Neurons were impaled and allowed to stabilize a few minutes before testing.
To impale cells, the electrode was penetrated into the retina until a change in membrane potential was detected.
Neurons were impaled and allowed to stabilize for about 5 min before testing.
Two cortical neurons, impaled successively (left and right) were recorded simultaneously with the same thalamocortical neuron.
Numbers in parentheses are the standard deviation and number of oocytes successfully impaled, respectively.
In one series of experiments, aliquots from each of the two lots were transferred to a perfusion chamber, and membrane potential measurements were carried out on individual impaled eggs.
Both authors agree that all plans for imperial reform impaled themselves on the fact that their implementation depended on the same overmighty estates against which they were directed.
However, after impaling a cell, the spot stimulus that evoked the largest amplitude center-mediated response was considered centered over the cell and adjustment of stimuli position was made accordingly.
