Chapter 10: The Central Visual System
Retina doesnt simply pass along information; it extracts information about different facets of visual image.
What we perceive depends on what information extracted and how information analyzed and interp
Chapter 4: The Action Potential
Cytosol in neuron negatively charged with respect to the extracellular fluid.
Frequeny and patterm of action potentials constitute code used by neurons to transfer information from one
location to another
Chapter 7: Structure of the Nervous System
General organization of mammalian rain and terms used to describe it
Look at how three-dimensional structure of brain arises during embryological and fetal development
Gross Organization of The Mam
Chapter 5: Synaptic Transmission
Transfer of information rom one neuron to another occurs at specialized sites of contact
Process of information transfer at synapse is called synaptic transmission
Electrical synapses: electrical current fl
Chapter 2: Neuron and Glia
Different types of cells in the nervous system
o Neurons: sense changes in environment, communicate changes to other neurons, command bodys
responses to sensations
o Glia/glial cells: contribute to brain function m
Chapter 3: Neuronal Membrane at Rest
Nervous system has to collect, distribute, integrate information.
Solves problem of conducting information over a distance by using electrical signals that sweep along axon.
Axonal membrane has properti
Chapter 1: Neuroscience: Past, Present, and Future
