Cellular Changes and Learning • Learning and Memory is measured by observing behaviour • Cellular changes specific changes in neurons alters the nervous system change in behaviour • Therefore learning and memory are a result of changes in behaviour and are therefore linked to changes in the cellular level • So what are the cellular changes?
Changes at the Cellular Level Bring About Synaptic Plasticity • Synaptic plasticity: alterations of synaptic connections between neurons, which subserves learning and memory • Neuron to neuron communications are made possible by synapses • At the synapse, neurotransmitters are released in response to excitation of the presynaptic neuron, which then diffuses across the synaptic cleft, binding to receptors on the postsynaptic cell.
Memories are stored as alterations in the strength of synaptic connections between neurons in the CNS.
LTP= long-lasting change in output in response to transient input= learning TASK: • YouTube - Neuron Synapse • Read pages 354- 355 (stop at Plasticity of the Brain) • Complete page 101 of your workbook
