Questions and Answers

Which type of memory is involved in remembering things in space?

  • Spatial memory (correct)
  • Working memory
  • Declarative memory
  • Hippocampal memory

    • What is the function of glutamate receptors in long term potentiation (LTP)?

  • They let in calcium or sodium positive ions (correct)
  • They create more avenues for neurotransmitters to come in

  • They release glutamate into the synaptic cleft

    • What happens during long term depression (LTD)?

  • Glutamate receptors are activated
  • Neurons fire at different frequencies
