One example of an animal without a brain is the cnidarian Hydra, which has a simple nervous system consisting of a nerve net with diffuse nerve cells located throughout its body. Despite lacking a brain, Hydra is capable of performing complex behaviors, such as responding to light and touch stimuli, and capturing prey using stinging cells called nematocysts. Other examples of animals with simple nervous systems include sea anemones, jellyfish, and flatworms.
Thank you Dr. Swamy for your nice & informative video..appreciated from Bangladesh..👍

Nice lecture
Sir, impulse transferred from terminal to dentrite of other neuron right?
Fabulous lecture sir ,but please blackboard use so batter understand good luck
Sir plz make a lecture series in insect HEAD, THOREX ,ABDOMIN ,and LEG
Sir my presentation topic is physiology of nervous system of insect so please suggest which topics should I cover in my presentation.
Mode of Impulse conduction
Thankyou sir 😊
Which system of insect needed to attack to control insect pest
Potassium does not carry negative charge !
Jelly fish sir
Which one?
@@DrKalleshwaraswamyCM animal without brain sir
sir, sponges do not have brain
You are rite..
