Neurotrans/Neuromod

Question 1

Most synaptic communication in brain is accomplished by

Answer 1

Amino acids that function as NT: glutamate (EPSP) and GABA (IPSP)

Question 2

With exception of pain, all sensory organs transmit info to where and through what?

Answer 2

5. with the exception of pain, all sensory organs transmit information to the brain through axons whose terminals release glutamate (pain is a peptide)

Question 3

Most local circuits in the brain involve balance between what?

Answer 3

Excitatory and inhibitory influences and is responsible for most of the information transmitted from place to place in the brain

Question 4

There are many NT in the brain (several dozen), what are their roles?

Answer 4

• To modulate and regulate the information transmission of the glutamate/GABA circuits
• Release of NT other than glutamate or GABA activates or inhibits circuits of neurons that are involved in particular brain functions
