First excitation | First inhibition | Second excitation | Second inhibition | |
---|---|---|---|---|
Number (fraction) | 89 (98.9%) | 44 (48.9%) | 53 (58.2%) | 9 (9.9%) |
Latency (ms) | 10.4 ± 5.6 | 12.7 ± 6.5 | 32.5 ± 16.2 | 42.7 ± 25.4 |
Duration (ms) | 11.1 ± 11.1 | 5.8 ± 9.1 | 9.9 ± 14.0 | 3.3 ± 2.9 |
Values are shown as mean ± SD. Approximately half of the recorded neurons displayed only excitation in response to HVC stimulation, whereas the other half displayed excitation followed or preceded by inhibition.
