How Does The Brain Store and Retrieve Memories?

The video explains memory as a process involving neurons and synapses in the brain. It covers how memories are encoded through perception and stored in short or long term memory. The hippocampus plays a key role in deciding what to remember. Neurons communicate via synapses, forming a vast network. Short term memory is limited, while long term memory has unlimited capacity. Memory retrieval involves accessing unconscious storage. Challenges in memory include faulty encoding. The study of memory is ongoing, with much still to learn.

What is the initial step in memory processing that involves the senses?

• Retrieval

• Storage

• Encoding

• Analysis

How do neurons communicate information within the nervous system?

• Via an electrochemical process

• Through chemical reactions

• Using magnetic fields

• By direct contact

What role do synapses play in the brain?

• They destroy old neurons

• They store memories

• They connect nerve cells and transfer information

• They create new neurons

What is the capacity of short-term memory?

• Unlimited

• Limited to sensory inputs

• About 7 items for 20-30 seconds

• 100 trillion synapses

Which type of memory is rapidly acquired but also rapidly lost?

• Sensory memory

• Short-term memory

• Conscious memory

• Unconscious memory
