Our specialized neurophysiology framework
Electroencephalography / EEGCerebral activity.
Cerebral activity.
Measured in context.
EEG characterizes cerebral bioelectrical activity through carefully acquired scalp recordings.
Understand what a recording evaluates, how signal quality matters and where the findings fit within the referring clinician’s assessment.
A recording supports evaluation. It does not, by itself, establish a diagnosis.
EMG & nerve conduction studiesNerves and muscles.
Nerves and muscles.
Complementary perspectives.
Nerve conduction studies evaluate selected peripheral nerve responses. Needle electromyography offers a different perspective on skeletal muscle and motor-unit physiology.
These methods are complementary, not interchangeable. Their clinical meaning depends on the broader history, examination and evaluation.
Needle EMG requires appropriately qualified licensed professional performance; technical acquisition is not independent medical interpretation.
03 / Specialized neuromuscular & reflex physiologyFocused methods.
Focused methods.
Distinct pathways.
Neuromuscular transmission, late motor responses and reflex circuitry require different acquisition methods—and careful clinical context.

Different stimuli.
Distinct neural pathways.
Somatosensory, visual and auditory methods each answer a different physiologic question. Their responses support—not replace—broader clinical assessment.
