Abstract

1.
1. The stimulation sequence provoked by a luminous point moving in front of a column of ommatidia was simulated for the eye of Squilla mantis.
2.
2. The output from the ommatidia is transferred to one tangential, integrating fiber as graded potentials. These potentials follow a gaussian-shaped angular sensitivity function for each ommatidium.
3.
3. The tangential fiber sums the inputs as they arrive and generates a spike if the sum is above threshold at one instant of time and at one point of the fiber.
4.
4. The histograms of instantaneous frequencies of spike discharge resemble the input-pattern histograms.
5.
5. The discharge pattern changes with distance and speed of the moving spot as well for the simulations as in electrophysiological recordings, and is adapted to the size of the animal.
6.
6. The shape of the histograms (i.e. the pattern of spike discharge) is assumed to transmit the information on the position, speed and size of a moving target.

Visual inputs as muscle commands in Squilla mantis
1992, Comparative Biochemistry and Physiology -- Part A: Physiology
- 1.
  1. Excitatory junctional potentials (EJPs) of the flexor and extensor muscles in the merus of the striking appendages of Squilla mantis have been simulated.
- 2.
  2. Visual inputs from a moving target are frequency coded in integrating nerve fibers. The patterned outputs from the integrating, visual fibers were frequency compressed in motoneurons.
- 3.
  3. The outputs from the motoneurons constituted the inputs to the muscles and provided characteristic EJPs.
- 4.
  4. Contraction and relaxation of the muscles were correlated to the EJPs.
- 5.
  5. Based on the simulated EJPs in response to patterned inputs, an interpretation is given for the successive phases in the strike mechanism.
Visual input patterns correlated to behavior and habitat of the mantis shrimp Gonodactylus
1989, Comparative Biochemistry and Physiology -- Part A: Physiology
- 1.
  1. The disposition of ommatidia and optical axes in the eye of Gonodactylus is described.
- 2.
  2. The matrix of horizontal and vertical fibers on the distal lamina surface presumably sub- serves integration of a complex input pattern and transmits signals for the strike to the raptorial appendages.
- 3.
  3. The antennal scales contain two parallel nervous systems contributing apparently to the visual inputs for the strike.
- 4.
  4. Some aspects of visual behavior correlated to the strike are reported.
- 5.
  5. Computer simulations show the input patterns for points and segments moving around the eye in space.
- 6.
  6. The patterns change with distance, size, speed and position of the target.
- 7.
  7. It is hypothesized that the fiber matrix in the lamina integrates inputs and translates them into spike discharge patterns. The shape of the histograms, representing the patterns, contains the information necessary for catching a prey.
- 8.
  8. The input pattern and its variations are correlated to the behavior, the histological results and the luminous habitat of the animals.
