Hi there ,

We don't have sufficient researches done to completely prove the fact that Brain

Function is hereditary.

However , as of a research conducted in 2003, there is a gene variant of BDNF

(Brain Derived Natriuretic Factor ), which is heritable and  this has some influence on Brain functioning, especially memory. Interestingly, there are like 20-22 genes which are assumed to have hereditary influence on Brain Functioning. Till date

we are sure that environment does play a role in genetics make up of a brain (for

example exposure to cigarette can result in certain gene mutations resulting in reduce brain function) but how much hereditary has an influence, still remains

a question.

I hope this will helpful

Hello candidate

A new study suggests that a subtle genetic difference may be responsible for some of the normal variation found in human memory and learning function.

Researchers identified two different inherited forms of a gene vital for learning and memory, known as BDNF ( brain (https://www.webmd.com/brain/picture-of-the-brain) -derived neurotrophic factor). They found people with one version of this gene performed better on a memory and learning test.

In addition, laboratory tests showed people with the other form BDNF did not process a BDNF-related protein normally, which might explain some of the memory-related problems.

You can refer to the publications of medical researches backed by the Government India from https://www.google.com/url?sa=t&source=web&rct=j&url=https://pubmed.ncbi.nlm.nih.gov/15325958/&ved=2ahUKEwjKz9Tm_o_1AhXrSmwGHUKaDCsQFnoECBoQAQ&usg=AOvVaw2HPA9U1fiGvP0YQCVX5vFF

Hope that helped. All the best.
