PMID-4997823 Activity of Pallidal Neurons During Movement
- GPe activity notably different from GPi.
- "So characteristic were the discharge patterns of units in each segment that early in the course of the experiment ti be came apparent when the electrode entered and left each segment.
- Two types of cells in GPe:
- High frequency with periods of quiet (85%)
- Low frequency with bursts.
- Only one type in GPi: continuous HF discharge, 10-100 Hz, mean 63 Hz.
- Mostly contralateral, ~ 15% ipsilateral related discharge.
- Leg and arm responding units intermixed.
- Conclusion: pallidus not involved in reflexes.
- Substantia innominata = region posterior the pallidus, contains the nucleus basalis.
- I'd really like to get recordings of this quality!
