Acute stress can also affect a person's neural correlates which interfere with the memory formation. During a stressful time, a person's attention and emotional state may be affected, which could hinder the ability to focus while processing an image. Stress can also enhance the neural state of memory formation. [clarification needed] [29]
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 ...
Students and workers may face performance pressure stress from exams and project deadlines. Adverse experiences during development (e.g. prenatal exposure to maternal stress, [55] [56] poor attachment histories, [57] sexual abuse) [58] are thought to contribute to deficits in the maturity of an individual's stress response systems.
One study has shown that Extraversion and Agreeableness are positively correlated with overall neural activity in the default mode network. [51] Assessing the relationship between neural activity in brain networks and personality traits is an important first step for identifying where the neurobiological basis of personality traits may be ...
The visual thalamus also relays the information to the visual cortex and is processed to see if the stimuli poses a potential threat. If so, this information is relayed to the amygdala and the muscle contraction, increased heart rate and blood pressure begins, thus activating the sympathetic neuronal pathway. A presentation of a neutral visual ...
Physiological psychology is a subdivision of behavioral neuroscience (biological psychology) that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments.
a social evaluative threat (negative social evaluation possibly leading to social rejection). It has also been shown that elevated levels of glucocorticoids enhance memory for emotionally arousing events but lead more often than not to poor memory for material unrelated to the source of stress/emotional arousal.
Electroencephalography has been used for meditation research.. The psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as functional magnetic resonance imaging and electroencephalography, which are able to observe brain physiology and neural activity in living subjects ...
