Why do our dreams include sensory experiences?
In all cases, the impact of sensory stimuli on dreams suggests that the creation of dreams occurs as much in the body as it does in the mind, and underlines the role of the body in conscious experience. Changes in the kinesthetic content of dreams following somatosensory stimulation of leg muscles during REM sleep.
What is the information processing theory of dreams?
The Theory of Information-Processing This theory believes that dreams work to transfer what we experienced throughout the day into our memory. The new pieces of information we pick up are supposedly organized in the brain while we dream in REM sleep.
How are dreams explained as a psychological function?
Sigmund Freud’s theory of dreams suggests that dreams represent unconscious desires, thoughts, wish fulfillment, and motivations. 4 According to Freud, people are driven by repressed and unconscious longings, such as aggressive and sexual instincts.
Do Neurologists study dreams?
The neurology of dreaming has remained misunderstood until recent distinctions, however. The information available via modern techniques of brain imaging has provided new bases for the study of the dreaming brain. Patients reported that their visual images were dim and hard to evoke.
Why do external stimuli trigger dreams?
Research has shown that external stimuli presented during sleep can affect dream content, thus reflecting information processing of the sleeping brain. Olfactory stimuli should have a stronger effect on dream emotions because their processing is linked directly to the limbic system.
What theory of dreaming proposes that dreaming involves information processing memory and problem solving?
Cognitive Theory of dreaming- Theory proposing that we can understand dreaming by applying the same cognitive concepts we use in studying the waking mind; rests on the idea that dreams are essentially subconscious cognitive processing involving information and memory.
What did Jung believe about dreams?

What are visual evoked potentials used for?
Visual evoked potentials (VEP) are used to assess the visual pathways through the optic nerves and brain. A normal VEP response to a pattern-reversal stimulus is a positive mid occipital peak that occurs at a mean latency of 100 ms.
What is the pathophysiology of visual evoked potential (VEP)?
It should always be kept in mind that the VEP is a downstream response that arises largely in the visual cortex and can be affected by disease anywhere upstream in the visual system (eg, the retina). Retinal dystrophies including but not limited to central serous retinopathy, macular diseases, and glaucoma have been reported to affect VEPs.
What factors affect visual evoked potential responses?
There are multiple factors that can affect the VEP responses, including retinal disease, age, and gender, just to name a few. Interpretation of VEPs must be considered within the context of the subject’s clinical appearance and the information available from other tests and examinations.
What is the difference between sound and amblyopic visual evoked potentials?
In amblyopic patients, the VEPs evoked to pattern stimuli from the amblyopic eye are generally smaller in amplitude compared to the VEPs recorded from the sound eye. However, note that different types of amblyopia can result in different VEP findings.
