Questions with Complete Solutions
Dynamic system theory - Answer-any system, including the human nervous system, can
be studied at various levels of analysis
Nonlinear dynamic - Answer-the whole can be understood by the sum of the parts
Microscopic - Answer-molecules & cells in the nervous system (otoliths)
Mesoscopic - Answer-groups of cells linked together in various systems (vestibular
system)
Macroscopic - Answer-the whole human interacting in their environment (child swinging)
Distributed control - Answer-at any one time, the nervous system coordinates many
different activities (taking notes in the classroom)
Adaptation - Answer-the human nervous system is able to change which can lead to
changes in behavior; it can be shaped by the environment
Neuro-occupation - Answer-reciprocal relationship between the nervous system and
occupation
Localization of function - Answer-particular structures in the nervous system can loosely
be tired to particular functions
Topographical organization - Answer-the brain can loosely be compared to a map
(homunculus)
Brodmann's areas - Answer-classification system which uses numbers to label
individual areas of cortex that are cellularly similar
Hemispheric specialization - Answer-each hemisphere of the brain is connected to
some specific function (lang on left for most people)
Phylogenetic layers - Answer-most newer parts of our brain are located at the top of our
head and the more primitive parts located deeper and lower
