What makes synesthesia different from drug-induced hallucinations is that synesthetic sensations are highly consistent: for particular synesthetes, the note F is always a reddish shade of rust, a 3 is always pink or truck is always blue. These associations are also constant for synesthetes. This indicates that Jean's memory of the alligator attack is likely ____. Corrections? Recent findings suggest that research on synesthesia offers a unique opportunity to study the neural basis of subjective experiences in healthy and pathological brains. Sensation and perception are the underlying processes operating in visual illusions. And then at primary school, I realized not everyone saw colors and imagery in this waybut, she went on, it was only in university that I realized that it was a real minority of us who had synesthesia..

One synesthete who spoke to Medical News Today gave us a highly impressive description of her experience of color-auditory synesthesia. Now, reports Michael Price at Science, researchers have identified some of the genes that may be responsible for these unusual experiences. Understanding of sleep increased by the study of: brain waves, eye movements, chin muscle tension, heart rate, respiration rate, Lightest sleep, hypnagogic state, myoclonia (startle awake, feeling of falling) theta waves occur, Somewhat more deeply asleep (mid asleep) - Sleep spindles occur - K complex occur, Deep sleep, delta waves 20% slow wave deep sleep begins, heart and breathing slow and regular, Deepest sleep, delta waves reach nearly 100%, blood pressure & brain activity at lowest points in 24 hour period, Called active sleep, paradoxical sleep, or dream sleep (20-25% of a nights sleep), Intense brain activity, brain temperature rises rapidly, sexual excitement in both genders, epinephrine release leads to increase in blood pressure, heart rate respiration, Body appears to be calm, large muscles become paralyzed, eyes dart around, dreaming occurs in 80% of people, consolidation of learning and memory (all night studying doesn't help), perceptual or motor skills increase after 8-10 hours of sleep, always get at least 3 hours of sleep each night, sleep walking, occurs during partial arousal from stage 4 sleep, sleeptalking, occurs during any sleep stage, is more frequent among children, happens during partial arousal from stage 4 sleep, usually begins with piercing scream, are frightening dreams that occur during REM sleep, partially wake up during REM Sleep, unable to move or speak, characterized by excessive daytime sleepiness and uncontrollable attacks of REM sleep (associated with sleep paralysis), periods during sleep when breathing stops, the individual must awaken briefly in order to breathe, difficulty falling or staying asleep, sleep that is light, rests or of poor quality, believed dreams satisfy unconscious sexual and aggressive desires and must be disguised, the content of a dream as recalled by the dreamer, the plot of the dream, dreams are an expression of ongoing concerns and can resolve or clarify current problems, relate images in dreams to things in your waking life, dreams are the brains attempt to make sense of the random brain activity during REM sleep, we construct a story around the brain activity, any substance that alters mood perception or thought, needing larger amounts of the substance to achieve the same subjective effect, physical responses to the removal of habitually used substance, a compulsive physical or psychological dependence on a substance that continues despite negative consequences, Speed up the central nervous system, low moderate levels are exciting , confident, and euphoric, high levels are anxious, jittery, and hyper, overdose are convulsions, heart failure, death, caffeine, meth, cocaine, nicotine, ritalin/adderall, ecstasy and Molly, slow down the central nervous system, low-moderate levels are calm, drowsy, reduced anxiety, and inhibitions, high levels are insensitivity to pain and other senses, and overdose are irregular heartbeat or death, derived from the poppy plant, mimics the body's endorphins, can reduce anxiety or cause euphoria, and are common pain killers like opium, heroine, methadone, morphine, oxycontin, heroine, hydrocondone, disrupt normal thought process, reactions can be pleasant or not, some produce visual hallucinations like LSD, mushrooms, PCP, and Molly can have hallucinogenic effects, basically give schizophrenia for a short period of time, does not fit neatly into any class of drugs, some stimulating effects like euphoria or relaxing affects, but could make sensations more intense, and too much can interfere with memory, coordination, concentration and reaction times, induced altered consciousness, state of deep relaxation and heightened suggestibility, can have analgesic effects (pain killing), induced altered consciousness, rooted in ancient eastern religions, state of alert relaxation, improves immune system, lowers BP and cholesterol, creates a general feeling of well being, organizing and interpreting the information, the smallest magnitude of a stimulus that can be detected (the weakest detectable stimulus), the smallest detectable difference between two stimuli, must have light to see, light is composed of waves that give us hue, brightness, and saturation, complexity of light (gives us pure versus paler colors), ROY G BIV, can only see red, orange, yellow, green, blue, indigo, violet, blue has shorter wavelengths and red has longer wavelengths, protective coating on the surface of the eye, the colored part of the eye that regulates the amount of light that enters, the transparent portion of the eye that focuses light onto the retina, images fall here, sensory receptor cells are here, receptor cells that code info about light and dark (located outside the center of the retina) 120 million cells in each eye, receptor cells that code info about color (located at the center of the retina) 6 million cells in each eye, the spot where the cones are concentrated (images focused directly onto the fovea are clearest because of the high concentration of cones), the nerve that carries visual neural messages to the brain (the area where the optic nerve attaches contains no rods or curves and therefore is a blind spot), the first level of color processing, there are 3 different kinds of cones in the eye and each respond to light in either red, blue, or green wavelengths therefore all sensation of color result from stimulating a combination of these 3 cones, yet doesn't explain red/green color blindness or color after images, second level of color processing, in addition to 3 types of cones (cone for red, blue, and green) there are "opponent process mechanisms" which respond to either the red green or the yellow-blue wavelengths, when we see something, whatever is the center of our attention is the figure, whatever is in the background is the ground (we can change our perception of the same image by switching the figure and the ground), 4 Gestalt Principles of Perceptual Organization, proximity, closure, similarity, continuation, things that are close together are grouped together in the mind as if they belong together, incomplete figures tend to be seen as complete because our brain fills in missing information, similar things are sense as being related, images are seen in ways that produce smooth continuation, the perception of objects remains unchanged, even when the sensation of the object is changing, we understand the brightness of an object does not change even when the object is dimly lit, we understand that colors do not change despite different conditions of light, cues in the environment that suggest depth and can be seen by only one eye, linear perspective parallel lines appear to come together as they go off into the distance (railroad tracks), eyes angle inward as an object gets closer to us, because each retina is a few inches apart, they have slightly different images and this helps with depth perception, pain messages are sent through two distinct pathways: rapid (first pain) and slow (second pain), there are neural gates (endorphins) that control the transmission of pain impulses that gate can open (slow pain messages are not blocked, therefore we experience pain) or closed (slow pain messages are blocked, and we do not experience pain), amputees often feel the amputated limb as if it is still there and sometimes feel pain in the missing limb, the neurons in charge of missing limb don't know that it is gone - but eyes see that the limb is gone - mismatch between eyes and neurons, Allows the eyes to see the missing limb as "working", stops mismatch between neurons and eyes, Atkinson-Shriffin proposed this model in 1968.
