ACADEMIC INTEGRITY

Plagiarism:

  • An Excerpt From Your Textbook:

Behavior results when a signal travels from a sensory receptor, through some number of synapses in the central nervous system, and out through a motor neuron, activating skeletal muscles. Even in the simplest neuronal circuits, information coming both from other neurons in the same part of the nervous system and from neurons with somata in distant locations impinges on the circuit and can modify the behavioral output.

Plagiarism:

  • In Text Citations:
    • Behavior in animals is the result of a complex web of interconnected neurons communicating with one another (Randall et al. 2002).
    • A behavioral response to a stimulus often involves multiple neurons, each of which may have numerous inputs (Randall et al. 2002).
