A snapshot of the summary - Neuroscience. Author: Dale Purves ISBN: 9780878936977

  • 1 Studying the Nervous System

  • 1.3 "Model" Organisms in Neuroscience

  • Why do we use different animals for studying the nervous system? Which animals do we examine?
    All used animals have their own benefits and asssumptions.
    - Worm
    - Fruitfly
    - Zebra fish
    - Mice
  • 1.4 The Cellular Components of the Nervous System

  • What is the 'neuron doctrine'? (Sherrington, Golgi, Cajal)
    Neurons form a continuous nerve cell network
  • Name some methods that were used to study the nervous system.
    First they used the light microscope and stained neurons with silver salt to study the nervous system. Later in the 1950's when the electric microscope appeared the research became clearer
  • 1.6 Neuroglial Cells

  • Name the function of glial cells.
    - Recovery and development of neuronal networks
    - Maintaining the ionic milieu of neurons
  • Where are Schwann cell located? In the periphery of CNS?
    Schwann cells are nerve cells which are myelinated (enveloped by glia cell) and are located in the periphery
  • What can be concluded out of the fact that the axons of interneurons are short?
    Interneurons only participate in the local aspects of the circuit
  • 1.7 Cellular Diversity in the Nervous System

  • What is the Nissl method?
    A method of staining the nervous system (blue) such stains demonstrate that the size, density and distriution of the total population of nerve cells is not uniform from region to region.
  • What can be observed with antibody stains?
    Antibody stains used on tissue can recognize specific proteins such as synapses and dendrites
  • 2 Electrical Signals of Nerve Cells

  • 2.2 Electrical Potentials across Nerve Cell Membranes

  • What is the difference between receptor potential, synaps potential and action potential, with respect to encoding intensity?
    The intensity of a receptor potential is encoded in proportion to the magnitude of the stimulus. An synaps potential is encoded in proportion to the number of synapses stimulated. The intensity of a stimulus of an action potential is encoded in the frequency of action potentials occuring.
  • 2.3 How Ionic Movements Produce Electrical Signals

  • What does an active transporter do in the cell membrane?
    It moves ions in and out the cell against their concentration gradient. This creates [ion]-gradients. Active transporters need ATP to move ions
