What is declarative memory?
|
explicit, memories about facts events. Learning and memory. Conscious (active) involvement
|
|
|
Does declarative memory act fast or slow?
|
it occurs fast
|
|
|
Can declarative memory occur from one exposure
|
It may occur in one trial (exposure) if so it’s something that is emotional
|
|
|
Are the stimuli in declarative memory simultaneous or sequential?
|
Simultaneous stimuli.
|
|
|
Which parts of the brain are required for declarative memories?
|
Hippocampus and the prefrontal cortex
|
|
|
What is non-declarative or implicit memory?
|
What you learn here are rules regarding behavior. All of the Simple forms of memory are non-declarative. Cognitive skills; No conscious participation.
|
|
|
Does non-declarative memory form fast or slow?
|
Participation is slow in that there is many trials and much practice involved
|
|
|
Are the stimuli in non-declarative memory simultaneous or sequential?
|
Stimuli are sequential → prediction
|
|
|
Are the hippocampus and prefrontal cortex required for non-declarative memory?
|
The hippocampus and prefrontal cortex are not needed
|
|
|
What are the two cellular mechanisms for forming “associations” during learning?
|
1. Premodulatory associative mechanism; 2.Prepost associative mechanism
|
|
|
Is the premodulatory associative mechanism from declarative or non declarative memory?
|
(non-declarative)
|
|
|
Where is the conditioned stimulus located in the premodulatory associative mechanism?
|
Conditioned stimulus is on presynaptice neuron
|
|
|
Where is the unconditioned stimulus located in the premodulatory associative mechanism?
|
the unconditioned stimulus is on the modulatory neuron.
|
|
|
When are the conditioned and unconditioned stimulus active in the premodulatory associative mechanism?
|
These are active at the same time
|
|
|
Where does the change occur in the premodulatory associative mechanism?
|
Changes occur at the synapse
|
|
|
Where does the response occur in the premodulatory associative mechanism?
|
The response is on the postsynaptic neurons.
|
|
|
Where is most classical conditioning located in mammals?
|
it is at the cerebellum
|
|
|
How is behavioral timing related to physiological timing?
|
Behavioral timing= physiological timing
|
|
|
Where is Long-term potentiation (LTP) & NMDA receptors involved in brain locations?
|
in many brain locations where non declarative memories are formed; all locations where declarative memories are formed.
|
|
|
Is the prepost associative mechanism declarative or non-declarative?
|
Declarative
|
|
|
In the prepost associative mechanism how are the neurons connected?
|
The presynaptic neuron synapses with the postsynaptic neuron; the modulatory neuron synapsing on the terminal button of the presynaptic neuron.
|
|
|
How important is the modulatory neuron in prepost associative mechanism?
|
The modulatory neuron isn’t really important here; it doesn’t have to be active. Only the first two have to be active at the same time
|
|
|
What is Hebbs theory?
|
he theorized that in your brain there was a reverbatory circuit that was, so that they could be stimulating each other and keep the info going around until a permanent changed occurred that we would call memory
|
|
|
Where is the reverbatory circuit actually located?
|
The reverbatory circuit is actually the hippocampal formation
|
|
|
What are permanent changes in the circuit called?
|
The permanent changes in a circuit he called cell assemblies we call them neural networks.
|
|
|
What accounts for the differences in learning rates?
|
People learn at different rates because they form cell assemblies faster or slower.
|
|
|
What does the Right hippocampal formation do?
|
Consolidation & retrieval of new (about 1 week) declarative memories (episodic, semantic, spatial, relational)
|
|
|
Because Taxi drivers have larger _______ they are better at spatial tasks
|
Right posterior hippocampus
|
