Chapter 1: Research Methods

  • Many methods have helped neuroscientists discover the structure, connections, and functions of the nervous system
  • Have ability to make detailed observations
  • Histology - refers to study of microscopic structures and tissues
  • Means for observing the structure, organization and connected of individual cells
  • Tissues must be prepared for viewing
  • Must be thin enough to allow light to pass through
  • Step1: “fix” the tissue by freezing it or with formation
  • Liquid containing gas from formaldehyde
  • Hardens / proserves tissue
  • Step2: tissue = sliced by a microtone
  • Works like mini version meat slicers
  • Slices between 10 - 80mm
  • Step3: slices are mounted on slides for viewing
  • Researchers select particular strains to view specific features

Types of stains:

  1. Golgi silver stain: used to make detailed structural analysis of a small number of single cells
  2. Nisel stain: used in identifying clusters of cell bodies, major bulk of the nerve cell
  3. Myelin stain: allows you to follow pathways carrying information. From one part of brain to other
  1. Strains insulating material that covers nerve fibers
  1. Horseradish peroxidase: used if you know where pathway ends but want to find the origin.
  1. Travels backwards towards cell body
  • Immunohistochemistry (IHC): process in which proteins are combined with dyes to highlight particular proteins in the cell
  • Once the tissue is properly prepared, can be viewed using light or electron microscope
  • Light microscope:
  • Electron microscope: uses short, highly concentrated electron beams rather than light to form images
  • Provides clear image

Autopsy

  • Autopsy: an examination of the body following death

“To view for oneself”

  • Must be interpreted carefully and precisely
  • Study structure of the nervous system
  • Still a useful technique today despite the use of modern imaging methods

Imaging

  • Now techniques provide advantage over autopsies
  • Can watch the living brain as it engages in processes
  • Can identify differences in brains of serial killers function vs. typical people

Types of imaging:

  1. Computerized Tomography (CT)
  • 1972 by Godfrey Hounsfield and Allan Cormack
  • Provided 1rst high - resolution look at a living brain
  • Useful for medical imaging

        Drawback

  • Cannot distinguish between a dead and living brain
  • Information regarding activity levels in brain
  1. Positron Emission Tomography (PET): allowed researchers to observe brain activity for the first time
  • Made possible from invention of the gamma camera
  • Used to detect radiation released by radioactive atoms
  • Combines radioactive tracers with a wide variety of molecules
  • Each gamma ray resulting from breakdown of tracer is recorded by detectors and fed to a computer
  • Data reconstructed into images

        Drawback: not much structural detail but offer clear picture of brain activity

  1. Magnetic Resonance Imaging (MAI): standard medical diagnostic tool and valuable research asset
  • Uses powerful magnets to align hydrogen atoms within a magnetic field
  • Radio frequency pulses are directed at part of body imaged
  • Produces spinning of hydrogen atoms
  • As atoms “relax” - radio becomes a mini - radio transmitter
  • Emits pulse detected by scanner

  • Voxel = 3D version of a pixel
  • Darkness / coloration represents level of pulse activity
  • Functional MAI: FMRI = used to assess brain activity
  • Takes advantage of fact that active neurons require more oxygen than less active neurons
