Summary
Experience changes brain connections, forming short-term and long-term memories.
In depth
Sensory memory lasts seconds; short-term (working) memory holds about 7 items for tens of seconds; long-term memory has declarative (facts, events) and procedural (skills) forms. Repetition, sleep and emotion strengthen memory. Patient H.M. showed the hippocampus's role.
Memory involves encoding, storage and retrieval. Forgetting may result from decay or interference. Emotional events are remembered better due to amygdala activity.
Example: mnemonic techniques use associations to aid recall.
The Atkinson-Shiffrin model has sensory register, short-term store and long-term store, with Baddeley's working memory model featuring a central executive, phonological loop and visuospatial sketchpad. Long-term memory splits into explicit (episodic and semantic) and implicit (procedural, priming, conditioning). Encoding is deeper with meaning and attention; retrieval is cue-dependent, and sleep helps consolidation. Spaced repetition and testing improve retention (the testing effect), while cramming is less effective.
Forgetting results from decay, interference and failure of retrieval; memories are reconstructive and can be distorted (Loftus's eyewitness studies). Amnesia shows dissociations: H.M. could not form new explicit memories but learned motor skills. Emotional events are remembered better due to amygdala.
Example: learning to ride a bike (procedural) persists even if you cannot describe how it works.
Frequently asked questions
What is Learning and Memory Basics?
Experience changes brain connections, forming short-term and long-term memories.
Which area of biology covers Learning and Memory Basics, and how advanced is it?
Learning and Memory Basics is one of the 54 topics in Neuroscience. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Hippocampus and Memory Consolidation, Long-Term Potentiation, Neural Circuits and Oscillations.
Can you give an example of Learning and Memory Basics?
Riding a bike is procedural memory.
What should I learn before Learning and Memory Basics?
Learning and Memory Basics is a Beginner topic, so no earlier topic is required. Other Beginner topics in Neuroscience that pair well with it include Nervous System, Neuron, Central and Peripheral Nervous Systems.

How is Learning and Memory Basics different from Hippocampus and Memory Consolidation?
Learning and Memory Basics: Experience changes brain connections, forming short-term and long-term memories. Hippocampus and Memory Consolidation: The hippocampus encodes new episodic memories and gradually transfers them to the cortex during sleep. Read both side by side and note what each one explains.
How should I study Learning and Memory Basics step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Hippocampus and Memory Consolidation and explain the difference aloud. Finally, take the Neuroscience quiz and come back to this page for any question you miss.
