1. What is the LTP feature of specificty?

  • ONLY synapses active during the stimuation have increased responses and other pathways to the same neuron are not.
  • When synapses active during the stimuation have increased responses the surrounding cortical areas have decreased esponses
  • Synapses active during the stimuation have increased responses aswell as other pathways to the same neuron
  • Synapses active during stimulation show decreased responses when surrounding cortex is activated
