Brain Products offers integrated solutions designed to combine EEG with brain stimulation techniques like TMS and tES to demonstrate causality in neuroscientific research. Their hardware features low-profile active electrodes and high-sampling-rate amplifiers that facilitate close coil positioning and rapid artifact recovery. Additionally, their systems support closed-loop experiments by providing ultra-fast data access, making them suitable for sophisticated research paradigms that require real-time interaction between brain activity and stimulation. Slim, low-profile active electrodes allow for close proximity between stimulation coils and the scalp., High sampling rates in all-in-one amplifiers ensure fast recovery from stimulation-induced artifacts., Data servers provide ultra-fast access to recorded signals, enabling the implementation of closed-loop experimental designs., Specialized hardware, such as the actiCHamp Plus and BrainAmp MR, is recommended for high-performance combined EEG and stimulation setups., Integrated software solutions like BrainVision Recorder allow for seamless signal management and triggering during stimulation protocols.
