which of the following is believed to be the neural basis for learning and memory course hero

Full Answer

How are new and frequently used neural connections strengthened?

new and frequently used neural connections are strengthened through experience with the environment

Where do neurons move?

neurons move to their final location in the central nervous system and the location determines what their function will be.

What neuron is stimulated by glutamate?

The repeated glutamate release stimulated the release of dopamine, which in turn prompted growth in the rat's postsynaptic neuron of an increased number of dendritic spines

What happens when Natalie learns this new skill?

When Natalie learns this new skill, her neurons are forming new connections with each other. This process is called

Which part of the brain is involved in memory?

The cerebral cortex is involved in learning and memory storage. Recognition of stimuli - the association areas related to the sensory modality of the stimulus are involved in this form of learning. For example, previously encountered visual stimuli, such as recognising someone you have met before, are stored in the visual cortex. However, we often have several senses involved in a memory, so the relevant areas are linked.

What neurotransmitter is involved in learning?

in learning the key neurotransmitters are glutamate and dopamine. Glu tamate is an excitatory neurotransmitter that causes the postsynaptic neuron/s to fire. It also aids development of change at the synapse by stimulating the release of dopamine which activates the growth of dendritic spines.

What happens when neurotransmitters are passed across a synaptic gap?

The neurotransmitters only lock into sites that are receptive to that particular neurotransmitter. Once the message has been passed across the synaptic gap it causes the next neuron to fire (excitatory) or prevents that neuron from acting (inhibitory).

What is the relationship between stimulus and response?

relies initially on the automatic association between a particular stimulus and a response. A previously unrelated stimulus is then paired with the original stimulus and learning becomes evident when the new stimulus results in a similar response to that given to the original stimulus.

What is the hippocampus involved in?

The hippocampus is involved in learning that is evident in declarative memories and spatial memories. Damage to the hippocampus results in the emotional responses involved in learning remaining intact, but the 'declarative' being lost.

What happens when neuronal connections are strengthened?

If neuronal connections are strengthened by the release of more glutamate (a functional change) new synapses will form (a structural change). Neurons will eventually 'wire' together

Why do synapses change?

Changes at the synapse due to learning

How long does sensory memory last?

8. How long does information last in sensory memory? 20 to 30 seconds a fraction of a second to several seconds 5 minutes 1 to 2 minutes

How many slides were shown in Ralph Haber's study?

2. Participants in a study conducted by Ralph Haber were shown more than 2,500 slides of faces and places for only 10 seconds each. Later, they were shown 280 of these slides, each paired with an unseen slide. What percentage of the slides they had seen before were the participants able to recognize? 100 percent 90 percent 60 percent 75 percent
