Describe sensory memory and the brain region involved
Lasts seconds, sensory pathways to the primary sensory area
Describe short-term memory and the brain region involved?
Lasts minutes, based on brain region involved
Describe long term memory and where each type is located
Lasts hours to a lifetime, based on information stored -
Hippocampus = episodic memories (events/experiences)
Striatum= procedural memory
Amygdala = emotional associations with stimuli
What must happen for long-term memories to form?
Repeated consolidation & recall
What is implicit memory and what is needed to form an implicit memory?
knowledge or a skill that was acquired without conscious effort and which guides behavior unconsciously
Requires increased exposure or repetition
What are the two forms of implicit memory?
Non-associative: Change in response to a stimulus (habituation)
Associative: A relationship between 2 stimuli or a stimulus and behavior (Pavlov)
What is habituation?
A decrease in the intensity of a reflex/behavior in response to repeated stimulation of the same intensity
What is sensitization
An increase in intensity of a reflex/behavior in response to repeated stimulation of the same intensity
Describe the process of the gill-withdrawal reflex in Aplysia
Tactical stimulus of siphon activates sensory neurons
Sensory neurons synapse and excite motor neurons that innervate the gill.
If motor neuron is excited above threshold, it will fire and excite the muscles that contract the gill.
What happens when the gill withdrawal reflex experiences habituation?
repeated stimulation of the siphon leads to much smaller contraction of the gill-withdrawal muscles through decreased neurotransmitter release onto the gill muscles
What happens during sensitization of the gill-withdrawal reflex?
The motor neuron excitation is increased due to the facilitation from the tail-shock and creates a stronger contraction of the gill-withdrawal muscles through increased NT release onto the gill muscles.
