unconscious
Subliminal perception refers to the detection of sensory information that occurs below the level of conscious awareness.
thalamus, which acts as a relay station for sensory information traveling to the cerebral cortex. It plays a crucial role in processing sensory inputs before they reach higher brain regions responsible for perception.
I have added a good link to this answer with a website which is dedicated to the brain with comparisons to different species to humans its got everything you ever wanted to know about the brain
Sensory
Unconscious
The ridges of the hemisphere refer to the gyri, which are the raised folds on the surface of the brain. These gyri play a role in increasing the surface area of the brain, allowing for more complex neural connections. They are involved in various functions such as sensory perception, motor control, and higher-level thinking.
Sensation and Perception are intimately relates to one another but plays a different role. Sensation or the 5 Senses which are sense of touch, taste, sight, sound and smell. This 5 senses are sent to our brain and this is where perception takes place. Perception is the process were our senses communicate with our brain.
-Level I: The receptor level corresponding to the sensory receptors -Level II: The circuit level corresponding to the ascending pathways -Level III: The perceptual level corresponding to the awareness of the incoming stimuli
Bottom-up theory refers to an approach in which complex systems or behaviors arise from the interactions of simpler components. In psychology, bottom-up theory suggests that perception starts with the individual sensory stimuli which are then processed by the brain to form a complete picture or understanding. This is in contrast to top-down processing, which starts with higher-level cognitive factors influencing perception.
Sensation and perception are not the same thing. Sensation refers to the process of detecting physical stimuli from the environment, while perception involves organizing and interpreting those stimuli to make sense of the world. Sensation is the initial step in processing sensory information, while perception is the higher-level cognitive process that follows.
The proximal stimulus is found at the level of the sensory receptors in the body. It refers to the physical energy or information that directly interacts with these receptors, such as light hitting the retina in the eye or sound waves impacting the ear. This interaction is crucial for the process of perception, as it transforms external stimuli into neural signals that the brain interprets.
The part of the brain primarily concerned with visual perception is the occipital lobe, located at the back of the brain. It contains the primary visual cortex (V1), which processes visual information received from the eyes. This area plays a crucial role in interpreting aspects such as color, motion, and depth. Other areas, such as the temporal and parietal lobes, also contribute to higher-level visual processing and perception.
