| Abstract |
This is an account of a whole brain preparation that has enabled us for the first time to dye-fill, and record intracellularly from, cells in the brain of Octopus. Over a hundred cells in the posterior chromatophore lobes of nearly 50 octopuses were penetrated. Most cells were spontaneously active, firing at 1-12 Hz, some were silent and others showed regular bursting activity. Lucifer Yellow fills confirmed that many cells in this lobe are unusual by invertebrate standards in having cell body 'dendrites' as well as axonal processes with branches. Many cells are also dye-coupled. This new preparation could be modified for longlasting intracellular recording in many lobes of the brain of semi-intact cephalopods. |
