Overview

This video explains the biological processes of the brain related to learning and memory. It recaps concepts like embryonic development, neuronal plasticity, and the "use it or lose it" principle, then elaborates on memory formation, distinguishing between short-term memory (hippocampus, ~30 seconds, ~7 items) and long-term memory (cerebral cortex, permanent storage), and how information is transferred between them.

Key takeaways

• Brain Development: The brain begins developing embryonically before birth, forming connections called synapses.
• Neuronal Plasticity: Synapses can change based on activity. Increased signaling strengthens connections and memories, while decreased signaling leads to memory loss ("use it or lose it").
• Memory Formation: Learning involves two main types of memory:
  • Short-Term Memory (STM): Stored in the hippocampus for about 30 seconds, holding approximately 7±2 pieces of information. Information can be released or transferred to long-term memory.
  • Long-Term Memory (LTM): Stored permanently in the cerebral cortex. Information can be recalled from LTM back to STM for active use.
• Learning Process: The brain promotes learning by strengthening synaptic connections, facilitating efficient transmission of information to LTM and back to STM, which is crucial for processes like studying for exams.
