17 Questions
Which theory proposes that our experiences are represented by the pattern of firing across a large number of neurons?
Population coding
What is structural connectivity in the context of brain function?
The road map of fibers connecting different areas of the brain
What is the main focus of the distributed representation approach to information processing in the brain?
Patterns distributed across the cortex, involving multiple brain areas
Which concept is associated with the idea that specific brain areas are specialized to respond to specific types of stimuli or functions?
Modularity
What does research suggest is just as important for perception as the activity in each individual brain area alone?
Connections between brain areas
What is the role of excitatory transmitters in the postsynaptic neuron?
Cause depolarization and increase the likelihood of an action potential
What occurs when inhibitory transmitters are released in the postsynaptic neuron?
Cause hyperpolarization and decrease the likelihood of an action potential
What is the function of neurotransmitters in synaptic transmission?
Received by the postsynaptic neuron on receptor sites
What is sparse coding in the context of neuronal activity?
Occurs when a particular stimulus is represented by a pattern of firing of only a small group of neurons
What happens when sodium ions cross the membranes of neurons?
Cause depolarization and increase the likelihood of an action potential
What did Hartline discover about the receptive fields of ganglion cells?
They responded only when a small area of the retina was illuminated
In what way do ganglion cell receptive fields differ from single photoreceptors?
Receptive fields cover a much greater area than a single photoreceptor
What did Stephen Kuffler observe about ganglion cell receptive fields in cats that Hartline did not observe in frogs?
Center-surround receptive fields arranged like concentric circles
How are ganglion cell receptive fields arranged, according to Stephen Kuffler's observations?
In a center-surround organization
What occurs when stimulating a particular point on the retina in relation to ganglion cells' receptive fields?
It generally activates a number of fibers in the optic nerve
How does the monitoring of the retina by ganglion cells compare to spectators at an event?
Many ganglion cells monitor the retina, just as there are many spectators at an event
What property did ganglion cell receptive fields have, according to Stephen Kuffler's research?
'Center-surround' receptive fields
Test your knowledge of the chemical basis of action potentials and neuronal communication, including topics such as ion channels, neurotransmitters, and synaptic transmission.
