- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 80 Years
- Healthy Volunteers: t

Study Arms:
- Effects of tACS during SWS- Standard/Nested 1 (Type: ACTIVE_COMPARATOR): This is a triple cross-over with a sham control condition; the standard tACS administered first, then Nested, then sham.
- Effects of tACS during SWS- Older Adults Active 1 (Type: ACTIVE_COMPARATOR): This is a double cross-over with a sham control condition; the tACS administered first, then the sham
- Effects of tACS during SWS- MCI Active 1 (Type: ACTIVE_COMPARATOR): This is a cross-over with a sham control condition; the standard tACS administered first, then sham.
- Effects of tACS during SWS- Standard/Nested 2 (Type: ACTIVE_COMPARATOR): This is a triple cross-over with a sham control condition; the standard tACS administered first, then sham, then nested tACS.
- Effects of tACS during SWS- Standard/Nested 3 (Type: ACTIVE_COMPARATOR): This is a triple cross-over with a sham control condition; the sham tACS administered first, then nested tACS, then standard tACS.
- Effects of tACS during SWS- Older Adults Active 2 (Type: ACTIVE_COMPARATOR): This is a double cross-over with a sham control condition; the sham administered first, then the tACS.
- Effects of tACS during SWS- MCI Active 2 (Type: ACTIVE_COMPARATOR): This is a cross-over with a sham control condition; the sham administered first, then standard tACS.
- Effects of tACS during SWS- Standard/Nested 4 (Type: ACTIVE_COMPARATOR): This is a triple cross-over with a sham control condition; the sham tACS administered first, then standard tACS, then nested tACS.
- Effects of tACS during SWS- Standard/Nested 5 (Type: ACTIVE_COMPARATOR): This is a triple cross-over with a sham control condition; the nested tACS administered first, then sham, then standard tACS.
- Effects of tACS during SWS- Standard/Nested 6 (Type: ACTIVE_COMPARATOR): This is a triple cross-over with a sham control condition; the nested tACS administered first, then standard tACS, then sham.
