This LTP is a form of. Synaptic strength describes the magnitude of post-synaptic currents or potentials in response to a pre-synaptic action potential. The resting membrane potential is the separation of the relative positive and negative charges across the membrane of a cell at rest.

Sodium ions diffuse through leakage channels into the cell but potassium ions diffuse through leakage channels out of the cell 2. For example high-frequency discharges in pre-synaptic fibers and concomitant strong synaptic activity may lead to a long-lasting increase in synaptic strength. Drag the charges to the correct side of the membrane to represent the resting membrane potential of a typical neuron.

Which of the following events in a biological membrane would not be energetically favorable and therefore not occur spontaneouslyA. There is one set of voltage-dependent channels that are specifically permeable to Na ions and. The remaining two types of ion channels which are the ones responsible for generating the action potential are both voltage-dependent ie.
