1 – When you’re getting out of bed and you sit up straight, you use your balance, which is parallel to the response of automatic reflexes. Corpus callosum Ex 2 – Combines images from right and left eye & create depth perception. When you’re driving a car the corpus callosum is essential to avoid getting in car crashes and to be able to have a wide visual field. Ex 3 – When watching TV perception is important to be able to detect depth in the picture that is being screened. Occipital lobe Ex 3 & 2 – Helps see and identify. It controls visual processing. Therefore, when you’re watching TV the occipital lobe would be in use since you’re identifying colours in the picture. Same as when you’re driving, identifying colours of lights and shadows of cars can help you drive safer. Temporal lobe Ex 4 – Responsible for speech, memory, reading, emotional responses and auditory responses. Therefore, when you’re listening to music that evokes past memories which would then make you sad, you’re using your temporal lobe since it is responsible for recognition of memory and emotional responses. Ex 2 – When you’re driving a car you’re constantly reading signs and identifying streets and such. Memory is also important since you must remember all the driving rules and regulations to be a safe driver. Parietal lobe Ex 5 – Responsible for understanding of position and/or balance of the body and your surroundings. The right lobe is essential for personality and the left is responsible for COG tasks. Therefore, when you’re learning to ride a bike positioning, balance and understanding of surroundings is highly important to have a broad visual field. Ex 2 – When driving a car, it is also important to be aware of your positioning and surrounding environment. Frontal lobe Ex 1 – Important for motor functions, higher order functions, planning, reasoning, judgement, impulse control, memory etc…It is important when you’re waking up and getting out of bed to plan your day and schedule your tasks for that day. Ex 3 – If you were to watch a documentary, watching TV would activate
