  23. 23. Chemoaffinityhypothesis:Connections arehighly specific.Sperry’s eye rotationexperiment Copyright © 2009 Allyn & Bacon
  24. 24. Topographic Gradient Hypothesis
  25. 25. Topographic Gradient Hypothesis
  26. 26. Synapse Rearrangement
  27. 27. Which factors influence cell death?A. Too few targets for neuronsB. Too many other neuronsC. A lack of neurotrophinsD. Incompatible firing patternsE. All of the above
  28. 28. Neuron Death and Synapse Rearrangement Overproduction: during development many neurons die. – Apoptosis: active, programmed cell death – Necrosis: Passive cell death Neurons die due to failure to compete for neurotrohic factors provided by targets (e.g., NGF, nerve growth factor) – The more targets, the fewer cell deaths – Destroying some cells increases survival rate of remaining cells Copyright © 2009 Allyn & Bacon
  29. 29. Vulnerable Developing BrainMore than 200 genetic mutations associated with mentalretardationDeveloping brain is more vulnerable than the maturebrain to malnutrition, toxic chemicals and infections.Examples: – Hypothyroidism induces mental retardation in infants – Fetal alcohol syndrome. Dendrites tend to be short, with few branches – Rett Syndrome. Anomaly of brain development with mental retardation affecting mainly girls older than 1-2 years. Associated with lack of dendritic development
  30. 30. Learning and Memory
  31. 31. Which structures of H.M.’s brain were removed?A. HippocampusB. Rhinal cortexC. AmydalaD. Medial temporal lobeE. All of the above
  32. 32. As a result of the surgery, H.M. had deficits in what type of memory?A. Semantic memoryB. Skill memoryC. Episodic memoryD. Conditioning memoryE. All of the above
  33. 33. Long-Term Memory Two Parallel SystemsDeclarative (explicit): things Procedural (non-declarative,you know that you can tell implicit): things you know that youothers can show by doingEpisodic: Semantic: the Skill Priming: Conditioning:breakfast this name of the Learning: more likely to salivatingmorning 44th president skiing, riding use a word when I see a a bike you heard nice steak! recently Impaired OK!

  46. 46. Where are Memories Stored? In general, memories are stored in areas that contribute to the acquisition of the memoriesExamples:Inferotemporal cortex: object recognitionHipoocampus: spatial locationAmygdala: learned fearCerebellum: implicit sensorymotor tasksPreforntal cortex: temporal order ofevents, as in cookingStriatum (basal ganglia): habit formation

  49. 49. Hippocampus and Spatial MemoryTheories of Hippocampal Function – Cognitive Map Hypothesis Hippocampus contains a cognitive map of allocentric space that serves as spatial context useful for acquiring and recalling memory of any episode. – Configural Association Theory Hippocampus is critical for learning the significance of combinations of stimuli (i.e., you will be learning about biopsychology in this room, not any other topic) – Spatial Arrangements Hippocampus is important for recognizing the arrangement of objects relative to one another (i.e., the layout of your living room)Milner (1965): “… HM still had not learned the new address (thoughremembering the old one perfectly), nor could he be trusted to findhis way home alone. He did not know where objects in constant usewere kept…”
