Factors that can affect transfer of information from STM to LTM

Lösung anzeigen
TESTE DEIN WISSEN

1. emotional state - best if alert, motivated, surprised, and aroused 

2. rehearsal - repetition and practice 

3. association - trying new information with old memories 

4. automatic memory - subconscious information stored in LTM

Two stages of storage 

Lösung anzeigen
TESTE DEIN WISSEN

Short term memory : (STM or working memory) temporary holding of information ; limited to seven or eight pieces of information 


Long term memory : (LTM) has limitless capacity

List of Molecular Mechanism For Learning

TESTE DEIN WISSEN
  • Altered mRNA is synthesized and moved to axons and dendrites 
  • Dendritic spines change shape
  • Extracellular proteins are deposited at synapses involved in LTM 
  • Number & size of presynaptic terminals may increase 
  • More neurotransmitter is released by presynaptic neurons

TESTE DEIN WISSEN

persistent strengthening of synapses based on recent patterns of activity

TESTE DEIN WISSEN

Hebb's rule

Lösung anzeigen
TESTE DEIN WISSEN

If a pre-sypnaptic cell has action potentials just preceding action potentials in a post-synaptic cell then the synaptic connection between the two cells will be strengthened. In contrast, if the timing of action potentials in the-synaptic cells are not correlated in time, then the strength of the synaptic connection between the two cells will decrease.
