In this example, we show that seizures can be elicited in a simple system. Exposure to a common convulsant agent caused a stereotyped and concentration dependent sequence of behavioral changes. These changes included an increase in immobility time, a decrease in swimming speed, and a reduction in locomotor activity.
In addition, these changes were accompanied by a change in gene expression in several brain regions, including the hippocampus, amygdala, hypothalamus, striatum, thalamus and cerebellum. The results suggest that the induction of seizure-like behavior is a result of the activation of a specific subset of brain circuits involved in learning and memory.
What is fish stroke?

Why does my fish look like its having a seizure?
The symptom of smying is not a single disease, but an indication that the fish has lost control of its muscles and nerves. It happens when fish are stressed most often because of over-fishing. The most common cause of shimmy is stress.
Stress can be caused by a number of factors, such as a sudden change in the water temperature, a change of the fish’s environment, or a lack of food. The fish may also be stressed by the presence of other fish in its environment.
In some cases, stress may be the result of a disease that has been passed from one fish to another. A fish that is stressed may not be able to cope with the stress of being in a new environment and may become disoriented.
This can lead to a disorientation that can result in fish disobeying their natural instincts and swimming away from the source of their distress.
Do fish have heart attacks?
It is made up of two main parts, the left ventricle (the heart’s pumping chamber) and the aorta, which is a tube that carries blood from the heart to the lungs.
The heart muscle is responsible for pumping blood to all the other organs in your body, including the brain, lungs, kidneys, liver, spleen, stomach, intestines, pancreas, gallbladder, uterus, ovaries, testicles, skin, eyes, ears, nose, tongue, hair, nails, fingernails, feet, fingers, toes, ankles, knees, elbows, wrists, shoulders, back, neck, arms, chest, abdomen, pelvis, legs and feet.
Why is my fish twitching?
A fish’sstic movements are part of its behavior. It is caused by stimulation such as water flow and vibrations from the aquarium filter. It can be a result of stress or hunger. If you don’t have enough fish food in your tank, they will twitch to find something to eat. This is a sign that you need to add more food to the tank.
If you have a lot of fish, you may find it difficult to keep them all in the same place. You may have to move some of them around to get them to stay in their natural habitat. The best way to do this is to place them in different areas of your aquarium.
Can fishes drown?
The majority of fish breathe when water moves across their gills. The gills can be damaged if water cannot move across them. They don’t technically drown, because they don’t inhale the water, but they do die of suffocation.
The fish that are most at risk of drowning are those that live in water that is too shallow for them to reach the surface. These fish are also the ones most likely to be caught by anglers who are trying to catch them in shallow water.
What’s the fastest stroke?
Swimming statistics show freestyle remains the fastest stroke, according to world records posted on USAswimming.com, followed by butterfly, backstroke and breaststroke, the latter of which is the most popular in the United States.
Do flashing lights cause epileptic seizures?
For about 3% of people with epilepsy, exposure to flashing lights at certain intensities or to certain visual patterns can trigger seizures. This condition is known as photosensitive seizure. It is more common in children and adolescents. As you get older, it becomes less frequent.
Can betta fish have heart attacks?
Fish have nervous systems and are fully capable of experiencing a seizure; fish can even have heart attacks, strokes, or experience other life-threatening conditions. In the wild, these fish are often hunted for their fins, which are used in traditional Chinese medicine to treat a wide range of ailments. In captivity, however, the fins are not used for medicinal purposes, but are instead used as a source of income for the fish’s owners.
