Types of epilepsy and the mechanisms that cause seizure

/0 Comments/in /by
You are studying different types of epilepsy and the mechanisms that cause seizure activity. While researching, you find that it’s usually caused by a mutation in different types of sodium channels. Please answer the following prompts.

 

  1. The first mutation causes voltage-gated sodium channels to recover from inactivation faster. How would this impact action potentials and firing rate? If this mutation causes seizures, would these channels be found on GABAergic or glutamatergic neurons? Explain.
  2. The other mutation causes voltage-gated sodium channels to open at a more positive membrane potential. How would this impact action potentials and firing rate? If this mutation causes seizures, would these channels be found on GABAergic or glutamatergic neurons? Explain.

Sequence of events in synaptic transmission

/0 Comments/in /by

Organize the sequence of events in synaptic transmission. Action potential arrives at synaptic bouton 1 2 3 4 Neurotransmitters bind to specific receptors on the postsynaptic membrane. voltage-gated calcium channels open. Diffusion causes an influx of calcium. Calcium-dependent proteins are activated, causing synaptic vesicles to fuse with the presynaptic membrane. EPSPS, IPSPs, or metabotropic responses occur. Synaptic transmission is rapidly stopped
