Understanding Memory and Engrams

What is the primary way memories are stored in the brain?

• Across various brain regions specialized for different aspects

• In the heart

• In a single location labeled with the memory

• In the spinal cord

What term do scientists use to describe the physical trace of a memory in the brain?

• Cortex pattern

• Engram

• Memory trace

• Neuron map

How do neurons change when a memory is formed?

• They shrink in size

• They move to a different part of the brain

• They form stronger connections and develop more dendritic spines

• They become inactive

In the 2007 study, what method was used to observe memory in mice?

• X-ray imaging

• Ultrasound imaging

• Glowing protein tagging

• MRI scanning

What was the purpose of using a virus in the 2009 study on mice?

• To remove neurons from the brain

• To change the color of neurons

• To increase neuron activation and dendritic spines

• To make neurons inactive

What technique involves using light to control neurons?

• Magnetoencephalography

• Electroencephalography

• Optogenetics

• Neuroimaging

In the 2013 study, how did researchers make a mouse remember its old cage?

• By using optogenetic techniques

• By feeding it a special diet

• By playing a sound

• By changing the cage color

What is a potential future application of understanding Engrams?

• Erasing all memories

• Developing treatments for Alzheimer's and PTSD

• Making memories visible to the naked eye

• Creating new memories from scratch

What is the current limitation of memory manipulation technology?

• It is not yet precise or reliable

• It can only be used on humans

• It is too expensive to implement

• It requires a large amount of energy

What is the ultimate goal of memory research according to the video?

• To make memories last forever

• To erase all negative memories

• To fully understand and manipulate memories for better treatments

• To create a device that can store memories externally
