Genes that cause epilepsy do so by altering:
A) GABA receptors.
B) acetylcholine levels.
C) the arrangement of blood vessels in the brain.
D) the shapes of astroglia cells.

Question

Quizplus · Accepted Answer

The neurotransmitter GABA is an important inhibitor of neuronal activity, and alterations in GABA receptors can lead to increased neural excitability, which is a hallmark feature of epilepsy.

Answer: B 
 While acetylcholine is important for various cognitive processes, there is no known direct link between acetylcholine levels and epilepsy.

Answer: C 
 The arrangement of blood vessels in the brain may indirectly impact the likelihood of seizures, as disruption of blood flow or oxygen supply can cause neural damage that may lead to epilepsy. However, genes that cause epilepsy more directly affect neural activity and signaling, rather than blood vessels.

Answer: D 
 Astroglia cells are a type of glial cell in the brain that support and nourish neurons. While they are known to play a role in modulating neuronal activity, there is currently no direct evidence linking their shape or function to the development of epilepsy.
