What is tACS?
Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique that modulates neural activity.
How does EEG work?
EEG measures electrical activity in the brain through electrodes placed on the scalp, providing high temporal resolution data.
What are the key considerations for this setup?
Key considerations include proper electrode placement, monitoring impedance, and ensuring good contact with EEG gel.
Can this protocol be adapted?
Yes, the protocol can be adapted for different electrode montages and cortical targets.
What are the implications of concurrent tACS and EEG?
This method helps in understanding the immediate neurophysiological effects of tACS and its impact on brain dynamics.
