Transcript
Neuroscience and Behavior Presented by Rachel Barnes, Ph.D. Neurons Cells made of 3 main parts: Soma/Cell body Dendrites - “branches” that receive information Axons - transmits information How do neurons communicate? http://www.youtube.com/watch?v=SCas ruJT-DU And after the neuron fires… All kinds of neurotransmitters… Ach - movement, attention, learning, memory, sleep + dreams DA - movement, motivation, pleasure, arousal Glu - learning and memory GABA - normal brain functioning Endorphins - physical pain, emotion In real life…. What do you make of this complex biochemical process? Can you think of examples of neurological disorders that you, friends, or family have encountered (ex. Parkinsons, Alzheimers, etc.)? How might drug use affect neurons and their ability to communicate with each other? Brain Structure Frontal lobe—conscious thought; damage can result in mood changes Parietal lobe —plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved with visuospatial processing Occipital lobe —sense of sight; lesions can produce hallucinations Temporal lobe —senses of smell and sound, as well as processing of complex stimuli like faces and scenes. The hemispheres of the brain So what might go wrong? Think about the function of each lobe. What might go wrong if there was an accident or stroke in a certain part of the brain? Please give an example. In the past, one way to treat epilepsy was to disconnect the two halves of the brain? What were the effects on those patients thought and perceptions? Much of the chapter covered neuroscience how does the role of the psychologist and behavior come into play? Reminders Please be sure to answer both discussion questions 150 words minimum, 2 responses for each question (50 words minimum) If you haven’t yet handed in your Unit 2 project, always better later then never. This chapter is full of information that may be brand new to many of you - please check out the links in the following slide for further, simplified information Additional resources http://www.braininjury.com/symptoms. html http://www.youtube.com/watch?v=CiZL nbKVIhM
