  1. Functional Neuroanatomy adapted from:Brad Dickerson, M.D.bradd@nmr.mgh.harvard.edu

  2. bradd@nmr.mgh.harvard.edu Functional neuroanatomy • Overview of brain anatomy & systems • Localization/networks • Scale in the nervous system • Sensorimotor systems • How our brains interact with the external world (loops) • States ‘of mind’ (and body) • Specific functional systems • Memory & emotion • How our brains use previous experience to modify behavior • Vision & attention; language

  3. Brain anatomy

  4. Brain anatomy

  5. Brain anatomy

  6. Brain anatomy

  7. Brain anatomy

  8. Brain anatomy

  9. Approaches to the study of brain function • Animals & humans: anatomy, physiology, & behavior • Tract tracing • Single unit recordings • Behavioral studies; pharmacology • Patients with focal brain lesions • Behavioral studies & post-mortem anatomy • Structural imaging: In vivo structure/function correlations • Neuroimaging/brain mapping • Functional neuroimaging

  10. Localization of function in the nervous system Phrenology (Gall, early 1800s) 1.The brain is the organ of the mind. 2. The mind is composed of multiple distinct, innate faculties. 3. Because they are distinct, each faculty must have a separate seat or "organ" in the brain.

  11. Localization of function in the nervous system: Paul Broca & language 1860s

  12. What are we doing with our brains at this moment?(The student’s brain) • Feeling your chair • Squirming (moving) • Watching • Listening • Remembering • Paying attention • Sleeping • Feeling anxious • Feeling hungry • What happens when you ask a question?

  13. Motor function

  14. Motor system

  15. Motor system:Topography

  16. Motor system

  17. Somatosensory function

  18. Review of Somatosensory Cortex

  19. Conservation

  20. Vision

  21. Visual system

  22. The Brain is Composed of Discrete Cells: Neurons and Glia

  23. The Brain is Composed of Discrete Cells: Neurons and Glia

  24. Neurons communicate with each other primarily through synapses

  25. Glia support and maintain neurons • Protect by surrounding and buffering • Speed transmission by forming myelin sheaths

  26. What are we doing with our brains at this moment?(The student’s brain) • Feeling your chair • Squirming (moving) • Watching • Listening • Remembering • Paying attention • Sleeping • Feeling anxious • Feeling hungry • What happens when you ask a question?
