No it is not. It is there in stratosphere.
it's separate and not together so it would be a separate layer
A basic neuron in a neural network is a computational unit that takes input values, applies weights to them, sums them up, adds a bias, and then passes the result through an activation function to produce an output. This output is then passed to other neurons or to the network's output layer.
In the neural layer of the retina, the arrangement of neuron populations from the pigmented epithelial layer to the vitreous humor includes photoreceptor cells (rods and cones) → bipolar cells → ganglion cells. These neurons are interconnected through synapses that transmit visual information from the photoreceptor cells to the ganglion cells, which then send the information through their axons as the optic nerve to the brain for processing.

Neural tissue originates from the ectoderm layer of the developing embryo. This layer gives rise to the neural tube, which later differentiates into the central nervous system (brain and spinal cord) and the peripheral nervous system. Neuromesodermal progenitors are involved in the development of both neural and mesodermal tissues during embryonic development.

Melanocytes are derived from the neural crest, which is a transient embryonic structure that forms from the ectoderm germ layer.
The neural tube is the part of the development of the central nervous system in a developing embryo. What is pretty amazing about this is that within the first 4 weeks of development from conception, the entire framework of the central nervous system will have finished forming! Around day 18, the neural plate appears at the midline of the thickening of the ectoderm, the outermost layer of the germinal sac. Essentially what happens over the next couple of days is that the neural plate forms a depression, which eventually is pushed down and separated from the original cell layer by the fusion of the neural crests, resulting in the formation of a neural tube - this is rather hard to explain without a proper diagram!

False.
The ectoderm layer of the embryo gives rise to the tissues of the nervous system through a process called neurulation. During neurulation, the neural tube forms from the ectoderm, which eventually gives rise to the brain and spinal cord. The cells within the neural tube differentiate into various types of neural cells that make up the nervous system.

The retina is responsible for transducing light into neural impulses. It is a layer of tissue located at the back of the eye that contains photoreceptor cells (rods and cones) that convert light into electrical signals that can be processed by the brain.
