Functional neuroanatomy
bradd_at_nmr.mgh.harvard.edu
  • 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

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

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.

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

The Brain is Composed of Discrete Cells Neurons

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
