Afferent

adjective Referring to the centripetal movement of blood or nerve impulses—e.g., through the veins toward the heart, or nerves to the brain.
noun A blood vessel or nerve that centripetally conveys flow or an impulse.

afferent

adjective
1. Conveying or transmitting.
2. Referring to the movement of blood or nerve impulses centrally–eg, through vessels toward the heart, or nerves to the brain, Cf Efferent.

Afferent

Refers to peripheral nerves that transmit signals to the spinal cord and the brain. These nerves carry out sensory function.

Q. where do depression comes from?

A. Depression is very common, and at least 16% of the population is said to experience an episode of depression at least once in their life. It is known that genetic predisposition has a lot to do with developing depression and other psychiatric disorders such as anxiety, but the exact gene is unknown and some triggers may influence a person to have a depressive episode even if there is no one in their family who is suffering from it (for instance- stress, work and needing to deal with trauma or distress).

Q. How come it’s possible? my child with autism is undergoing different therapies for many years……recently I got the information that he may have got autism by maternal antibodies ……how come it’s possible?

A. There are many triggering reasons for autism like metabolic, genetic, and environmental. Now it can also get triggered by maternal antibodies. The maternal antibodies which crosses the placenta, can affect the brain tissue of the fetus which can adversely affect the baby`s brain development & cause autism.
