Questions and Answers

What happens when information is transferred to long-term memory?

  • It is stored in several regions across the brain (correct)
  • It is processed by the synapses
  • It is converted into electrical energy
  • It remains in short-term memory indefinitely

What happens when two neurons communicate repeatedly?

  • They stop communicating altogether
  • The efficiency of communication between them increases (correct)

Study Notes

Memory Formation and Storage

  • Information is first stored in short-term memory after initial exposure, retaining data temporarily for quick recall.
  • The hippocampus plays a crucial role in memory formation by consolidating short-term memories into long-term storage.
  • Once information is transferred to long-term memory, it becomes stable and accessible for future retrieval.

Neural Communication

  • When two neurons communicate repeatedly, synaptic strengthening occurs, enhancing the efficiency of transmission and contributing to learning.
  • Neurotransmitters facilitate communication between neurons at dedicated synaptic sites, transmitting messages through chemical signals.
  • Conversion of experience into a pulse of electrical energy occurs during synaptic transmission, allowing neurons to process and relay information.

Information Storage

  • Initially, experiences are stored in the brain's hippocampus before being integrated and consolidated into long-term memory.
  • Following consolidation, information is finally stored throughout the brain's neocortex, leading to a comprehensive memory network.
