Document Summary
The animal responds less and less and less as you continue to touch it. However if you wait a while and then touch it again, the aplysia reacts similarly to the way it did the first time we touched it. Was used to test the effects of long term habituation and long term sensitization. Long term habituations had less neurotransmitters and terminals in the neuron. More neurotransmitters and terminals in the neuron with long term sensitization. Dishabituation example: being tricked into believing that there is a spider on your body by someone. And then being overly conscious/sensitive to any stimulus received from that part of the body. Sensitization having a close call while driving a car. Your reflexes increase and you become much more conscious and careful of your surroundings. Caenorhabditis elegans (brenner researcher): extremely simple organism (302 neurons). Placed in an agar plate (the one in bcit).
