Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.
<h3>Electrical brain stimulation</h3>
it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.
<h3>What is the purpose of brain electrical stimulation?</h3>
- Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
- Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.

Answer:
Photons
Explanation:
The retina is a thin layer (membrane) in the eye that receives light through photoreceptor cells that convert this light into chemical and nervous signals transported to the brain's visual center.
The photoreceptors in the retina are known as rods and cones. Rods detect motion and sare responsible for black and white vision, they are present in the macula. Cones on the other and, are responsible for central and color vision. <em>These photoreceptors absorb photons that trigger the membrane's potential of the cells.</em>

The correct answer is testosterone.
A chemical messenger simply refers to a hormone.
Testosterone is a lipid - based hormone. In fact, it is an anabolic steroid . Steroids are a type of lipid which has four rings of carbon atoms.
Testosterone is a hormone produced by the Leydig's cells in the testes, and which encourages the development male sexual characteristics such as deep voice, a beard, increased muscle mass and bone mass, and growth of hair on the chest.
