Perhaps you're referring to Naomi Eisenberger's work on the neural basis of social pain. Her seminal paper found that the neural correlates of distress from social rejection overlapped with those of physical pain, i.e., dorsal anterior cingulate cortex and anterior insula. She's recently published a literature review on social pain in the brain ...

The source I have quoted below gives an example of the following stenographic image:- Is this perception a particular trick that my eye performs or is it processing the visual data in an alternative way? Stereograms can be viewed as three-dimensional images by providing two side-by-side views of a three-dimensional scene, rendered from slightly ...

The Lateral Preference Inventory Coren (1993) developed an inventory for lateral preference (The Lateral Preference Inventory). Several items concerned ear preference. I found the choice of items to be quite interesting. See below for the items concerned with ear preference. Based on a large adult normative sample, a total score was created for the ...

Psychophysiology is totally outside of my wheelhouse, but here it goes… Those feelings in your chest, face, arms, etc. aren't an illusion. Indeed, it's long been argued that physiological arousal (in your body) is a core component of emotional experience (e.g., James, 1884; Russell, 1980)--alongside feelings of pleasure and displeasure. Moreover, that ...

Short answer Damage to the inner ear can result in an asymmetric distortion in pitch perception between the two ears. This phenomenon can result in the same tone being perceived as a different pitch by the two ears. Background Damage to the inner ear (the cochlea) can lead to hearing loss. Hearing loss can sometimes lead to changes in perceived pitch. For ...

Seems that you are asking: I am really interested just in the way the brain creates new electrical potentials, "just on his own." and whether [sic] the brain would 'stop working', implying that there no longer is any neural activity due to the lack of external impulses. If you were to theoretically disconnect the brain from all sensory input, ...

In general, subjective sensation increases linearly with the the log of physical intensity, which is described by Fechner's law. We are sensitive to small variations when light is dim, but we need large differences in intensity under conditions of high luminance (Weber's law). This is a linear relation, but taken together with Fechner these findings are ...

Assuming your question is "Is person's ego a projection of the responses of their amygdala onto the conscious experience?", I think it would translate to "Does the amygdala determines or houses the ego". In that light, the question hinges on the meaning of ego. Given the question is asked at Cognitive Sciences SE, I assume the ego is "The part of the mind ...

In general, evidence suggests that we are attracted to contrast rather than brightness (luminance). For example, the onset of a bright light on a dark background is often used as an exogenous cue for visual attention, but a dark cue on a bright background works just as well. So, signs generally aim to be high contrast against their background. Contrast shows ...

In psychology, we call people's attitudes towards things "preferences", and the emotional experience associated with preference is referred to as "affect", or more specifically, "valence", which is positive or negative. As eluded to in the question, there is a genetic predisposition for certain preferences, such as sugar (sweetness), and some aversions, ...

As far as I know, there is just one article that explicitly mentions the generation of cross-modal qualia, i.e., visual qualia in response to tactile stimulation (Ortiz et al., 2011). Before continuing about this article I do wish to emphasize it is a single, isolated study that hasn't been supported by other studies at the time of this writing. Moreover, ...

The phenomenon of not being able to visualise has recently been dubbed "aphantasia" by Adam Zeman at Exeter: see the university's press release Can’t count sheep? You could have aphantasia. They had a year-long project which finished a few days ago called The Eye's Mind to study people at both ends of the ability spectrum. One of their objectives is to ...

I would read this paper, its mighty interesting. Books Snyder, B.(2000) Music and memory: An introduction. The MIT Press. Cambridge 291. Hemispheric Coordination and Conflict "...while listening to the melody of the popular carol "Silent Night", the right hemisphere thinks, "Ah, yes, Silent Night", while the left hemisphere thinks, "two sequences: ...

A study by Rainer et al. (2011) has shown that words are skipped and apparently filled in mentally quite often (in the order of 8 to 30% of times). Two important factors that increased skipping rates were the length of the word and the predictability of the word due to contextual constraints. Both cases apply on the word 'the', because it is short and ...

Short answer Sensations are different from thoughts and are separated in the spatial and temporal domain. The distinction between thoughts and perceptions, however, is less well defined, but can still be dealt with experimentally. Background A description of sensation is as follows: The physical process during which our sensory organs [...] respond to ...

I don't think inverted prism goggles would be a satisfactory way to empirically test the thought experiment. A key axiom of the argument is that there are no physical changes to our brains or bodies; only the qualia have changed. In a goggles design, there would be a clear physical locus of the change (and we might reasonably call this part of your body for ...

I can't zoom in on the picture, but what I see is bleeding from one color into the next along the diagonals (most evident in the green to blue and purple to red transitions). Are you saying that they are not there when you zoom in? I would think that because there is a gradient in the color transition, the gradient has to be emphasized in an angled meeting, ...

This isn't exactly what you are referring to, but I think provides a similar function and has been shown in vertebrate vision: https://en.wikipedia.org/wiki/Normalization_model Divisive normalization as a canonical computation across the brain While this does not implement histogram equalization, I think it is actually a better-suited explanation of the ...

As mentioned in the definitions section on page 2 of the paper, $D(q||p) = <ln(q/p)>_q$ is the Kullback-Leibler divergence or cross-entropy between two densities. The reason for the negative logs is that is the convention when discussing entropy in the context of information theory. This allows information to be combined additively. ...

Short answer "Perceptual competence" is "the ability to perceive". Background I Googled "perceptual competence" and the first hit was an open source article (Lencz et al., 2003). They define perceptual competence as: [The] initial representation of to-be-remembered material [in the context of working memory]. Perceptual competency itself can include ...

Extensively. Most prominently, recently, by David Poeppel, Oded Ghitza and Anne-Lise Giraud, in a series of papers. They've, to be precise, mostly focused on MEG correlations with the filtered speech amplitude envelope. Areas around the auditory cortex track it fairly well it seems. There is still much debate about what this means and where it comes from, ...

The N170 (the face selective component of the brain) is commonly mapped indeed to OFA or FFA. It's trivial to find examples for this, e.g.: this, this, this, this, this. Many more studies can be found by searching the relevant data bases, e.g. like this. Some of these include co-registered EEG/fMRI or MEG. There is some uncertainty of where exactly it ...

The symptoms belong to the Alice-in-Wonderland Syndrome, which is supposed to be very common in childhood. An interesting article appeared in the New York Times.

There are many such illusions. It mostly belongs to pattern-recognition and gestalt psychology. From German it means "shape", "form", "essence". To answer your question, I think, here there are illusory contours (when you watch and understand an illusion) and lateral inhibition (when you have got new understanding of the picture and compare it with previous ...

At least three things play a role here: Camouflage: the panda looks like the snowman in shape and coloring. Further, the ears of the panda are the buttons of the snowmen behind, i.e. the panda partly merges with the 'background' snowmen; Clutter: there are simply many, many snowmen; Distracters: The colored hats and other attributes are more salient and ...

Physics Perhaps you are asking, "Where would the energy, or the electrical potential, come from?" Short answer: Sugar. Or, at the cellular level, ATP. Point is -- nerve impulses from the senses are [probably] not the brain's main source of energy. Internal Stimulation The five senses provide external stimulation to the brain. But that stimulation takes ...

I too have experienced this sensation. I used to experience it quite often when I was younger, but I still experience it once in a blue moon. I have a friend who also sometimes experiences it. For me, it was not really the environment but rather that I felt I would become larger and smaller over several seconds, as if there were some sort of constriction ...

The root cause is almost certainly procreation. Our relationship tendencies developed along with our biology. Humans tend to have one child at a time, and human children mature very slowly. This suggests that during most of human history, it would be advantageous for a female to keep a male with her, helping to provide food and protection for herself and her ...

You have specifically asked about the "adaptations done by the brain" in your initial question and an interest in "what has been done towards finding the formula and what it was replaced with for the time being?" By formula, I'm assuming that you meant a perceptual algorithm that can be useful in machine learning and the attempt to reverse-engineer human's ...
