Document Summary
Synaptic depression v. facilitation: decreases in neurotransmitter release, causing a decrease in the post synaptic cell. Learning: acquisition of new information or neurotransmitter release, causing an increase in knowledge and a change in behavior as a result the post synaptic cell. Memory: retention of learned info, ability to store or recall past experiences. Classical conditioning: type of associative learning where innate response is expressed in. Hippocampi of taxi v. bus drivers: posterior response to a neutral stimulus hippocampus was larger in taxi drivers. Conditioned stimulus: learned stimulus was larger in bus drivers. Hebb"s postulate: theory that says coordinated pre and post response strengthens synapse. Different gating properties: ampa requires only glutamate receptors that open. Magnesium block: ion that blocks the nmda requires glutamate and depolarization to receptors, moved when depolarized open. Activation allows what different ions to and ndma enter the neuron.
