The Hoffmann reflex (H-reflex) is an electrically induced reflex that bypasses the muscle spindle. H-reflex is a useful measure to assess modulation of monosynaptic reflex activity in the spinal cord.
H-reflex studies can be set up multiple ways and users should determine the best approach for their required protocol; BIOPAC cannot recommend a “standard” approach for H-reflex.

The ERS Evoked Response Smart Amplifier is an extremely low noise differential amplifier that accurately amplifies very small potentials, such as those associated with stimulus/response, startle response, ABR auditory brainstem response, somatosensory evoked response, signal-averaged recordings, and nerve conduction velocity recordings. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by […]
View AllThe mind and body work together in many ways and psychophysiology research provides insight to these connections. BIOPAC has a variety of systems to power your emotion, arousal, stress, cognitive assessment, group interaction, startle, and other psychophysiology research. Here are some recent studies that have used BIOPAC systems for psychophysiological research… Skin conductance, facial EMG, […]
