The neural correlates of consciousness (NCC) are the minimal set of neuronal events and mechanisms sufficient for the occurrence of the mental states to which they are related. [2] Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate ...
In their study, they introduced a new factor: stimuli could be faces or non-faces, and either class could have high or low similarity. Similarity was measured by calculating the correlation between pixel values in pairs of same-category stimuli. When ERPs were compared for these conditions, they found a typical N170 effect in the low-similarity ...
In most cases, positive mood inductions impair executive function, whereas negative mood has little effect. Overall, the best supported explanation for the observed effects is that mood affects processing style, with positive mood facilitating more heuristic methods of solving problems, and negative mood facilitating more algorithmic methods ...
A meta-analytic review by McDaniel found that the correlation between intelligence and in vivo brain size was larger for females (0.40) than for males (0.25). [18] The same study also found that the correlation between brain size and Intelligence increased with age, with children showing smaller correlations. [18]
For instance, when a somatic marker associated with a positive outcome is perceived, the person may feel happy and thereby motivated to pursue that behavior. When a somatic marker associated with the negative outcome is perceived, the person may feel sad, which acts as an internal alarm to warn the individual to avoid that course of action.
Affective neuroscience is the study of how the brain processes emotions.This field combines neuroscience with the psychological study of personality, emotion, and mood. [1] The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
[4] [5] The Neural efficiency hypothesis was first introduced by Haier et al. in 1988 through a Position Emission Tomography (PET) study aimed at investigating the relationship between intelligence and brain activation. [6] PET is a type of nuclear medicine procedure that measures the metabolic activity of the cells of body tissues. [7]
The ERP is plotted with negative voltages upward, a common, but not universal, practice in ERP research. An event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. [1] More formally, it is any stereotyped electrophysiological response to a stimulus.
