The brain interprets electrical signals from sensory neurons, creating experiences of pleasure and pain based on both innate and learned factors.

Experiments in sensory substitution show that the brain can adapt to new ways of perceiving the world, such as through electro-tactile signals.

We haven't evolved to perceive the world objectively; our perceptions are often predictions based on past experiences.

Thoughts can happen spontaneously or be deliberate, and the nervous system is responsible for sensation, perception, feelings, thoughts, and behaviors.

Sensation is bound by the body's receptors, which perceive various stimuli like light, pressure, and sound.

The human brain processes visual information incredibly well, mapping raw photons to a vector space representation, which is a complex task for machines.

Our physical embodiment is essential to human intelligence and consciousness, as our brains help us navigate and manipulate the complex world of objects in 3D space. The biological brain is designed for smarter movement, and all other aspects of intelligence stem from that.

The eyes collect light information and send it to the brain in a form it can understand, using specialized cells called photoreceptors, which include rods and cones.

Understanding intuition involves recognizing that our brains constantly mix conscious and unconscious signals, influencing our decisions without our awareness.
