Any physiological action that receives a positive feedback, such as a handshake, a kiss, or the use of a drug, can cause the level of dopamine activity in the brain to increase. Dopamine is a neurotransmitter that relays messages from one neuron to the next. Through axons, neurons influence neurological activity in many regions, spec...

Dopamine Making Neurons Substantia Nigra Spider
367 wordsInsects have sensors (force-sensitive organs) concentrated in areas near joints, tips of the legs, and near exoskeletal sites attached to muscle tendons. These sensors act as strain gauges to detect compression of the exoskeleton. Using this information, insects recognize environments, regulate walking movements, and astonishingly remember stepping patterns and location. Through memory experiments, scientists see that a spider memorizes its own previous walking movements to backtrack to a fly. A...
