Distinguishing between neural basis of memory and learning.
« on: October 31, 2013, 07:55:50 pm »
neural basis in memory:
a biochemical change in the brain occurs when a new memory is formed called a "memory trace"
this is when there has been communication between two neurons and when the created synapse is repeatedly activated, long term potentiaton occurs. LTP is the long lasting enhancement of synaptic transmissions which is considered to be relatively permanent and enables neurons to communicate more efficiently and at faster rates.


neural basis in learning:
in learning, the pre-synaptic neuron releases the neurotransmitter 'glutamate' from it's axon terminals where it will travel across the synapse to be recieved by the NMDA receptors on the dendrites of the post-synaptic neuron, which 'unlocks' them and has an exicitatory effect, enabling the neuron to fire. the release of glutamate then stimulates the release of dopamine (responsible for creating 'pleasure pathways') - this neurotransmitter encourages the growth of proteins in the form of filigree appendages and bushier dendrites

is there anything i've misunderstood or have forgotten to include in either memory/learning?
