End-of-chapter questions 1 Outline a spinal re ex using the pain withdrawal re ex as your example. The cockroach in Figure A is proven by a symbol within the centre to point out orientation; the circle represents its head. The circular histogram in Figure B shows the initial angle of turn for cockroaches tapped on the left antenna. Figure C shows the response time (the time between touch and precise movement) for 215 trials. The circular histogram in Figure B may be divided into four 90� quadrants, starting at 0�. In an experiment to present the significance of these organs, two teams of 32 spiders were used. One group had their slit sense organs intact and the opposite group had them temporarily damaged. Both teams were temporarily blinded so that so they could not see the place they were going. The spiders were placed within the centre of a grid and the starting angle that every spider took to nd the house y again was recorded, with 0� leading directly to the house y and 180� being in the opposite direction|the different way|the wrong way} to the house y. Small plates were placed on a desk and di erent wavelengths of light were used to illuminate them. Bees were tested individually to nd whether they selected the plate with the reward with each successive trial.
