Hello, my friend. Is it true that what goes from my sensory instruments of the human body to my brain is only electrical signal?

Hello! Yes, it's true that what your brain receives from your sensory organs—like your eyes, ears, skin, etc.—are electrical signals. Here's a brief overview of how this works:
Sensory Detection: Your sensory organs detect stimuli from the environment. For example, your eyes detect light, your ears detect sound waves, and your skin detects pressure or temperature.
Signal Transduction: These sensory inputs are converted into electrical signals by specialized cells. In the eye, for example, light is converted into electrical signals by photoreceptor cells in the retina. In the ear, sound waves are converted into electrical signals by hair cells in the cochlea.
Signal Transmission: The electrical signals are then transmitted via neurons (nerve cells) to the brain. This process involves a chain of neurons passing the signal along through a combination of electrical and chemical processes (neurotransmitters).
Processing in the Brain: Once these electrical signals reach the brain, they are interpreted by different areas of the brain. For instance, the visual cortex processes signals from the eyes to create an image, and the auditory cortex processes signals from the ears to create sound.
So, the brain doesn't receive raw sensory data like light or sound directly—it only receives and processes the electrical signals that represent this data. The fascinating part is that our experience of the world, with all its colors, sounds, textures, and tastes, is a construct of the brain interpreting these signals.
