Effects of removal and regeneration of the suprapharyngeal ganglion on learning, retention, extinction and negative movements of Lumbricus terrestris were studied in a T maze with electrical punishment and a sandpaper cue at the incorrect side and a dark goal box at the correct side. Learning, retention and negative movements at the choice point were not affected by ganglionectomy or regeneration. Extinction was prolonged, and negative reactions to the sandpaper were increased, by ganglionectomy after training. Negative movements in the maze stem were decreased by ganglionectomy under both learning and extinction conditions, and increased abruptly after 30--50 days of postoperative training. Reactivity to shock decreased when ganglionectomy followed, but not when it preceded, learning. Frequency of correct turns was the only measure clearly changed by learning. Negative movements at the choice point tended to decrease, but inconsistently during learning. There was no evidence that discrimination of sandpaper contributed to learning. Ten trials per day produced fatigue but was not detrimental to health or vigor.

The Ganglia is a part of the nervous system The Ganglia is a mass of nerve tissue existing outside the central nervous system. To make a long story short it's a brain. …
It works as the brain and is part of the nervous system
Ganglia are bundles of nerves that are found in the peripheral nervous system. Ganglia function to connect neurological structures and send messages between them.
Ganglia are clusters of nerve cells. They are mostly associated with the sympathetic division of the autonomic nervous system in vertebrates, where their functions are p…articularly related to the activities of the heart, glands, and involuntary muscles..
It is a mass of nerve tissue existing outside the central nervous systems
The segmental ganglia is part of the nerves system. Ganglia's are paired and connect all the way down the nerve chord.

They're used for farming because their cast is good for the soil
The ganglia is a concentration of nerves, analogous to the brain, best used for coordination.
An earthworm eats dirt, and then when it passes through it's system and "out the other end" it is now fresh fertilizer that is really good for your garden!!!
to annoy us as we try to figure out what it is
The abdominal ganglia innervate the organs, genitalia, and cerci.
The pedal ganglion supply nerves to the foot muscles of mollusks.
The Ganglia is a part of the nervous system The Ganglia is a mass of nerve tissue existing outside the central nervous system. To make a long story short it's a brain.
The ganglia works as the brain because there is a series of connected nervous cords that are located in the anterior part of the worm.
The function of ganglia in the human body is to get information from the photoreceptors and collectively transmit image-forming and non-image forming visual information from t…he retina to regions in the brain.
