3 important questions on Learning and Memory - MOLECULAR MECHANISMS OFLEARNING AND MEMORY - Habituation in Aplysia
Habituation can be categorized into two temporal forms based on the duration of the training and the underlying physiological changes, name these two catergories?
Long term habituation and short term habituation
What is short term habituation and what is the underlying mechanism that cuases it?
Short-term habituation occurs when a stimulus is presented repeatedly over a short period, such as an hour
Mechanism: This form of habituation is caused by a reduction in neurotransmitter release. The sensory neurons release progressively less transmitter weakening the response
Mechanism: This form of habituation is caused by a reduction in neurotransmitter release. The sensory neurons release progressively less transmitter weakening the response
What is long term habituation and what is the underlying mechanism that causes it?
Long-term habituation occurs when the repeated training takes place over the course of several days
Mechanism: This more permanent form of habituation involves structural changes in the nervous system. Specifically, it is due to the retraction of some synaptic terminals from the sensory neurons that connect to the motoneurons, resulting in fewer functional connections
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
