DISCUSSION SCENARIOS

Tsepiso accidentally stepped on a sharp nail; she suddenly jumps into the sky away from the nail. Use your understanding of the Neuroscience psychology to explain Tselios’s behaviour.                 

Shortly after he was born, Jacob's arms and legs started jerking every 20 minutes. Weeks later; he could not focus on his mother's face. The diagnosis was uncontrollable epileptic seizures involving his entire brain. He underwent brain surgery at 5months in which 20% of his brain was removed.
Do you think the surgery was successful in treating the seizures and why?

  1. i don't think Jacob's brain surgery succeeded because since the brain is a very delicate and sensitive organ to temper with, removing some of its part will definitely lead to loss of his life.

    1. consider the properties of nerve cells, neuroplasticity

    2. Ok scientists say that the brain can undergo what we call a regenerative process whereby new brain cells are created as the person grows, and also after injury/surgery the brain is able to share its functions within the remaining areas. So maybe Jacob might have survived but is it true or its a myth?

  3. when tsepiso steps on the nail the afferent neuron sends message to the central nervous system (CSN) it interprates the message and via the efferent neuron sends it to the affected part therefore making tsepiso respond by jumping.

    1. Good response. However consider the role of interneurons, sensory receptors and the muscles. And note that CNs interprets the stimuli and send the response via the efferent neuron.

    2. so do the efferent neurons and cns respond to stimuli only?

    3. efferent neurons just transport the response.

    4. C Nervous system interprets the stimuli and give an appropriate response

    5. the sensory receptors detected the stimulus and impulses were sent to the brain by the sensory neurons whre it ws interpreted then the response frm the brain ws sent by the motor neurons to the muscles the muscles consequently contracted

    6. Well done Komeke. To add on to that tell us about the role of interneurones and what happens when the muscles contracts and it becomes complete

  4. The role of Interneuron is to pass or transmit the impulse from the afferent to the efferent and vice versa. so the muscles contract to pull away the body organ from the danger,hence tsepiso is jumping up.
