Answer:
The correct answer is: Brain-derived Neurotrophic factor.
Explanation:
The brain-derived neurotrophic factor (commonly abbreviated to BDNF) is a protein from a family related to the growth of nerves that also works as a neurotransmitter.
In the brain, the BDNF is active in areas like the <u>basal forebrain, the cortex, and the hippocampus</u>, where learning, memory, and higher thinking take place.
BDNF plays a<u> key role in the survival of neurons and the process of synaptogenesis</u>, which is why the decrease of this protein is linked to several neuropsychiatric conditions like depression and schizophrenia.
