22 Questions
Which protein is responsible for the weakening of neighboring synapses when one synapse strengthens?
Protein Arc
What did the researchers at the Picower Institute for Learning and Memory at MIT demonstrate in their study?
How synapses strengthen and weaken in neurons
According to Mriganka Sur, what is the relationship between collective behaviors of complex systems and simple rules?
They always have simple rules
Which technique did the researchers use to activate plasticity in the visual cortex of mice?
Changing the receptive field of a neuron
What is the name of the technique used to genetically engineer the neurons in the mouse's visual cortex?
Optogenetics
What did the researchers observe when they reopened the previously closed eye of the mouse?
Synapses related to the closed eye strengthened
What is the role of the protein Arc in synaptic plasticity?
To maintain a balance of synaptic resources
According to the study, why was it previously unclear how the mechanisms identified are actually implemented in the complicated circuits that function inside a brain?
Because previous studies were carried out in reduced preparations with artificial stimuli
According to the study, how does the strengthening of synapses affect Arc?
It weakens Arc
What is the role of Arc in neuronal circuits, according to the study?
It weakens synapses
What funding sources supported the research mentioned in the text?
All of the above
Which term best describes the flexibility of our brains?
Plastic
What happens to immediately neighboring synapses when one synapse strengthens?
They weaken
How does Mriganka Sur describe the relationship between collective behaviors of complex systems and simple rules?
They are interdependent
According to the study, why was it previously unclear how the mechanisms identified are actually implemented in the complicated circuits that function inside a brain?
The researchers lacked advanced imaging and genetic tools
What does the study suggest about learning and memory at the individual neuron level?
Learning and memory occur through the repeated simulation of another neuron
What did Ania Majewska, associate professor of neuroscience, say about the study's impact?
The study provides clues about how neuronal circuits develop and remodel in a physiological setting
What funding sources supported the research mentioned in the text?
All of the above
What is the technique used by the researchers to change a neuron's receptive field in the visual cortex of mice?
