1. causing or relating to an increase in the electrical potential difference across a cell membrane
Usage: biology, neuroscience

1. to increase the electrical potential difference across a cell membrane, making the inside more negative relative to the outside
Usage: biology, neuroscience; present participle or gerund form of 'hyperpolarize'

Examples

• The hyperpolarizing current made the neuron less likely to fire an action potential.
• Certain ion channels are responsible for hyperpolarizing the cell membrane after stimulation.
• A hyperpolarizing stimulus can suppress neural activity in the brain region.
• The researchers applied a hyperpolarizing voltage to study the cell's response.
• Hyperpolarizing the membrane increases the threshold needed to trigger an action potential.
