Exploring Memory and Emotion

What enhances memory encoding according to scientists at Columbia University?

• A revolutionary brain implant

• Genetic modification

• A new type of neurotransmitter

• A specific neural circuit that tags information with emotional associations

What does Brian Greene's memory of eating a hot dog illustrate?

• The importance of family traditions in memory formation

• How memories can be seen in third person and modified over time

• The role of smell in triggering childhood memories

• The impact of dietary choices on memory

What is NOT a type of memory discussed?

• Reflexive memory

• Semantic memory

• Episodic memory

• Implicit memory

Which part of the brain is crucial for episodic memory?

• Amygdala

• Hippocampus

• Prefrontal cortex

• Temporal lobes

Which is NOT a function of the frontal lobes in memory?

• Encoding new information

• Organizing information for better recall

• Deciding which type of memory to use

• Storing long-term memories

What is metaplasticity in the context of memory?

• A new learning method

• A change in neuron function affecting future responsivity

• A type of memory disorder

• A memory enhancement technique

How do neurotransmitters affect neurons during emotionally charged events?

• By decreasing the neuron's electrical charge

• By increasing the neuron's size

• By altering the neuron's threshold for future responsivity

• By changing the neuron's color

What role do RNA molecules play in memory formation?

• They coordinate events to change synaptic connections

• They eliminate old memories to make space for new ones

• They repair damaged neurons

• They transport nutrients to neurons

What plays a crucial role in the preservation and alteration of memory?

• Cellular renewal

• Experience and interaction

• Brain size

• Neural firings

What is a significant threat to memory alteration?

• Cellular aging

• Experience and lack of use

• Lack of neural activity

• Overstimulation of the brain
