PSYC 365 Chapter 2: Cognitive neuroscience
questions with correct answers
michael gazzaniga and george armitage miller 1976 Correct Answer-
coined the term cognitive neuroscience
rejecting the brain as a computer metaphor Correct Answer-- parallel
processing instead of sequential processing
- high-dimensional, distributed representations instead of symbolic
representations
- constant interaction between environment and brain modulated via
sensory input instead of passive, unidirectional input
levels of analysis concept Correct Answer-- we do not examine topics of
interest from a single perspective, rather we look at them from multiple
angles and different points of view
- each view point can add small amounts of information that, when
considered togehther, lead to greater understanding
early concepts of neurons Correct Answer-the early concept of a neuron
was that they created a nerve net
- fast, nonstop communication of signals throughout the network
- the brain looked like this early on due to lack of clear deatiles in the
tecnology of the time
building block of the nervous system Correct Answer-neurons, cells
specialized to create and retrieve signals in the nervous system
, parts of a neuron Correct Answer-cell body
dendrites- receive signals from other neurons
axons/nerve fiber- transmit signals to other neurons
what facilitates neuronal communication? Correct Answer-- a small gap
between the end of a neuron's axon and the dendrites or cell body of
another neuron, called a synapse
- neurons form connections only to specific neurons, this forms neural
circuits
explain receptors Correct Answer-neurons in sensory organs called
receptors
- have receptors instead of dendrites that pick up stimuli from the
environment
Edgar Adrian Correct Answer-recorded electrical signals from single
sensory neurons
- recording electrode inside axon
- recording electrode outside axon
- measure the difference between reference of recording electrodes
action potential Correct Answer-the change in electrical potential
associated with the passage of an impulse along the membrane of a
muscle cell or nerve cell.
