An instrument for stable single cell recording from pulsating human cerebral cortex.
An instrument has been developed for positioning microelectrodes near neurons in the exposed pulsating cerebral cortex of man or animals. The electrode moves with the cortex and maintains a fixed relationship with the desired neuron. Stable extracellular single cell recordings have been obtained for 17.5 min from an exposed human brain that pulsated 1.5 mm at the surface.
