lecture 2 Flashcards
(25 cards)
engram
the way a memory is kept in the brain
anterograde amnesia
when a person cannot form new memories after a brain injury, but they can still remember things from before the injury
episodic memory
the type of memory that helps you remember personal experiences or events, like your last birthday or a vacation you went on
semantic memory
the type of memory that stores general knowledge and facts, like knowing that Paris is the capital of France or that dogs are animals
standard consolidation theory
the idea that new memories are first stored in the hippocampus, but over time, they move to the neocortex for long-term storage.
neocortex
the outer part of the brain
retrogade amensia
when a person loses memories from before a brain injury or trauma. They may forget past events, personal experiences, or facts they once knew, but they can often still make new memories after the injury
source amnesia
when you remember information but forget where, when, or how you learned it
elaborative rehearsal
a memory technique where you link new information to things you already know to help remember it better and longer.
semantic encoding
the process of storing information in your memory by focusing on its meaning.
Which brain region is crucial for the consolidation of episodic memories?
hippocampus
fornix
a fiber bundle that connects neurons from septum to hippocampus
neuron doctrine
the concept that the nervous system is made up of neurons
engram
the way a memory is kept in the brain
visual cortex
info not just available when you see it but also moments later, for future recognition
hippocampus
Forms and stores new long-term memories
executive function
protecting memory from interference
Context-dependent memory
You’re more likely to recall information if you’re in the same context as when you learned it.
State-dependent memory
Recall is also influenced by your internal state
plasticity
the brain’s ability to change and adapt by reorganizing its structure, function, or connections in response to experience, learning, or injury.
Depolarization
a neuron is more likely to fire an action potential
hyperpolarization
a neurons is less likely to fire an action potential
memory formation
the forming of memories
encoding
Taking in information
