Transcranial magnetic stimulation (TMS) is a noninvasive method of studying brain functions and interconnections—it causes hyperpolarization or depolarization of neurons in specific or general parts of the brain. For TMS and repetitive TMS (rTMS) studies, BIOPAC has wireless and wired solutions for EEG, ERS, and EMG. Transcranial magnetic stimulation (TMS) can be used in conjunction with fMRI and transcranial direct current stimulation (tDCS) or transcranial alternating current stimulation (tACS).
Always use carbon leads for any electrode lead that will get close to the TMS field. and always use non-metallic carbon electrodes if concurrent EEG data is required. EL-CHECK Impedance Checker is recommended for all use cases to verify impedance levels before recording so placement or connections can be adjusted if necessary to optimize signal quality.
This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.The STMISOLA will support arbitrarily long, constant, non-varying, direct output currents, so long as the associated voltage compliance is 100 VDC or less. The level is adjusted by holding a stable voltage to the control voltage input of the STMISOLA. This control voltage can be set in AcqKnowledge, to be output to STMISOLA via MP160/150 analog output.
BIOPAC is unaware of safety concerns related to this procedure, however it is our understanding that TMS is an investigative protocol. As a safety precaution, please verify output currents prior to any subject measurements. There are no known measurement impacts when performing TMS with other BIOPAC equipment.
The fEMG Electromyography Smart Amplifier is designed specifically for recording facial EMG signals and electrical activity from other small muscle groups. Use with AcqKnowledge™ software to analyze facial expressions and startle paradigms. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level […]
