Magnetic Sensitive Pineal Cells in Pigeons

1982

The electrical activity of about 30% of a homing pigeon’s pineal cells can be altered by changing the horizontal or vertical component of the natural magnetic field, using two pairs of Helmholtz coils. The cells respond to a rapid and/or gradual change in the magnetic field with either excitation or inhibition. In some of the sensitive cells the responses to magnetic field changes could not be repeated.

Electrical responses of homing pigeon and guinea pig Purkinje cells to pineal indoleamines applied by microelectrophoresis

1984

The effects of microelectrophoretically applied melatonin (aMT), 5-methoxytryptophol (ML), 5-hydroxytryptophol (HL) and noradrenaline (NA) on the electrical activity of cerebellar Purkinje and other cells during both day- and nighttime were studied in urethane-anesthetized intact and pinealectomized homing pigeons and guinea pigs.
